Directory

The Directory origin reads data from files in a directory. The file names must all share a file name pattern and be fully written. To read data from an active file that is still being written to, use the File Tail origin.

When you configure the Directory origin, you define the directory to use, read order, file name pattern, file name pattern mode, and the first file to process. You can use glob patterns or regular expressions to define the file name pattern that you want to use. When using the last-modified timestamp read order, you can configure the origin to read from subdirectories.

You can also enable reading compressed files or files in a late arriving directory. After processing a file, Directory can keep, archive, or delete the file.

When the pipeline stops, Directory notes where it stops reading. When the pipeline starts again, Directory continues processing from where it stopped by default. You can reset the origin to process all requested files.

Directory includes record header attributes that enable you to use the origins of a record in pipeline processing.

The origin can also generate events for an event stream. For more information about dataflow triggers and the event framework, see Dataflow Triggers Overview.

File Name Pattern and Mode

Use a file name pattern to define the files to process. You can use either a glob pattern or a regular expression to define the file name pattern.

The origin processes files based on the file name pattern mode, file name pattern, and specified directory. For example, if you specify a /logs/weblog/ directory, glob mode, and *.json as the file name pattern, the Directory origin processes all files with the "json" extension in the /logs/weblog/ directory.

The origin processes files in order based on the specified read order.

For more information about glob syntax, see https://en.wikipedia.org/wiki/Glob_(programming)#Syntax.

For more information about regular expressions, see Regular Expressions Overview.

Read Order

The Directory origin reads files in ascending order based on the last modified timestamp or the file name:

Last Modified Timestamp
The Directory origin can read files in ascending order based on the last modified timestamp. When the origin reads from a secondary location - not the directory where the files are created and written - the last-modified timestamp should be when the file is moved to the directory to be processed.
Tip: Avoid moving files using commands that preserve the existing timestamp, such as cp -p. Preserving the existing timestamp can be problematic in some cases, such as moving files across time zones.
When ordering based on timestamp, any files with the same timestamp are read in lexicographically ascending order based on the file names.
For example, when reading files with the log*.json file name pattern, the origin reads the following files in the following order:
File Name
Last Modified Timestamp
log-1.json
APR 24 2016 14:03:35
log-0054.json
APR 24 2016 14:05:03
log-0055.json 
APR 24 2016 14:45:11
log-2.json
APR 24 2016 14:45:11
Lexicographically Ascending File Names
The Directory origin can read files in lexicographically ascending order based on file names. Note that lexicographically ascending order reads the numbers 1 through 11 as follows:
1, 10, 11, 2, 3, 4... 9
For example, when reading files with the web*.log file name pattern, Directory reads the following files in the following order:
web-1.log
web-10.log
web-11.log
web-2.log
web-3.log
web-4.log
web-5.log
web-6.log
web-7.log
web-8.log
web-9.log
To read these files in logical and lexicographically ascending order, you might add leading zeros to the file naming convention as follows:
web-0001.log
web-0002.log
web-0003.log
...
web-0009.log
web-0010.log
web-0011.log

Reading from Subdirectories

When using the Last-Modified Timestamp read order, the Directory origin can read files in subdirectories of the specified file directory.

When you configure the origin to read from subdirectories, it reads files from all subdirectories. It reads files in ascending order based on timestamp, regardless of the location of the file within the directory.

For example, you configure Directory to read from the /logs/ file directory, select the Last-Modified Timestamp read order, and enable reading from subdirectories. Directory reads the following files in the following order based on timestamp, even though the files are written to different subdirectories.

File Name
Directory
Last Modified Timestamp
log-1.json
/logs/west/
APR 24 2016 14:03:35
log-0054.json
/logs/east/
APR 24 2016 14:05:03
log-0055.json 
/logs/west/
APR 24 2016 14:45:11
log-2.json
/logs/
APR 24 2016 14:45:11

Post-Processing Subdirectories

When the Directory origin reads from subdirectories, it uses the subdirectory structure when archiving files during post-processing. You can archive files when the origin completes processing a file or when it cannot fully process a file.

For example, say you configure the origin to archive processed files to a "processed" archive directory. After successfully reading the files in the example above, it writes them to the following directories:
File Name
Archive Directory
log-1.json
/processed/logs/west/
log-0054.json
/processed/logs/east/
log-0055.json 
/processed/logs/west/
log-2.json
/processed/logs/

First File for Processing

Configure a first file for processing when you want Directory to ignore one or more existing files in the directory.

When you define a first file to process, Directory starts processing with the specified file and continues based on the read order and file name pattern. When you do not specify a first file, Directory processes all files in the directory that match the file name pattern.

For example, say Directory reads files based on last-modified timestamp. To ignore all files older than a particular file, use that file name as the first file to process.

Similarly, say you have Directory reading files based on lexicographically ascending file names, and the file directory includes the following files: web_001.log, web_002.log, web_003.log.

If you configure web_002.log as the first file, Directory reads web_002.log and continues to web_003.log. It skips web_001.log.

Late Directory

You can configure Directory to read files in a late directory - a directory that appears after the pipeline starts.

When reading from a late directory, the origin does not validate the directory path when you start the pipeline. If the directory does not exist when the pipeline starts, the origin waits indefinitely for the appearance of the directory and a file to process.

For example, say you read files in the following directory:

/logs/server/

The directory does not exist when you start the pipeline, so Directory waits until the directory and a file matching the file name pattern appears, and then processes the data.

After /logs/server appears, the origin can then process the following files that are written to the directory:

/logs/server/log.json
/logs/server/log1.json
/logs/server/log2.json

Record Header Attributes

The Directory origin creates record header attributes that include information about the origins of the record. You can use record:attribute functions to use the attribute information in pipeline processing. For more information about record header attributes, see Record Header Attributes.

The Directory origin creates the following record header attributes:
  • filename - Provides the name of the file where the record originated.
  • file - Provides the file path and file name where the record originated.
  • offset - Provides the file offset in bytes. The file offset is the location in the file where the record originated.

Event Generation

The Directory origin can generate events that you can use in an event stream. When you enable event generation, the origin generates event records each time the origin starts or completes reading a file.

Directory can be used in any logical way. For example:

For more information about dataflow triggers and the event framework, see Dataflow Triggers Overview.

Event Records

Event records generated by the Directory origin have the following event-related record header attributes. Record header attributes are stored as String values:
Record Header Attribute Description
sdc.event.type Event type. Uses one of the following types:
  • new-file - Generated when the origin starts processing a new file.
  • finished-file - Generated when the origin completes processing a file.
sdc.event.version An integer that indicates the version of the event record type.
sdc.event.creation_timestamp Epoch timestamp when the stage created the event.
Both types of Directory event records include the following field:
Event Record Field Description
filepath Path and name of the file that the origin started or finished processing.

Buffer Limit and Error Handling

The Directory origin passes each record to a buffer. The size of the buffer determines the maximum size of the record that can be processed. Decrease the buffer limit when memory on the Data Collector machine is limited. Increase the buffer limit to process larger records when memory is available.

When a record is larger than the specified limit, Directory processes the source file based on the stage error handling:
Discard
Directory discards the record and all remaining records in the file, and then continues processing the next file.
Send to Error
With a buffer limit error, Directory cannot send the record to the pipeline for error handling because it is unable to fully process the record.

Instead, Directory sends a message to the Monitor console to indicate that a buffer overrun error occurred. The message includes the file and offset where the buffer overrun error occurred. The information displays in the pipeline history and displays as an alert when you monitor the pipeline.

If an error directory is configured for the stage, Directory moves the file to the error directory and continues processing the next file.

Stop Pipeline
Directory stops the pipeline and sends a message to the Monitor console to indicate that a buffer overrun error occurred. The message includes the file and offset where the buffer overrun error occurred. The information displays as an alert and in the pipeline history.
Note: You can also check the Data Collector log file for error details.

Data Formats

The Directory origin processes data differently based on the data format. Directory processes the following types of data:
Avro
Generates a record for every Avro record.
The origin expects each file to contain the Avro schema and uses the schema to process the Avro data.
The origin reads files compressed by Avro-supported compression codecs without requiring additional configuration.
Delimited
Generates a record for each delimited line. You can use the following delimited format types:
  • Default CSV - File that includes comma-separated values. Ignores empty lines in the file.
  • RFC4180 CSV - Comma-separated file that strictly follows RFC4180 guidelines.
  • MS Excel CSV - Microsoft Excel comma-separated file.
  • MySQL CSV - MySQL comma separated file.
  • Tab-Separated Values - File that includes tab-separated values.
  • Custom - File that uses user-defined delimiter, escape, and quote characters.
You can use a list or list-map root field type for delimited data, optionally including the header information when available.
You can also replace a string constant with null values.
When a record exceeds the user-defined maximum record length, the origin cannot continue processing data in the file. Records already processed from the file are passed to the pipeline. The behavior of the origin is then based on the error handling configured for the stage:
  • Discard - The origin continues processing with the next file, leaving the partially-processed file in the directory.
  • To Error - The origin continues processing with the next file. If a post-processing error directory is configured for the stage, the origin moves the partially-processed file to the error directory. Otherwise, it leaves the file in the directory.
  • Stop Pipeline - The origin stops the pipeline.
For more information about the root field types, see Delimited Data Root Field Type.
JSON
Generates a record for each JSON object. You can process JSON files that include multiple JSON objects or a single JSON array.
When an object exceeds the maximum object length defined for the origin, the origin cannot continue processing data in the file. Records already processed from the file are passed to the pipeline. The behavior of the origin is then based on the error handling configured for the stage:
  • Discard - The origin continues processing with the next file, leaving the partially-processed file in the directory.
  • To Error - The origin continues processing with the next file. If a post-processing error directory is configured for the stage, the origin moves the partially-processed file to the error directory. Otherwise, it leaves the file in the directory.
  • Stop Pipeline - The origin stops the pipeline.
Log
Generates a record for every log line.
When a line exceeds the user-defined maximum line length, the origin truncates longer lines.
You can include the processed log line as a field in the record. If the log line is truncated, and you request the log line in the record, the origin includes the truncated line.
You can define the log format or type to be read.
Protobuf
Generates a record for every protobuf message.
Protobuf messages must match the specified message type and be described in the descriptor file.
When the data for a record exceeds 1 MB, the origin cannot continue processing data in the file. The origin handles the file based on file error handling properties and continues reading the next file.
For information about generating the descriptor file, see Protobuf Data Format Prerequisites.
SDC Record
Generates a record for every record. Use to process records generated by a Data Collector pipeline using the SDC Record data format.
For error records, the origin provides the original record as read from the origin in the original pipeline, as well as error information that you can use to correct the record.
When processing error records, the origin expects the error file names and contents as generated by the original pipeline.
Text
Generates a record for each line of text or for each section of text based on a custom delimiter.
When a line or section exceeds the maximum line length defined for the origin, the origin truncates it. The origin adds a boolean field named Truncated to indicate if the line was truncated.
For more information about processing text with a custom delimiter, see Text Data Format with Custom Delimiters.
Whole File
Streams whole files from the origin system to the destination system. You can specify a transfer rate or use all available resources to perform the transfer.
The origin generates two fields: one for a file reference and one for file information. For more information, see Whole File Data Format.
XML
Generates records based on a user-defined delimiter element. Use an XML element directly under the root element or define a simplified XPath expression. If you do not define a delimiter element, the origin treats the XML file as a single record.
Generated records include XML attributes and namespace declarations as fields in the record by default. You can configure the stage to include them in the record as field attributes.
You can include XPath information for each parsed XML element and XML attribute in field attributes. This also places each namespace in an xmlns record header attribute.
Note: Field attributes and record header attributes are written to destination systems automatically only when you use the SDC RPC data format in destinations. For more information about working with field attributes and record header attributes, and how to include them in records, see Field Attributes and Record Header Attributes.
When a record exceeds the user-defined maximum record length, the origin cannot continue processing data in the file. Records already processed from the file are passed to the pipeline. The behavior of the origin is then based on the error handling configured for the stage:
  • Discard - The origin continues processing with the next file, leaving the partially-processed file in the directory.
  • To Error - The origin continues processing with the next file. If a post-processing error directory is configured for the stage, the origin moves the partially-processed file to the error directory. Otherwise, it leaves the file in the directory.
  • Stop Pipeline - The origin stops the pipeline.
Use the XML data format to process valid XML documents. For more information about XML processing, see XML Data Format and Data Processing.
Tip: If you want to process invalid XML documents, you can try using the text data format with custom delimiters. For more information, see Processing XML Data with Custom Delimiters.

Log Formats

When you use an origin to read log data, you define the format of the log files to be read.

You can read log files that use the following log formats:

Common Log Format
A standardized text format used by web servers to generate log files. Also known as the NCSA (National Center for Supercomputing Applications) Common Log format.
Combined Log Format
A standardized text format based on the common log format that includes additional information. Also known as the Apache/NCSA Combined Log Format.
Apache Error Log Format
The standardized error log format generated by the Apache HTTP Server 2.2.
Apache Access Log Custom Format
A customizable access log generated by the Apache HTTP Server 2.2. Use the Apache HTTP Server version 2.2 syntax to define the format of the log file.
Regular Expression
Use a regular expression to define the structure of log data, and then assign the field or fields represented by each group.
Use any valid regular expression.
Grok Pattern
Use a grok pattern to define the structure of log data. You can use the grok patterns supported by Data Collector. You can also define a custom grok pattern and then use it as part of the log format.
For more information about supported grok patterns, see Defining Grok Patterns.
log4j
A customizable format generated by the Apache Log4j 1.2 logging utility. You can use the default format or specify a custom format. Use the Apache Log4j version 1.2 syntax to define the format of the log file.
You can also specify the action to take when the origin encounters an error when parsing a line. You can skip the line and optionally log an error. If you know that the unparsable information is part of a stack trace, you can have the origin include the unparsable information as a stack trace to the previous parsable line.

Configuring a Directory Origin

Configure a Directory origin to read data from files in a directory.

When you configure Directory, you define file properties, including the data format to process. Then, you define post-processing options and the properties specific to the data format.

    XML Property Description
    Compression Format The compression format of the files:
    • None - Processes only uncompressed files.
    • Compressed File - Processes files compressed by the supported compression formats.
    • Archive - Processes files archived by the supported archive formats.
    • Compressed Archive - Processes files archived and compressed by the supported archive and compression formats.
    Delimiter Element
    Delimiter to use to generate records. Omit a delimiter to treat the entire XML document as one record. Use one of the following:
    • An XML element directly under the root element.

      Use the XML element name without surrounding angle brackets ( < > ) . For example, msg instead of <msg>.

    • A simplified XPath expression that specifies the data to use.

      Use a simplified XPath expression to access data deeper in the XML document or data that requires a more complex access method.

      For more information about valid syntax, see Simplified XPath Syntax.

    Include Field XPaths Includes the XPath to each parsed XML element and XML attribute in field attributes. Also includes each namespace in an xmlns record header attribute.

    When not selected, this information is not included in the record. By default, the property is not selected.

    Note: Field attributes and record header attributes are written to destination systems automatically only when you use the SDC RPC data format in destinations. For more information about working with field attributes and record header attributes, and how to include them in records, see Field Attributes and Record Header Attributes.
    Namespaces Namespace prefix and URI to use when parsing the XML document. Define namespaces when the XML element being used includes a namespace prefix or when the XPath expression includes namespaces.

    For information about using namespaces with an XML element, see Using XML Elements with Namespaces.

    For information about using namespaces with XPath expressions, see Using XPath Expressions with Namespaces.

    Use the Add icon to add additional namespaces.

    Output Field Attributes Includes XML attributes and namespace declarations in the record as field attributes. When not selected, XML attributes and namespace declarations are included in the record as fields.
    Note: Field attributes are automatically included in records written to destination systems only when you use the SDC RPC data format in the destination. For more information about working with field attributes, see Field Attributes.

    By default, the property is not selected.

    Max Record Length (chars)

    The maximum number of characters in a record. Longer records are diverted to the pipeline for error handling.

    This property can be limited by the Data Collector parser buffer size. For more information, see Maximum Record Size.

    Charset Character encoding of the files to be processed.
    Ignore Ctrl Characters Removes all ASCII control characters except for the tab, line feed, and carriage return characters.
