The extract command is a distributable streaming command.


The alias for the extract command is kv.


Example 1:

Extract field-value pairs that are delimited by the pipe or semicolon characters ( |; ). Extract values of the fields that are delimited by the equal or colon characters ( =: ). The delimiters are individual characters. In this example the "=" or ":" character is used to delimit the key value. Similarly, a "|" or ";" is used to delimit the field-value pair itself.

... | extract pairdelim="|;", kvdelim="=:"

Example 2:

Extract field-value pairs and reload field extraction settings from disk.

... | extract reload=true

Example 3:

Extract field-value pairs that are defined in the stanza 'access-extractions' in the transforms.conf file.

... | extract access-extractions
