RequireDocumentLua
The path of a Lua script to run, to decide whether to ingest an item or ignore it.
NOTE: To use this functionality in NiFi, set the advanced connector property adv:RequireDocumentLua. You can set the value to either a script file path or the content of the script. OpenText recommends setting this property from the guided setup wizard, on the advanced configuration page, because the wizard provides useful examples.
The script has access to document metadata that has been retrieved by the connector, so if the connector configuration parameters do not provide sufficient flexibility you can add any custom content selection logic that you require.
The connector runs the script before binary files are downloaded, so excluding items in this way is more efficient that allowing the connector to retrieve them and then discarding them later in the ingest pipeline.
The script must contain a function named handler, that should return true to ingest the document or false to discard it.
function handler(config, document, params)
local required = true
-- required = filtering logic
return required
