Description
This PR improves the path parsing and JSONPath handling when configuring advanced transforms in the ML processors. Added detailed comments in the source code for readability.
generateTransform
to handle more edge cases and be consistent without the backend handles path parsing for the different scenarios (input vs. output, ingest vs. search request vs. search response).sanitizeJSONPath()
fn used in 2 places: 1/ when auto-populating keys for the query or document JSONs (ensures they will run consistently on frontend & backend), and 2/ when converting to a template (to ensure it runs properly on the backend).isIndefiniteJsonPath()
to help make the return values of a JSONPath execution consistent. Note: this is not a full-featured fn. The frontend libraries do not have any configuration similar toALWAYS_RETURN_LIST
, nor a mechanism to determine whether a path is definite or indefinite. The purpose of this function is to broadly cover the majority of use cases to mimic the implementation as close as possible.More details on the fixes this covers in the related issue #478 .
