Buffer Payloads

These actions provide ability to buffer multiple event payloads into a single batch event.

Buffer Payloads Actions

Buffer

Buffers payload of the events received and releases them as a single combined event with array of input payloads in either of the following cases:

• When the runner performs a commit operation, based on its settings or a commit command received.

• When the number of buffered events reaches the buffer size provided in event parameters.

Event metadata fields applicable for this action are as follows:

Table

Field	Definition	Example	Default
Input Element	Json path for payload element to buffer	parameters	-
Output Element	Json path for payload element to output buffered data	batch	-

JSON Schema

With event metadata parameters as:

Table

Parameter	Definition	Example	Default
Input Pattern	JMES path for transforming input element	{"id": productid}	-
Output Pattern	JMES path for transforming buffered data, which is an array	@[?id>0]	-
Buffer ID	Unique id for buffering similar payloads together	product_ids	-
Buffer Size	Max number of records to buffer	10	-

JSON Schema

bufferSize is defined at action level instead of handler level. This allows real-time changes for different buffer types without rebuilding the handler.

This action can improve performance for handlers that support batched requests, such as bulk writes or batched rule calculations.
