Glossary · Dutch: Chunking (deelberichten)
Chunking (sub-messages)
The Release 2026 processing protocol for large messages: the sender splits a message into numbered sub-messages with a shared currentChunkId, chunkSequenceNumber, totalNumberOfChunks and JMESPath references (chunkFragmentPaths); the receiver reassembles them.
Where the term lands in the messages
- chunking.default.currentChunkIdUnique reference (id) of the current chunk.
- chunking.default.chunkSequenceNumberSequence number of the current chunk.
- chunking.default.totalNumberOfChunksTotal number of chunks the message has been split into.
- chunking.default.chunkFragmentPathsArray of JMESPath references to the message fragments used within the current chunk.
