Kafka Month-to-month Digest – July 2021 – IBM Developer


That is the forty second version of the Kafka Month-to-month Digest. On this version, I’ll cowl what occurred within the Apache Kafka neighborhood in July 2021.

For final month’s digest, see Kafka Month-to-month Digest: June 2021.



The discharge course of for Kafka 3.0.0 continued. Code freeze occurred on July 20. There are presently a handful of blocker JIRAs that must be mounted. As soon as these are addressed, Konstantine Karantasis will begin constructing the primary launch candidate.


Final month, the neighborhood submitted 6 KIPs (KIP-760 to KIP-765), and these are those that caught my eye.

  • KIP-762: Delete Dedicated Join Information. As a result of Kafka Join presents connectors for thus many programs, it’s attainable to make use of it to maneuver knowledge from a system immediately into one other. In such pipelines, Kafka is simply incidental and there’s no have to hold the info in it. The aim of this KIP is to supply a mechanism to enhance this state of affairs and have Join routinely delete information as soon as they’ve been written to the goal system.

  • KIP-763: Vary queries with open endpoints. In Kafka Streams, a state retailer might be queried utilizing a vary. Nonetheless, Kafka Streams solely accepts closed ranges, the place each the from and to keys are specified. This KIP proposes to permit passing null for both certain to assist use instances wanting to question information with a key smaller or larger a sure fixed.

On this part, I’ll cowl releases of some neighborhood initiatives. This solely consists of initiatives which are open supply.
