Motivation

Currently when restoring a state store in a Kafka Streams application we put one key-value at a time into the store.  This proposal aims to make this recovery more efficient by allowing for a "putAll" functionality allowing for bulk writes by the underlying state store implementation.

Public Interfaces

This KIP will add a method the to StateRestroreCallback interface:

void restoreAll(List<KeyValue<byte[], byte[]>>)

Compatibility, Deprecation, and Migration Plan

• • This is purely an addition of a new method. It will not cause any compatibility issues.
