Randall Hauch created KAFKA-2594: ------------------------------------ Summary: Add a key-value store that is a fixed-capacity in-memory LRU cache Key: KAFKA-2594 URL: https://issues.apache.org/jira/browse/KAFKA-2594 Project: Kafka Issue Type: Sub-task Components: kafka streams Reporter: Randall Hauch Assignee: Randall Hauch Fix For: 0.9.0.0
The current {{KeyValueStore}} implementations are not limited in size, and thus are less useful for some use cases. This subtask will add a simple key-value store that maintains in memory at most a maximum number of entries that were recently read or written. When the cache size reaches the capacity and a new entry is to be added, the least recently used entry will be automatically purged from the cache. This key-value store will extend {{MeteredKeyValueStore}} for monitoring and recording of changes to a backing topic, enabling recovery of the cache contents from the replicated state. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
