When this comes in to place we need cache in OzoneManager HA to > handle/server the requests for validation/returning responses. > > This Jira will implement Cache as an integral part of the table. In this way > users using this table does not need to handle like check cache/db. For this, > we can update get API in the table to handle the cache. > > This Jira will implement: > # Cache as a part of each Table. > # Uses this cache in get(). > # Exposes api for cleanup, add entries to cache. > Usage to add the entries in to cache will be done in further jira's. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
