This patch refactors those steps. > It also adds an isExist API in the metadata store so that we dont need to > deserialize the byte[] to Object while doing a simple _table.get(key) != > null_ check. > On applying the patch, the OM + SCM (With dummy datanodes) write performance > improves by around 3 - 6x based on number of existing keys in the OM RocksDB. > Thanks to [~nandakumar131] who helped with this patch. -- 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
