stack commented on HBASE-13703: ------------------------------- So we create one of these every time we ship an edit? > ReplicateContext should not be a member of ReplicationSource > ------------------------------------------------------------ > > Key: HBASE-13703 > URL: https://issues.apache.org/jira/browse/HBASE-13703 > Project: HBase > Issue Type: Bug > Reporter: Lars Hofhansl > Assignee: Lars Hofhansl > Priority: Minor > Attachments: 13703.txt > > > The ReplicateContext object is created once per ReplicationSource and then > reused when we have something to ship to the sinks. > This is a misguided optimization. ReplicateContext is very lightweight > (definitely compared to the all the work and copying the ReplicationSource is > doing) and, crucially, it prevent the the entries array from being collected > after it was successfully copied to the sink, wasting potentially a lot of > heap. > The entries array itself holds reference to WAL entries on the heap, that now > also cannot be collected. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
