Summary: Try to estimate the cell count for adding into WALEdit Key: HBASE-15204 URL: https://issues.apache.org/jira/browse/HBASE-15204 Project: HBase Issue Type: Sub-task Reporter: ramkrishna.s.vasudevan Assignee: ramkrishna.s.vasudevan Fix For: 2.0.0 The write path profiling shows that when we try to add Cells to WALEdits we try to do a lot of Array copy inorder to grow the Arraylist backing the WALEdits. In a simple one min profiling of the write path with 50 YCSB threads shows around 261MB of allocation done for the Array copy to happen. We can try to avoid that. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
