----------------------------------------------
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.
