Description
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.
