> 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.
