-------------------------------
Any pictures to show us [~apurtell] w/ the hot allocations? Or, dumb question,
where is SeekerState? Thanks.
> Explore object pooling of SeekerState

> Project: HBase
> Issue Type: Task
> Reporter: Andrew Purtell
>
> In read workloads 35% of the allocation pressure produced by servicing RPC
> requests comes from SeekerState.<init> of the DataBlockEncoder implementation
> currently in use, where we allocate two byte arrays of
> INITIAL_KEY_BUFFER_SIZE in length. There's an opportunity for object pooling
> of SeekerState here. Subsequent code checks if those byte arrays are sized
> sufficiently to handle incoming data to copy. The arrays will be resized if
> needed.
