Ah, I updated the description on the issue.
Next time I'm working with JFR I'll capture that info.

> Explore object pooling of SeekerState

> In read workloads 35% of the allocation pressure produced by servicing RPC
> requests, when block encoding is enabled, comes from
> BufferedDataBlockEncoder$SeekerState.<init>, 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.
