> The Compaction heartbeater should be improved the following ways:
> * The metastore clients should be reused between heartbeats and closed only
> at the end, when the transaction ends
> * Instead of having a dedicated heartbeater thread for each Compaction
> transaction, there should be shared a heartbeater executor where the
> heartbeat tasks can be scheduled/submitted.
