> 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.
