> Compaction output directories' writeIds only reflect the writeIds of the deltas it compacts, and not the max write id of the table
> Example:
> Pre-compaction...
> {code:java}
> Partition p=1 contains:
> delta_1_1
> delta_2_2
> partition p=2 contains
> delta_3_3
> delta_4_4
> {code}
> After minor compaction...
> {code:java}
> Partition p=1 contains:
> delta_1_2
> partition p=2 contains
> delta_3_4
> {code}
> AFAIK there are no unit tests that reflect this.
> TestTxnCommands2#testFullACIDAbortWithManyPartitions is a good template to start with.
