Anticompaction Question

Hello,

If incremental repairs are enabled, there is logic in every compaction strategy to make sure not to mix repaired and unrepaired SS Tables.

Does this mean if some SS Table files are repaired and some aren't and incremental repairs don't work reliably, the unrepaired tables will never get compacted into repaired ones ?

Thanks !

Hi Anubhav,

According to the Datastax documentation here
<http://www.datastax.com/dev/blog/more-efficient-repairs>, after the
anti-compaction process splits the ranges to repaired and un-repaired
SSTables, they are compacted in their own separate pools.

Regards,
Rajath
