I understand that indexes are CFs. But the compaction stats says it's
building the
index, not compacting the corresponding CF. Either that's an ambiguous
diagnostic,
or indeed something is not right with my rig as of late.

Well, the since the secondary indexes are themselves
column families they too are compacted along with everything else.

Thanks Jake. Then I am definitely seeing weirdness, as there are
tons of
"pending tasks" in compaction stats, and tons of index files
created in the
data directory. Plus it does tell me that it is building the
secondary index,
and that seems to be happening at an amazingly glacial pace.
I have 2 CFs there, with multiple secondary indexes. I'll try
to compact the CF one by one, reboot and see if that helps.

No, the indexes are not rebuilt every compaction. Only if you
manually rebuild or bootstrap a new node does it use compaction
manager to rebuild.

Thanks Aaaron. Just to be clear, every time I do a compaction,
I rebuild all indexes from scratch. Right?

Yes secondary index builds are done via the compaction manager.

I noticed that "nodetool compactionstats" shows the
building of the secondary index while
I initiate compaction. Is this to be expected? Cassandra
