As far as I can see, SYSCS_INPLACE_COMPRESS_TABLE does not update the
index statistics. I couldn't find anything in the in-place compress code
that attempted to update the statistics, and it didn't appear to have
updated them when I monitored the CREATIONTIMESTAMP column in
SYS.SYSSTATISTICS.
I think much of the documentation about index statistics was written
before in-place compress was implemented, which is probably why the docs
are unclear. Could you please file a JIRA issue and point to the
sections that you found unclear? Thanks.
Hmm just noticed this in the docs for the related
SYSCS_UTIL.SYSCS_COMPRESS_TABLE procedure:
"The SYSCS_UTIL.SYSCS_COMPRESS_TABLE system procedure updates statistics
on all indexes as part of the index rebuilding process."
But no mention of that (either way) for
SYSCS_UTIL.SYSCS_INPLACE_COMPRESS_TABLE
