I confirmed with the author that the change
no_io = falsemade in #211 was not intended as the PR description suggested.If
no_iois set to true,TableCachewould not load the table and add it to the cache, when the table does not exist in the cache already, instead, the caller (in this case,Versionwhich is then called by compaction) is responsible to load the table properties without affecting the cache. Since compaction is an one-off operation (from SST's perspective), it makes more sense to setno_ioto true here.
