bq.Hello, did it go well ?
Yes, thanks for the patch and sorry that I forgot to include the link to the CI
jobs in my previous comment:

The CI looks good relative to upstream (there are some dtest failures also
present in trunk), so I've committed to 3.X in
{{afbc2e8502a8a8d1d6a319017dfc3c2a45bebaca}} and merged to trunk.
bq.Another sensible optimization will be CASSANDRA-12962
I'm sure someone will take a look at that as soon as they have chance. In the
meantime, I quickly glanced at the ticket and I'm afraid I don't really
understand the problem you're describing. Perhaps the description could use a
little work to make it a bit clearer?

> Project: Cassandra
> Issue Type: Improvement
> Components: CQL

> Fix For: 4.0, 3.12

>
> During startup, each existing index is opened and marked as built by adding
> an entry in "IndexInfo" and forcing a flush. Because of that we end up
> flushing one sstable per index. On systems on HDD this can take minutes for
> nothing.
> Thw following patch allows to avoid creating useless new sstables if the
> index was already marked as built and will greatly reduce the startup time
> (and improve availability during restarts).
