>
> 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).
