Hey Chuck. The CONCURRENT option is actually there although it's not documented (and I suspect not officially supported). All it really does it not lock the file which doesn't happen until the select is completed anyway. One would have to make sure no updates were being made to the file until the select finishes or the index build may not be complete and accurate or may include entries for deleted records. At this point not taking a file lock on the data file seems less useful as the index file is going to be cleared prior to population and the population doesn't really take all that long in comparison to the select in most cases. In any event seems very messy to me.
Traditional relational databases have the option to build/rebuild indexes while the table is in use. In the end it seems to me that Rocket needs to come up with a completely new strategy for building/rebuilding an index.

And then you can write your own update program to back-populate the index w/o having to do a build at all. But if your & my connivings are true, then why doesn't RocketSQ give that to us as a concurrent build option? A few years ago they (as IBM) declared that 7x24 uptime was a big goal for U2.
