> On startup, already built SAI indexes are made queryable in two distinct
> ways. The first is asynchronous, as the secondary index initialization task
> is run. (SAI automatically repairs local column indexes that are incomplete
> and marks them queryable when this finishes.) The second is synchronous, in
> what are called "pre-join tasks". These run before a node is marked NORMAL
> after bootstrap. The problem with this design is that, on a node that is
> already NORMAL/bootstrapped, we don't actually attempt to make already built
> indexes queryable before the node starts accepting requests. The problem is
> transient, but it should also be easy to address, at least for SAI, by
> synchronously validating the index when the initialization task is requested
> and marking it queryable, if possible, before CFS initialization finishes.
