> Currently, during region location lookups, the meta is scanned and for this
> the scanner submits a request to the thread pool of the table in question.
> Sometimes, it might happen that many scan requests are simultaneously
> submitted on the table - let's say 256, and this is the max size of the
> thread pool. Each of these scan requests would in turn submit meta scan
> requests on the same thread pool, but they will be in the queue. The meta
> scans will not happen and the original table scans would lock up. The meta
> scans should use a different thread pool.
