Subject Re: Table scan/count hangs on particular table
Date Tue, 22 Dec 2015 05:36:49 GMT
You can narrow the scope of search by issuing scan with start row of region
N and stop row of region N+1 (repeat for regions with #rows > 0).
Suppose you find that scanning region R hangs. You can capture stack trace
on the server which hosts R and pastebin it.
