GitHub user zuyu opened a pull request:
https://github.com/apache/incubator-quickstep/pull/151
Marked SingleNodeQuery for Insertions.
This PR avoids the following incorrect situation:
1. An insert query has executed on Node 0, so the affected block is in the
buffer pool.
1. Another insert query on the same relation as above is supposed to be
scheduled on Node 1, which will pull the block from Node 0, and do the
insertion.
1. A select query on the same relation may be scheduled on Node 0, but
will miss the tuples inserted on Node 1.
