[TRAFODION-1867] Allow parallel plans for non-partitioned tables in Uâ¦
â¦PD STATS.
The problem is for large non-partitioned tables, UPDATE STATS will do a
series of SELECTs to compute statistics for sets of columns. The plans for
these SELECTs are presently forced to be serial for non-partitioned tables as a
workaround for a long-ago compiler bug which seems to have been fixed. It's
time to remove this workaround and thereby speed up UPDATE STATS.
