Gagan Goel 86fb66365c 1. Set 1M as the threshold on the number of records to flush the cache.
2. Set 100k as the batch size when flushing records into ColumnStore, i.e.,
a flush of 1M records will be performed in 10 batches, each being 100k.

3. For INSERT ... SELECT on the cache, use the default insertion method of cpimport.
