Flushing memstore could happen at any time and should not have visible 
performance impact. Why you want to avoid doing that?

Hi community:

Currently our environment will import about 200G into HBase each day.
These datas are cross six tables which table has about 100 Regions. We use 
HBase bulk tools completed these import tasks. We investigate HBase source code 
found when bulk loading task happen, HRegionServer will at firstly flush 
memstore according to each HRegion, We want to turn off assignSeqIds avoid each 
HRegion to force flush memstore. But We don't know these adverse impact if we 
do. Please help me to point out these impacts. Thanks
