kalyan kumar kalvagadda commented on SENTRY-2423:
-------------------------------------------------
Currently we do not provide and strategy explicitly, so datanucleus uses
"native" strategy for all the auto generated columns. This is what happens
when "native" is used.
If there is any sequence provided, datanucleus would use sequence as strategy
if the the understand database also supports sequences, otherwise datanucleus
uses increment strategy.
> Increase the allocation size for auto-increment of id's for Snapshot tables.
