> OpenJpa use allocationSize parameter on NativeJDBCSeq to set the sequence
> cache value.
> But one "JSR 220: Enterprise JavaBeansTM,Version 3.0" , the allocationSize is
> : "The amount to increment by when allocating sequence
> numbers from the sequence."
> Allocating is used to limit the number of access to the sequence or table not
> to set the sequence cache value !
> If allocationSize=50, the sequence need to be call one time on each 50 call
> on AbstractJDBCSeq.next().
> 1 call on AbstractJDBCSeq.next(). call the sequence or table
> 2 call : return previous value + 1;
> 3 call : return previous value + 2;
> ...
> 51 call :re-call the sequence
> 52 return previous value + 1
> ...
