[DISCUSS] Drop In-memory MetaStore in favour of H2

[Dmitri Bourlatchkov]

Hi All,

Given that it is possible to run EclipseLink with H2 in memory, is there
value in keeping a separate in-memory MetaStore implementation?

My main concern is that the plain in-memory MetaStore is significantly
different from the EclipseLink metastore and might deviate in behaviour.
With that in mind and given that the plain in-memory impl. is not suitable
for production use cases, is it worth keeping it? WDYT?

Thanks,
Dmitri.
