Thanks Dmitry!

At very begin we did not specify the copyOnRead; I remember in another thread you suggest
us to set to false to save memory? 

JavaDoc: "Also if this flag is set copies are created for values passed to {@link CacheInterceptor}
and to {@link CacheEntryProcessor}."

Also if set this flag to true will the read have to read from off-heap? will this meaning
be slower? 

if Reside in heap queue and more than batchSize,  will those data be lost before DB recover?

Thanks for your time!

Hi Aaron,
If data could not be stored to DB, they will reside in heap queue, but no
more than batchSize.
I see you set copyOnRead to false, this property forces ignite to keep
object on-heap, why do you need it?
