> We have only data size and heap overhead being tracked globally. Off heap
> memstore works with off heap backed MSLAB pool. But a cell, when added to
> memstore, not always getting copied to MSLAB. Append/Increment ops doing an
> upsert, dont use MSLAB. Also based on the Cell size, we sometimes avoid
> MSLAB copy. But now we track these cell data size also under the global
> memstore data size which indicated off heap size in case of off heap
> memstore. For global checks for flushes (against lower/upper watermark
> levels), we check this size against max off heap memstore size. We do check
> heap overhead against global heap memstore size (Defaults to 40% of xmx) But
> for such cells the data size also should be accounted under the heap overhead.
