Anastasia Braginsky commented on HBASE-16438:
---------------------------------------------

bq. Chance of getting GCed might be bit more when chunk is actually removed 
from Map (No refs to it at all) than still referring with one SoftRef.

I am sure you'll see no difference. Think what the chances are that all the 
cells in the (big sized) chunk are replaced till it is flushed in memory.

bq. So shall we do that also in this JIRA or should we just finish the patch in 
the current state and go with a new JIRA to solve the GC problem that we may 
face?

As we are designing the Creator now I think it should be written appropriately 
from the beginning. I mean with "convertible" references in the map, if we 
choose this way. Why to write it anyhow and then rewrite it?

> Create a cell type so that chunk id is embedded in it

> For CellChunkMap we may need a cell such that the chunk out of which it was 
> created, the id of the chunk be embedded in it so that when doing flattening 
> we can use the chunk id as a meta data. More details will follow once the 
> initial tasks are completed. 
> Why we need to embed the chunkid in the Cell is described by [~anastas] in 
> this remark over in parent issue
