Currently hbase use memstore to store the information before flushing it to hFILE.

Is there any way that i can use the Memstore to write my own key value pair and then it will get flush into HFILE. Mean to say can we use MemStore to use it in our own way.

Thanks

I don’t think this is in the control of the HBase client. If there’s
anything that might give you some control over this (and I’m not even
sure it does) it’s HBase coprocessors. There’s a preFlush() method on
the RegionObserver interface, but I’m not sure how much it can alter
what’s being flushed.

This does not belong on this list (this is AsyncHBase, a client of HBase, and you are asking about a serverside facility).
