Andrew Purtell commented on HBASE-10077:
----------------------------------------

bq. So one Mutation write will involve write to 2 WALs.  

Maybe. If the edit spans families and the families are partitioned to different WALs. 

bq. Atomicity for 2 WAL writes (?)

Most likely not.

The thing about security is, as soon as you need it, you must accept something else that sucks :-), be it a performance drop, or this.

> HBASE-7544 introduces WAL encryption to prevent the leakage of protected data to disk by way of WAL files. However it is currently enabled globally for the regionserver. Encryption of WAL entries should depend on whether or not an entry in the WAL is to be stored within an encrypted column family.
