Andrew Purtell updated HBASE-10063:
-----------------------------------
Description: In SecureWALCellCodec#EncryptedKvEncoder#write we get the IV
for the entry from the secure RNG. This can be a heavyweight operation if not
using an accelerated RNG. Consider something lighter weight. One option could
be to create a random IV only once, store it in the header, and then increment
it per cell. (was: In SecureWALCellCodec#EncryptedKvEncoder#write we get the

increment it per cell. Correct decryption will depend on being able to
correctly count entries even if skipping or rewinding.)
