Subject [jira] [Commented] (ACCUMULO-958) Support pluggable encryption in walogs
Date Sat, 26 Jan 2013 00:51:12 GMT

Josh Elser commented on ACCUMULO-958:
-------------------------------------

I don't think there's a single answer to that, but it depends on the complexity of the feature.
I'm being snarky because after the feature freeze was extended a week, we finally see the
patch. Your point about it being in X time earlier is what I'm trying to point out.

We still have the ability to review this even after the feature freeze happens, it's just
frustrating from my point of view in generating the best 1.5.0 candidate possible (we tend
to go through x.y.0 releases pretty darn quick).

> There are some cases where users want encryption at rest for the walogs. It should be
fairly trivial to implement it in such a way to insert a CipherOutputStream into the data
path (defaulting to using a NullCipher) and then making the Cipher pluggable to users can
insert the appropriate mechanisms for their use case.
> This also means swapping in CipherInputStream and putting in a check to make sure the
Cipher type's match at read and write time. Possibly a versioning mechanism so people can
migrate Ciphers.
