+1 LGTM, ran a full build with contrib-check and unit tests, and tried
UpdateRecord and QueryRecord with various schemas, Readers/Writers, with/out
Expression Language, etc. I didn't do any explicit performance testing
(metrics, e.g.) but it did seem to perform faster. Thanks for the
improvements! Merging to master---
