Percona-TokuDB used to support NOAR (No Affected Rows) fast upserts ([url][https://www.percona.com/blog/2013/02/12/fast-updates-with-tokudb/[/url]](https://www.percona.com/blog/2013/02/12/fast-updates-with-tokudb/%5B/url%5D) [url][https://www.percona.com/blog/2013/03/28/tokudb-fast-update-benchmark/[/url]](https://www.percona.com/blog/2013/03/28/tokudb-fast-update-benchmark/%5B/url%5D))

It is already a feature request to re-enable it on the modern Percona Server and there are already branches ready for merging! ([url][https://jira.percona.com/browse/TDB-63[/url]](https://jira.percona.com/browse/TDB-63%5B/url%5D) [url][https://tokutek.atlassian.net/browse/DB-871[/url]](https://tokutek.atlassian.net/browse/DB-871%5B/url%5D))

Please please please get this feature back in! Users could really use it!

I am seriously regretting going from an old manual tokudb patch to using Percona Server because upsert performance has tanked. NOAR has a really big impact on upsert-heavy workloads.
