Hello Igniters,
I want to start voting on removing the public API (and eventually all
unused parts) related to the MVCC feature.
This topic has already been discussed many times (at least, [1], [2]) and
the community has agreed the feature implementation must be reapproached,
because using coordinator node for transactions ordering and 2pc protocol
is slow by design and will not scale well. [3]
Moreover, the current implementation has critical issues [4], not supported
by the community, and not well tested at all.
Removing the public API first will allow us to clean up the code later step
by step without rushing and keep intact useful improvements that are
already in use or can be reused for other parts in the future.
For instance, partition counters implementation is already adapted to fix
tx caches protocol issues [5].
The future of MVCC is unclear for now, but, definitely, this feature is
useful for a lot of user scenarios and can be scheduled for later Ignite
versions.
Also, the MVCC feature is in an experimental state, so it can be modified
in any way, I think.
+1 - to accept removing MVVC feature from public API
0 - don't care either way
-1 - do not accept removing API (explain why)
The vote will hold for 7 days and will end on Wednesday, December 16th at
19:00 UTC:
