Request a new category for transaction

Discussion about distributed transaction, focus on transactions in TiKV and TiKV clients (including TiDB, which use TiKV go-client), but discuss academic work and other implementations too.

cc @andylokandy @sticnarf please attach other information I missed or example posts in your mind about transaction category.

I personally don’t see the necessity. Maybe just discussing in tikv related category is enough?
There may be situations when we need to discuss something related to both transaction and tikv, and I am afraid that this may lead to distractions, because of too many categories.
IMHO, we can leave it and see.
