Hello, I’ve recently updated percona server from 5.7 to 8.0, It’s too bad to hear that TokuDB will be deprecated as storage engine. What is the main reason ? Should I change the storage engine to MyRocks ?

I’m not qualified to speak on behalf of Percona, but this announcement surprised me also. I strongly think Percona does not have the skillset or manpower to finish the remaining open topics from TokuDB or bring it to next level.

I don’t know.  
I am using tokudb for a Time Series Database with 5000Million registers  
Will Rockdb support that ?.

[Lotia](https://percona.vanillacommunities.com/profile/x/x/24252) I have a similar use case and tried to play with RocksDB. Compared to TokuDB, where a simple “alter table… engine=TokuDB” was all I needed, with RocksDB I encountered problems over problems, to the extend I was even considering diving deep in MySQL and fix TokuDB myself. Have you played with RocksDB until now? If yes, do you have some suggestions regarding good settings for timeseries?
