[GitHub] [iotdb] LebronAl opened a new pull request #2222: [Distributed] fix session cache leader interface and docs

LebronAl opened a new pull request #2222:
URL: https://github.com/apache/iotdb/pull/2222


   As cluster_new is  merged into master, It is better not to open the leader cache by default and give an parameter interface for distributed IoTDB, otherwise it will cause unnecessary performance waste to the stand-alone IoTDB.

Review comment:
       Testonly's anonation is currently in the server module. The session module does not currently have a dependency on the server module, so I don't think it would be appropriate to introduce a dependency just for this purpose. As for creating a new testonly anotation in the session module, I think it's a bit redundant because it's the only one we've used so far. But if you think it's worth creating a new anonation in the Session Module, I'll do it. What your opinion?
