## Proposed changes Issue Number: close #xxx [Opt] (multi-catalog) Opt split assignment to resolve uneven distribution. Referring to the implementation of Trino, - Local node soft affinity optimization. Prefer local replication node. - Remote split will use the consistent hash algorithm is used when the file cache is turned on, and because of the possible unevenness of the consistent hash, the split is re-adjusted so that the maximum and minimum split numbers of hosts differ by at most `max_split_num_variance` split. - Remote split will use the random algorithm is used when the file cache is turned off. ## Further comments If this is a relatively large or complex change, kick off the discussion at [[email protected]](mailto:[email protected]) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
