## Description Current distinctCountHLL hard coded Hyperloglo object's `log2m` value to 8, which prevents users from tuning the results accuracy vs query speed. This PR extends `distinctCountHLL` to take `log2m` value as the second argument. Adding a cluster config to allow users to customize default log2m value for query. ## Release Notes * Support customized accuracy for `distinctCountHLL`, `distinctCountHLLMV` functions by adding `log2m` value as the second parameter in the function. * Adding cluster config: `default.hyperloglog.log2m` to allow user set default `log2m` value. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
