> > Now much we can gain, the metadata file group initialization should be light-weight enough right? > > Yes, now usually the fileGroup Count will not be very large, but it will be large in the case of record level index. Can be optimized for parallel execution The initialization method will not be called often, and the number of fileGroups in the metaTable is relatively small, but in the record level index scenario, the large table will have thousands of filegroups, and the single-threaded creation on the driver side is very slow, in general, this method is not often called and has little impact on the small metaTable, and the benefits are much greater than single-thread initialization in the large filegroup scenario -- This is an automated message from the Apache Git Service.
