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
