dhatchayani opened a new pull request #3144: [CARBONDATA-3313] count(*) is not invalidating the invalid segments cache
URL: https://github.com/apache/carbondata/pull/3144
 
 
   **Problem:**
   If any segment is deleted the next query has to clear/invalidate the datamap cache for those invalid segments. But count(*) has not considered the invalid segments to clear the datamap cache.
   
   **Solution:**
   In count(*) flow, before clearing the datamap cache, check and add the invalid segments of that table.
