Number of Rows 2. Number of files 3. Size in Bytes If table/partition is big, the operation would take time since it will open all files and scan all data. It would be nice to support fast operation to gather statistics which doesn't require to open all files: 1. Number of files 2. Size in Bytes Potential syntax is ANALYZE TABLE tablename [PARTITION(partcol1[=val1], partcol2[=val2], ...)] COMPUTE STATISTICS [noscan]; In the future, all statistics without scan can be retrieved via this optional parameter. -- This message is automatically generated by JIRA.
