> For non-partitioned tables, stats detail should be present in table level,
> e.g
> {noformat}
> COLUMN_STATS_ACCURATE={"BASIC_STATS":"true","COLUMN_STATS":{"d_current_day":"true"... }}
>   {noformat}
> For partitioned tables, stats detail should be present in partition level,
> {noformat}
> store_sales(ss_sold_date_sk=2451819)
> {totalSize=0, numRows=0, rawDataSize=0, COLUMN_STATS_ACCURATE={"BASIC_STATS":"true","COLUMN_STATS":{"ss_addr_sk":"true"....}}
>  
>  {noformat}
> When stats populated are already accurate, {{analyze table tn compute statistics for columns}} should skip launching the job.
>  
> For ACID tables, stats are auto computed and it can skip computing stats again when stats are accurate.
