I have a problem with a query that consumes a long time.
The query' execution plan is :
EXPLAIN ANALYZE SELECT x."HistoryId", x."SlaDefinition" FROM "T_CMN_SLAHISTORY" AS x WHERE x."DefinitionId" = '302'; QUERY PLAN ----------------------------------------------------------------------------------------------------------------------------------------------------------- Bitmap Heap Scan on "T_CMN_SLAHISTORY" x (cost=2144.77..35086.42 rows=139012 width=8) (actual time=58.806..116.874 rows=135498 loops=1) Recheck Cond: ("DefinitionId" = 302) Heap Blocks: exact=2175 -> Bitmap Index Scan on "Index-20180712-192739" (cost=0.00..2110.02 rows=139012 width=0) (actual time=57.043..57.045 rows=135498 loops=1) Index Cond: ("DefinitionId" = 302) Planning Time: 11.132 ms Execution Time: 120.320 ms
But, the query execution time was 43min 11seconds in the morning in pgbadger report. I don't understand why the query is taking so long. Can you guide me?
