1) First, we lock myid.CB9019388E1 for access, we lock ICDW_CB_PRSN_T.acct in view ICDW_CB_PRSN_V.DDM_FCT_TXN for access, we lock ICDW_CB_PRSN_T.txn in view ICDW_CB_PRSN_V.DDM_FCT_TXN for access, we lock ICDW_CB_PRSN_T.DDM_DIM_ACCT_DTL in view ICDW_CB_PRSN_V.DDM_DIM_ACCT_DTL for access, and we lock ICDW_CB_PRSN_T.DDM_DIM_TXN in view ICDW_CB_PRSN_V.DDM_DIM_TXN for access.## Heading ## 2) Next, we do an all-AMPs SUM step to aggregate from myid.CB9019388E1 by way of an all-rows scan with a condition of ("NOT (myid.CB9019388E1.ACCT_NB IS NULL)") , grouping by field1 ( myid.CB9019388E1.ACCT_NB). Aggregate Intermediate Results are computed locally, then placed in Spool 3. The size of Spool 3 is estimated with low confidence to be 3,335 rows (1,377,355 bytes). The estimated time for this step is 0.01 seconds. 3) We do an all-AMPs RETRIEVE step from Spool 3 (Last Use) by way of an all-rows scan into Spool 1 (used to materialize view, derived table, table function or table operator D) (all_amps) (compressed columns allowed), which is built locally on the AMPs. The size of Spool 1 is estimated with low confidence to be 3,335 rows ( 737,035 bytes). The estimated time for this step is 0.01 seconds. 4) We execute the following steps in parallel. 1) We do an all-AMPs RETRIEVE step from Spool 1 (Last Use) by way of an all-rows scan with a condition of ("NOT (D.ACCT_NB IS NULL)") into Spool 6 (all_amps) (compressed columns allowed), which is duplicated on all AMPs. The size of Spool 6 is estimated with low confidence to be 4,942,470 rows ( 1,057,688,580 bytes). The estimated time for this step is 0.37 seconds. 2) We do an all-AMPs RETRIEVE step from ICDW_CB_PRSN_T.DDM_DIM_ACCT_DTL in view ICDW_CB_PRSN_V.DDM_DIM_ACCT_DTL by way of an all-rows scan with no residual conditions into Spool 7 (all_amps) (compressed columns allowed), which is built locally on the AMPs. The size of Spool 7 is estimated with high confidence to be 176,214,248 rows (7,400,998,416 bytes). The estimated time for this step is 0.73 seconds. 5) We do an all-AMPs JOIN step from Spool 6 (Last Use) by way of an all-rows scan, which is joined to Spool 7 (Last Use) by way of an all-rows scan. Spool 6 and Spool 7 are joined using a single partition hash join, with a join condition of ( "(TRANSLATE((ACCT_NB )USING LATIN_TO_UNICODE)(BIGINT, FORMAT '-(19)9'))= (TRANSLATE((ACCT_NB )USING LATIN_TO_UNICODE)(BIGINT, FORMAT '-(19)9'))"). The result goes into Spool 8 (all_amps) (compressed columns allowed), which is built locally on the AMPs. Then we do a SORT to order Spool 8 by the hash code of ( ICDW_CB_PRSN_T.DDM_DIM_ACCT_DTL.ACCT_DIM_NB). The size of Spool 8 is estimated with low confidence to be 3,336 rows (136,776 bytes). The estimated time for this step is 0.11 seconds. 6) We do an all-AMPs JOIN step from Spool 8 (Last Use) by way of a RowHash match scan, which is joined to 74 partitions of ICDW_CB_PRSN_T.acct in view ICDW_CB_PRSN_V.DDM_FCT_TXN by way of a RowHash match scan with a condition of ("(ICDW_CB_PRSN_T.acct in view ICDW_CB_PRSN_V.DDM_FCT_TXN.TIME_DIM_NB >= DATE '2013-01-01') AND (ICDW_CB_PRSN_T.acct.TIME_DIM_NB <= DATE '2019-01-31')"). Spool 8 and ICDW_CB_PRSN_T.acct are joined using a sliding-window merge join, with a join condition of ( "ICDW_CB_PRSN_T.acct.ACCT_DIM_NB = ACCT_DIM_NB"). The result goes into Spool 9 (all_amps) (compressed columns allowed), which is built locally on the AMPs. The size of Spool 9 is estimated with low confidence to be 73,453 rows (3,893,009 bytes). The estimated time for this step is 0.33 seconds. 7) We execute the following steps in parallel. 1) We do an all-AMPs JOIN step from Spool 9 (Last Use) by way of an all-rows scan, which is joined to rows (DAY_TIME_DIM_NB) values (DATE '2019-01-31'), (DATE '2019-01-30'), (DATE '2019-01-29'), (DATE '2019-01-28') Spool 9 and rows are joined using a product join, with a join condition of ("(1=1)"). The result goes into Spool 10 (all_amps) (compressed columns allowed), which is redistributed by the rowkey of ( ICDW_CB_PRSN_T.acct.TIME_DIM_NB, ICDW_CB_PRSN_T.DDM_DIM_ACCT_DTL.ACCT_DIM_NB, DAY_TIME_DIM_NB) to all AMPs. Then we do a SORT to partition Spool 10 by rowkey. The size of Spool 10 is estimated with low confidence to be 163,212,566 rows (9,303,116,262 bytes). The estimated time for this step is 1.49 seconds. 2) We do an all-AMPs RETRIEVE step from ICDW_CB_PRSN_T.DDM_DIM_TXN in view ICDW_CB_PRSN_V.DDM_DIM_TXN by way of an all-rows scan with a condition of ( "ICDW_CB_PRSN_T.DDM_DIM_TXN in view ICDW_CB_PRSN_V.DDM_DIM_TXN.CS_TXN_CD IN ('387 ', '388 ','389 ','390 ')") into Spool 11 (all_amps) (compressed columns allowed), which is duplicated on all AMPs. Then we do a SORT to order Spool 11 by the hash code of ( ICDW_CB_PRSN_T.DDM_DIM_TXN.TXN_DIM_NB). The size of Spool 11 is estimated with low confidence to be 145,236 rows ( 3,630,900 bytes). The estimated time for this step is 0.00 seconds. 8) We do an all-AMPs JOIN step from 2222 partitions of ICDW_CB_PRSN_T.txn in view ICDW_CB_PRSN_V.DDM_FCT_TXN by way of a RowHash match scan with a condition of ("(ICDW_CB_PRSN_T.txn in view ICDW_CB_PRSN_V.DDM_FCT_TXN.TIME_DIM_NB >= DATE '2013-01-01') AND (((INDEX(UPPER((ICDW_CB_PRSN_T.txn in view ICDW_CB_PRSN_V.DDM_FCT_TXN.TXN_DESCRIPTION )),'REVERSAL:'))= 0) AND (ICDW_CB_PRSN_T.txn in view ICDW_CB_PRSN_V.DDM_FCT_TXN.TIME_DIM_NB <= DATE '2019-01-31'))"), which is joined to Spool 10 (Last Use) by way of a RowHash match scan. ICDW_CB_PRSN_T.txn and Spool 10 are joined using a rowkey-based merge join, with a join condition of ("(ACCT_DIM_NB = ICDW_CB_PRSN_T.txn.ACCT_DIM_NB) AND ((TIME_DIM_NB = ICDW_CB_PRSN_T.txn.TIME_DIM_NB) AND ((TIME_DIM_NB >= ICDW_CB_PRSN_T.txn.DAY_TIME_DIM_NB) AND ((ICDW_CB_PRSN_T.txn.ACCT_DIM_NB = ACCT_DIM_NB) AND (DAY_TIME_DIM_NB = ICDW_CB_PRSN_T.txn.DAY_TIME_DIM_NB ))))"). The input table ICDW_CB_PRSN_T.txn will not be cached in memory, but it is eligible for synchronized scanning. The result goes into Spool 12 (all_amps) (compressed columns allowed), which is built locally on the AMPs. Then we do a SORT to order Spool 12 by the hash code of (ICDW_CB_PRSN_T.txn.TXN_DIM_NB). The size of Spool 12 is estimated with no confidence to be 1,131,190 rows ( 211,532,530 bytes). The estimated time for this step is 1 minute and 44 seconds. 9) We do an all-AMPs JOIN step from Spool 11 (Last Use) by way of a RowHash match scan, which is joined to Spool 12 (Last Use) by way of a RowHash match scan. Spool 11 and Spool 12 are joined using a merge join, with a join condition of ("TXN_DIM_NB = TXN_DIM_NB"). The result goes into Spool 5 (group_amps), which is built locally on the AMPs. The size of Spool 5 is estimated with no confidence to be 35,048 rows (6,904,456 bytes). The estimated time for this step is 0.01 seconds. 10) Finally, we send out an END TRANSACTION step to all AMPs involved in processing the request. -> The contents of Spool 5 are sent back to the user as the result of statement 1. The total estimated time is 1 minute and 47 seconds.
