Summary0043083: Webpos Login, Initial validations makes inefficient query to application payments
DescriptionThe initial validation in webpos makes a bad performance query to applications payments, doing a sequential scan on obretco_cmevents for each payment.

with high concurrency and many obretco_cmevents, the read in memory/disk is very high.

This is the explain plan:

Steps To ReproduceLogin in the webpos in a terminal with many payments and cash management Events.
The query launched is the folloging:

select obpos_app_0_.* from OBPOS_APP_PAYMENT obpos_app_0_ where obpos_app_0_.Obpos_Applications_ID='XX' and (obpos_app_0_.FIN_Financial_Account_ID is not null) and (exists (select 1 from OBRETCO_CMEvents obretco_ca1_ where obretco_ca1_.FIN_Financial_Account_ID=obpos_app_0_.FIN_Financial_Account_ID)) and (obpos_app_0_.AD_Org_ID in ('0' , 'XX')) and (obpos_app_0_.AD_Client_ID in ('XX' , '0')) and obpos_app_0_.Isactive='Y'
Proposed SolutionCreate an index in obretco_cmevents for the fin_financial_account_id in order to evict the seq scan.

CREATE INDEX <index-name> ON obretco_cmevents (fin_financial_account_id)

Fixes issue 43083: Improved performance in query on Webpos Login

The initial validation in webpos was making a bad performance query to applications
payments, doing a sequential scan on obretco_cmevents for each payment.

To fix that, was added a new index on the FIN_FINANCIAL_ACCOUNT_ID column of OBRETCO_CMEVENTS
table to improves the execution of queries.
