Description:
We have installed a distribuited deployment (Pattern 2), with two Analytics Worker instances.
Everything seems working fine but, database side, the following error occurrs periodically:

2021-03-24 14:17:07 UTC [24783-14] xxx@WSO2AM_STATS_DB STATEMENT:  SELECT 1 FROM AM_USAGE_UPLOADED_FILES
2021-03-24 14:17:07 UTC [24787-7] xxx@WSO2AM_STATS_DB ERROR:  relation "am_usage_uploaded_files" does not exist at character 15

Below the database configurations in the deployment.yaml file of the Analytics Worker:
