  You have migrated from Teradata to Snowflake, one of the main issues which you faced in the old system is with the MPI system data. The MPI data is sent by the source system daily at 01:00 AM and the ETL Process will take around 5-6 hours and loads the data into the target tables between 06:00 AM to 07:00 AM. After the ETL process is complete no other process will modify the data in these tables until the business users check and confirm the Ledger Transactions. After the users confirm, the Indicators in the target table are updated and data will be loaded to the downstream tables. The Issue which is faced by the business users while accessing the data in Teradata is, each user has to wait for 01-02 hours to get the required General Ledger Stats, and sometimes when multiple queries are executed the CPU I/O usage was high. Business users want to get the query results immediately as these are static SQL’s which they use on daily basis. How these issues can be fixed in the newly migrated Snowflake database?
