# Which Problems Are Solved Zitadel currently uses 3 database pool, 1 for queries, 1 for pushing events and 1 for scheduled projection updates. This defeats the purpose of a connection pool which already handles multiple connections. During load tests we found that the current structure of connection pools consumes a lot of database resources. The resource usage dropped after we reduced the amount of database pools to 1 because existing connections can be used more efficiently. # How the Problems Are Solved Removed logic to handle multiple connection pools and use a single one. # Additional Changes none # Additional Context part of https://github.com/zitadel/zitadel/issues/8352
