To accelerate queries in interactive analysis scenarios, we recommend that you upgrade MaxCompute Lightning to Hologres. For more information, see Upgrade MaxCompute Lightning to Hologres. Hologres is compatible with the Postgres protocol and provides more stable query performance and more features than MaxCompute Lightning. You can use Hologres without the need to modify your application. You can join the DingTalk group Lightning Migration Support for consultation. The group ID is 35028911.
Note You can also use the MaxCompute Query Acceleration (MCQA) feature instead of MaxCompute Lightning to process your business. For more information about MCQA, see Overview.
