MaxCompute Lightning was an interactive query service which complies with the PostgreSQL protocol and syntax.
Due to the architecture upgradation, the entry point of MaxCompute Lightning (Endpoint starts with lightning.cn-*) will be terminated at 00:00 (GMT+8) on December 31, 2021. The existing MaxCompute Lightning service will be extended for another year which will not be affected until 00:00 (GMT+8) , December 31, 2022.
We strongly recommend our Lightning users upgrade their existing Lightning service to Hologres which provides more stable query performance and features. For more information, please refer to Upgrade MaxCompute Lightning to Hologres.
