For `pull_cdc_kafka_integration_light` and\u000a`pull_cdc_mysql_integration_light`, the pipelines were refactored to:\u000a - Use `agent none` at the pipeline level.\u000a- Merge the `Checkout` and `prepare` stages into a single `Checkout &\u000aPrepare` stage with its own agent.\u000a This ensures agents are only allocated when required.\u000a\u000a2. For `pull_cdc_kafka_integration_heavy`,\u000a`pull_cdc_mysql_integration_heavy`, `pull_cdc_pulsar_integration_light`,\u000a`pull_cdc_storage_integration_heavy`, and\u000a`pull_cdc_storage_integration_light`, the redundant stage-level\u000a`timeout` option was removed from the `Checkout & Prepare` stage. This\u000acentralizes timeout management at the global pipeline level.\u000a\u000a**Next-gen Pipelines:**\u000a\u000aAll `next_gen` integration test pipelines were refactored to:\u000a- Use `agent none` at the pipeline level.\u000a- Merge the `Checkout` and `prepare` stages into a single `Checkout &\u000aPrepare` stage with its own agent.\u000a\u000aThis aligns the `next_gen` pipelines with the resource-saving standards\u000aof the classic pipelines, ensuring that agents are only allocated when\u000arequired. This reduces overall resource consumption and improves\u000amaintainability.\u000a\u000a## Tests\u000a\u000a- [x]\u000a[pull_cdc_kafka_integration_light](https://prow.tidb.net/jenkins/job/pingcap/job/ticdc/job/pull_cdc_kafka_integration_light/188/)\u000a- [x]\u000a[pull_cdc_mysql_integration_light](https://prow.tidb.net/jenkins/job/pingcap/job/ticdc/job/pull_cdc_mysql_integration_light/227/)\u000a- [ ]\u000a[pull_cdc_pulsar_integration_light](https://prow.tidb.net/jenkins/job/pingcap/job/ticdc/job/pull_cdc_pulsar_integration_light/177)\u000a- [x]\u000a[pull_cdc_storage_integration_light](https://prow.tidb.net/jenkins/job/pingcap/job/ticdc/job/pull_cdc_storage_integration_light/178)\u000a", "date" : "2026-01-26 14:06:02 +0000", "id" : "667fe50e4910ab69eb300ec6972077f13cba2172", "msg" : "refactor(pipelines/pingcap/ticdc): optimize ticdc pipelines for resource", "paths" : [ { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_pulsar_integration_light_next_gen/pipeline.groovy" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_pulsar_integration_light/pipeline.groovy" }, { "editType" : "edit", "file" : "libraries/tipipeline/vars/prow.groovy" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_storage_integration_heavy_next_gen/pipeline.groovy" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_kafka_integration_heavy/pipeline.groovy" }, { "editType" : "edit", "file" : "libraries/tipipeline/vars/cdc.groovy" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_mysql_integration_light/pipeline.groovy" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_mysql_integration_light_next_gen/pipeline.groovy" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_kafka_integration_heavy_next_gen/pipeline.groovy" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_storage_integration_light_next_gen/pipeline.groovy" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_kafka_integration_light_next_gen/pipeline.groovy" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_mysql_integration_heavy_next_gen/pipeline.groovy" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_kafka_integration_light/pipeline.groovy" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_storage_integration_light/pipeline.groovy" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_mysql_integration_heavy/pipeline.groovy" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_storage_integration_heavy/pipeline.groovy" } ] } ], "kind" : "git" }, "culprits" : [ { "absoluteUrl" : "https://do.pingcap.net/jenkins/user/noreply", "fullName" : "noreply" } ] }
