The changes are based on performance analysis and aim to\u000amaintain test reliability while using fewer resources.\u000a\u000a### Why?\u000aRecent performance evaluations have shown that the existing resource\u000aallocations for these integration tests are higher than necessary. By\u000areducing the CPU and memory limits, we can:\u000a- Decrease infrastructure costs associated with running these pipelines\u000a- Improve resource availability for other concurrent jobs\u000a- Maintain the same level of test coverage and reliability\u000a- Align resource allocations with actual requirements observed during\u000atest execution\u000a\u000a### Changes Made:\u000a- **Build containers** (`pod-build.yaml` files):\u000a - Reduced CPU from 12 to 6 cores\u000a - Reduced memory from 16Gi to 8Gi\u000a\u000a- **Test containers** (`pod-test.yaml` and `pod.yaml` files):\u000a- For heavy integration tests: Reduced CPU from 12 to 6 cores and memory\u000afrom 32Gi to 16Gi\u000a- For light integration tests: Reduced memory from 16Gi to 8Gi (CPU\u000aalready at appropriate levels)\u000a\u000a### Affected Pipelines:\u000a1. **Kafka Integration Tests** (both heavy and light variants, current\u000aand next-gen):\u000a - `pull_cdc_kafka_integration_heavy`\u000a - `pull_cdc_kafka_integration_heavy_next_gen`\u000a - `pull_cdc_kafka_integration_light`\u000a - `pull_cdc_kafka_integration_light_next_gen`\u000a\u000a2. **MySQL Integration Tests** (both heavy and light variants, current\u000aand next-gen):\u000a - `pull_cdc_mysql_integration_heavy`\u000a - `pull_cdc_mysql_integration_heavy_next_gen`\u000a - `pull_cdc_mysql_integration_light`\u000a - `pull_cdc_mysql_integration_light_next_gen`\u000a\u000a3. **Pulsar Integration Tests** (light variants, current and next-gen):\u000a - `pull_cdc_pulsar_integration_light`\u000a - `pull_cdc_pulsar_integration_light_next_gen`\u000a\u000a4. **Storage Integration Tests** (both heavy and light variants, current\u000aand next-gen):\u000a - `pull_cdc_storage_integration_heavy`\u000a - `pull_cdc_storage_integration_heavy_next_gen`\u000a - `pull_cdc_storage_integration_light`\u000a - `pull_cdc_storage_integration_light_next_gen`\u000a\u000a### Impact:\u000aThese changes are expected to reduce resource consumption by\u000aapproximately 50% for CPU and 50-75% for memory across all affected\u000apipelines, while maintaining test reliability and coverage. The\u000aadjustments have been validated against recent test runs to ensure they\u000adon't compromise test stability or introduce flakiness.\u000a\u000aSigned-off-by: tenfyzhong \u000a", "date" : "2026-01-13 15:20:59 +0000", "id" : "25b5ab260fd9766cc4af8f2a537f588ae5d6c639", "msg" : "TiCDC: Reduce resource allocations in TiCDC test pipelines to optimize", "paths" : [ { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_pulsar_integration_light/pod-test.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_mysql_integration_heavy/pod-build.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_storage_integration_light/pod-build.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_mysql_integration_heavy_next_gen/pod.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_kafka_integration_heavy/pod-test.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_kafka_integration_light_next_gen/pod-test.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_mysql_integration_light/pod-test.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_storage_integration_light/pod-test.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_mysql_integration_light_next_gen/pod.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_kafka_integration_light_next_gen/pod-build.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_kafka_integration_heavy/pod-build.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_kafka_integration_heavy_next_gen/pod-test.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_storage_integration_heavy/pod-build.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_mysql_integration_heavy/pod-test.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_pulsar_integration_light/pod-build.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_kafka_integration_light/pod-test.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_storage_integration_heavy/pod-test.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_storage_integration_heavy_next_gen/pod.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_mysql_integration_light/pod-build.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_kafka_integration_heavy_next_gen/pod-build.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_kafka_integration_light/pod-build.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_storage_integration_light_next_gen/pod.yaml" }, { "editType" : "edit", "file" : "pipelines/pingcap/ticdc/latest/pull_cdc_pulsar_integration_light_next_gen/pod.yaml" } ] } ], "kind" : "git" }, "culprits" : [ { "absoluteUrl" : "https://do.pingcap.net/jenkins/user/noreply", "fullName" : "noreply" } ] }
