[GitHub] [shardingsphere] sandynz opened a new pull request, #24883: Refactor PipelineContext to support JDBC mode in pipeline jobs

["sandynz (via GitHub)" <gi...@apache.org>]

sandynz opened a new pull request, #24883:
URL: https://github.com/apache/shardingsphere/pull/24883

   Currently, `PipelineContext` use static fields:
   ```
   public final class PipelineContext {
       
       private static volatile ModeConfiguration modeConfig;
       
       private static volatile ContextManager contextManager;
   ```
   
   When pipeline jobs are triggered in JDBC mode via ShardingSphereDataSource (every ShardingSphereDataSource has one context manager), modeConfig and contextManager might be overwritten, and then it might cause issue.
   
   Changes proposed in this pull request:
     - Remove static modifier in PipelineContext fields.
     - Add PipelineContextKey to identify context.
     - Add PipelineContextManager to get/put/remove context manager by PipelineContextKey.
     - Update ShardingSphereDataSource to trigger callbacks (ContextManagerLifecycleListener interface and impls) on context manager initialized and destroyed, it'll update pipeline contexts map in PipelineContextManager. And also ContextManagerLifecycleListener is updated.
     - Refactor PipelineJobId and impls, PipelineJobIdUtils.
     - Refactor APIFactory/API/service layers that depend on PipelineContext. e.g. PipelineAPIFactory, AbstractPipelineJobAPIImpl, PipelineDistributedBarrier, CDCJobAPI, MigrationJobAPI, PipelineDataSourceFactory, PipelineJobWorker, etc.
     - Update invocations in high level layer.
