## Summary of Changes Hello @ATHARVA262005, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request significantly enhances the scalability of `SparkReceiverIO` by introducing a mechanism for parallel data reading. It moves away from a single-worker limitation by allowing users to configure the number of concurrent readers, effectively distributing the data ingestion workload across multiple Beam workers. This change improves throughput and resource utilization for Spark-based data sources within Beam pipelines, while maintaining compatibility with existing configurations. ### Highlights * **Parallel Reading Implementation**: Introduces parallel reading capability to SparkReceiverIO to address a single-worker bottleneck, significantly improving scalability. * **New Configuration Option**: Adds a new `withNumReaders(int)` configuration option to the `SparkReceiverIO` builder, allowing users to specify the number of concurrent readers. * **Parallel Work Distribution**: Implements a `Create.of(shards)` and `Reshuffle` pattern in the `expand()` method to distribute reading tasks across multiple Beam workers when `numReaders` is greater than 1. * **DoFn Refactoring**: Refactors `ReadFromSparkReceiverWithOffsetDoFn` to accept `Integer` shard identifiers instead of `byte[]`, enhancing type safety and integration with the new parallelization logic. * **Backward Compatibility**: Ensures strict backward compatibility, reverting to single-worker behavior if `numReaders` is not set or explicitly set to 1. 🧠**New Feature in Public Preview:** You can now enable **Memory** to help **Gemini Code Assist** learn from your team's feedback.
