Mar 1, 2025March 2025 highlights for apache/inlong: reliability and metric accuracy improvements in streaming pipelines. Key outcomes include a bug fix to TubeMQ consumer session handling and a feature enhancement for precise CDC metrics in InLong Sort. These changes strengthen data reliability, observability, and governance alignment with Flink checkpointing. Key points: - Bug fix: Restored the checkpoint ID as part of the TubeMQ consumer session key to uniquely identify sessions and maintain state across restarts, improving reliability of TubeMQ message consumption in the Flink job. (Commit: 3db440b0c64eca4ac9ac1c929cad70a23b235ca3) - Feature: Introduced CdcExactlyMetric for precise MySQL CDC metrics in InLong Sort, replacing the generic metric to provide accurate CDC metrics and ensure better alignment with Flink checkpointing and audit reporting. (Commit: 4c9da1bb6ab7a5a31fdc77bdb406a83c61abf911)

Dec 1, 2024December 2024 monthly summary for apache/inlong focused on delivering data-format versatility and Transform SDK enhancements. The team implemented Kafka Sink KV Separator Support to improve handling of Key-Value data by extracting the entry splitter from KvConfig via KafkaIdConfig, enhancing data formatting and cross-serialization compatibility. In parallel, Transform SDK was extended to support RowData as both a source and sink, introducing decoding/encoding classes and a refactor to use self-defined conversion utilities for Field and RowData, enabling more flexible and reliable data transformations.
