2025 年 Ingest Java SDK 版本说明¶

Fixed vulnerable dependencies.

Improved the reliability of streaming ingest into Iceberg tables, ensuring that your data is consistently uploaded to the correct location.

Improved how the SDK manages table keys, which ensures that our system stays in sync and helps maintain the stability and security of your tables.

Improved system stability for high-volume data by allowing connections to retry for up to five minutes, preventing immediate closures.

Beginning with release 4.1.0, the Ingest Java SDK includes a behavior change to JSON handling to improve data integrity and performance. See the following list for details:

• Added robust validation to detect and prevent duplicate JSON object fields, including those with trailing null terminators.

• All JSON keys and values are now strictly enforced to be valid UTF-8, which improves data integrity and compatibility.

• Optimized the JSON serialization process to directly convert objects into JSON strings, bypassing an intermediate conversion step. This results in improved performance and reduced memory usage.
