Ingest Java SDK release notes for 2025¶

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.

Upgraded the JDBC version to 3.24.2.

Beginning with release 4.0.0, the Ingest Java SDK now uses the Snowflake JDBC thin JAR instead of the fat JAR.

Updated dependencies and imports for Snowflake JDBC thin JAR.

Removed unnecessary dependencies.

Enhanced Channel Invalidation Handling. The channel object now automatically invalidates itself upon receiving a response from the server indicating an invalid channel state. This improvement enhances error handling and resource management within the SDK.

Fixed issues with the filename mismatch for Iceberg ingestion.

Made updates to silence the exception log in the JDBC driver.

Fixed issues with the Jenkins job to push artifacts to Maven.

Fixed the proxy settings for the OAuth HTTP client.

Fixed a Java formatter script and its dependencies.

Beginning with release 3.1.0, any duplicate keys in variant columns result in client-side errors with the INVALID_VALUE_ROW error code.

Upgraded the JDBC version to 3.22.0.

Upgraded the Netty version to 4.1.118.
