Release 3.0.5

Added

• Added support for high-performance batched writes with parameter interpolation:
  • supportManyParameters=1: Enables parameter interpolation to bypass 256-parameter limit (default: 0)
  • EnableBatchedInserts=1: Enables multi-row INSERT batching (default: 0)
  • BatchInsertSize=<SIZE>: Maximum rows per batch (default: 1000)
  • Note: Large batches are chunked for execution. If a chunk fails, previous chunks remain committed (no transaction rollback). Consider using staging tables for critical workflows.
• Added Feature-flag integration for SQL Exec API rollout
• Call statements will return result sets in response
• Add a gating flag for enabling GeoSpatial support: EnableGeoSpatialSupport. By default, it will be disabled

Updated

• Minimized OAuth requests by reducing calls in feature flags and telemetry.
• Geospatial getWKB() now returns OGC-compliant WKB values.

Fixed

• Fix: SQLInterpolator failing to escape temporal fields and special characters.
• Fixed: Errors in table creation when using BIGINT, SMALLINT, TINYINT, or VOID types.
• Fixed: PreparedStatement.getMetaData() now correctly reports TINYINT columns as Types.TINYINT (java.lang.Byte) instead of Types.SMALLINT (java.lang.Integer).
• Fixed: TINYINT to String conversion to return numeric representation (e.g., "65") instead of character representation (e.g., "A").
• Fixed: Complex types (Structs, arrays, maps) now show detailed type information in metadata calls in Thrift mode
• Fixed: incorrect chunk download/processing status codes.
• Shade SLF4J to avoid conflicts with user applications.

v3.0.4

Added

• Added support for telemetry log levels, which can be controlled via the connection parameter TelemetryLogLevel. This allows users to configure the verbosity of telemetry logging from OFF to TRACE.
• Added full support for JDBC transaction control methods in Databricks. Transaction support in Databricks is currently available as a Private Preview. The IgnoreTransactions connection parameter can be set to 1 to disable or no-op transaction control methods.
• Added a new config attribute DisableOauthRefreshToken to control whether refresh tokens are requested in OAuth exchanges. By default, the driver does not include the offline_access scope. If offline_access is explicitly provided by the user, it is preserved and not removed.

Updated

• Updated sdk version from 0.65.0 to 0.69.0

Fixed

• Fixed SQL syntax error when LIKE queries contain empty ESCAPE clauses.
• Fix: driver failing to authenticate on token update in U2M flow.
• Fix: driver failing to parse complex data types with nullable attributes.
• Fixed: Resolved SDK token-caching regression causing token refresh on every call. SDK is now configured once to avoid excessive token endpoint hits and rate limiting.
• Fixed: TimestampConverter.toString() returning ISO8601 format with timezone conversion instead of SQL standard format.
• Fixed: Driver not loading complete JSON result in the case of SEA Inline without Arrow

Releasing 3.0.3 to Maven

Updated

Fixed

v1.0.8-oss

Added

• Added DCO (Developer Certificate of Origin) check workflow for pull requests to ensure all commits are properly signed-off

• Provide an option to push telemetry logs (using the flag ForceEnableTelemetry=1). For more details see documentation
• Added putFiles methods in DBFSVolumeClient for async multi-file upload.
• Added validation on UID param to ensure it is either not set or set to 'token'.
• Added CloudFetch download speed logging at INFO level

Fixed

• Added explicit null check for Arrow value vector when the value is not set and Arrow null checking is disabled.
