3.00.1

3.00.1.1

Improvements

Job parallelism can be set on the server side using setMaxJobParallelism.

3.00.1.0

New Features

For versions before 3.00.1.0, ResultSet may return a scalar/vector/matrix. Since version 3.00.1.0, these forms are converted and returned as tables

Note: This change may affect compatibility with existing code that expects scalar/vector/matrix return types.
The getResult method of JDBCResultSet has been marked as deprecated.
PreparedStatement aligns the handling logic of DECIMAL 32/64 data with DECIMAL128, which now supports string representation with setObject to ensure high-precision transmission.
The getColumns method of DatabaseMetaData now supports retrieval of column information for all tables under a specified catalog.schema.
