3.00.1

3.00.1.1

Improvements

The default value of parameter parallelism for the following methods has been modified from 2 to 64:
- run and tryRun methods of DBConnection and ExclusiveDBConnectionPool classes.
- Constructor of BasicDBTask.

3.00.1.0

New Features

Added support for Complex Event Processing (CEP) Engine with the following classes:
- EventSchema for defining events;
- EventSender for writing events into a heterogeneous stream table;
- EventClient for subscribing events from a heterogeneous stream table.
Added support for Decimal matrices.

Issues Fixed

Changed the default value of the BasicStringMatrix class from Symbol to String.
Fixed incorrect message offsets for streaming subscription.
Fixed an issue where using the set(int index, IScalar value) method to set Decimal vector values did not round correctly when the scalar's scale was greater than the vector's scale, leading to inaccurate results.
