3.00.5.0

New Features

• Added an asynchronous write utility for the multi-active deployment architecture of DolphinDB.
• Added interface UpdateListener for StreamingSQLClient to enable real-time monitoring of Streaming SQL subscription data changes and allow users to process the updates as needed.
• Added method getStreamingSQLSubscriptionInfo for StreamingSQLClient to retrieve subscription information based on queryId.
• Added method Appendfor BasicAnyVector to append data in forms such as matrix, set, table, and dict.
• Added method appendEventWithResponse to synchronously wait for the response of a specific event.

Improvement

• Optimized the EOFException error message when canceling subscriptions.

Issues Fixed

• Fixed an issue where StreamingSQLClient reported an error when updating tables while writing any data.
• Fixed a vulnerability in the lz4-java dependency used by the Java API, replacing org.lz4 with at.yawk.lz4.

3.00.4.2

Issues Fixed

• Fixed a race condition in the ThreadPooledClient.unsubscribeInternal method to prevent MessageParser from triggering an unnecessary reconnection after receiving an EOF signal during unsubscription.

3.00.4.1

New Features

• Added a filter parameter to EventClient.subscribe to allow subscribing only to specific events based on filtering conditions.

Issues Fixes

• Fixed an issue where serialization failed for BasicDictionary objects whose values were not scalars.

• Fixed an issue where TopicPoller.poll returned an empty list when the timeout parameter was set to 0.

3.00.4.0

New Features

• Added Util.createVector(type, size, capacity) for creating vectors.
• Added new vector creation methods, such as BasicIntVector(int size, int capacity), to specify the initial size and capacity.
• Added support for setting and adding values in vectors using Java primitive types.
• Added support for creating Decimal vectors directly from a list of strings (List<String>).
• Added support in MTW for inserting data into stream tables in Orca.
• Added support for StreamingSQLClient, enabling declaration of streaming SQL tables, registration of streaming SQL queries, and subscription to streaming SQL query results.
• Added support in BasicAnyVector for the Append method to add single values or entire vectors, and for the set method to modify elements at any position.
• Added method getScale to BasicArrayVector interface for obtaining the scale of a DECIMAL array vector.

Fixed Issues

• Fixed an issue where constructing BasicDecimal32Vector with Integer.MIN_VALUE as null value caused errors.

3.00.3.2

Issues Fixed

• Fixed an issue with vector serialization and deserialization during CEP event sending and subscription.

3.00.3.1

Issues Fixed

• Fixed an issue where the Java process could crash during node failover when enableHighAvailability=true.
• Fixed an issue where the process would hang when the script contained null characters.
