3.0.3.0

New Features:

• You can now create windowed queries that are triggered by events - just specify any conditions that TDengine supports, including operations on different columns.
• Indexing on any tag: You can now create an index on any tag, enabling improved query performance when filtering by tag.
• (Enterprise Edition only) Data compaction: TDengine Enterprise Edition now provides the COMPACT statement to reorganize your database and remove gaps from deleted or updated records. This can greatly improve storage and query performance on deployments that have been running for some time.
• (Enterprise Edition only) TDengine Explorer: TDengine Enterprise Edition now offers a convenient GUI to make ad hoc time-series operations and instance management even easier.
• (Enterprise Edition only) Local backup and migration: The latest version of taosX included with TDengine Enterprise Edition 3.0.3.0 can back up and restore a TDengine deployment from a local file. taosX can also migrate data from existing TDengine 2.6 or 3.x deployments to TDengine 3.0.3.0, either incrementally or in full.

Enhancements:

• Results of stream processing can be stored in existing stables
• You can specify tags when storing the results of stream processing
• Data can be subscribed over websocket using Java Connector
• Data can be subscribed over websocket using Python Connector
• You can monitor HTTP status code on Grafana Dashboard
• Grafana plugin supports multi-dimensional alerts
• taosBenchmark can write data into sepcified range of child tables
• taosBenchmark can specify the number of vgroups on command line
