New Features and Improvements

  1. Full functional Join: including LEFT JOIN, RIGHT JOIN, FULL JOIN, SEMI JOIN, ANTI-SEMI JOIN in traditional databases, as well as ASOF JOIN and WINDOW JOIN in time series databases
  2. Composite Primary Key: time-series data is organized and sorted according to both timestamp and an additioanl column, which is called primary key
  3. Double replicas (Enterprise only): high availability and high reliability can be achieved with 2 replicas, i.e. lower hardware cost compared to 3 replicas
  4. S3 storage (Enterprise only): cold data can be stored in S3 to achieve lower storage cost, without compromising query or writing behavior
  5. TSMA: time-range SMA to accelerate aggregate query
  6. Configurable compression: encoding method, compression algorithm and compression level can be configured per column when creating super table
  7. Count Window: A new type of window based on counting rows can be used in both stream and batch processing
  8. Active-Active (Enterprise only): two standalone TDengine deployments can form a single business system to provide high availability with transparency to the client programs. It can also be used in disaster recovery
  9. Database Encryption (Enterprise only): database storage files are encrypted with transparency for reading and writing
  10. Multi-level storage (Enterprise only): Up to 64 mount points can be configured for each storage level
  11. Data In (Enterprise only): time-series data stored in postgreSql and MySQL can be replicated to TDengine in real time
  12. Data In (Enterprise only): optimized configuration method for OPC data points
  13. Data Explorer: a simplified version of data explorer is public for the community
