What is Apache IoTDB?

Apache IoTDB is closing the SQL expressiveness gap while keeping its IoT-native core.

IoTDB 2.x has reached a level of SQL completeness — set operations, CTEs, window functions, JOIN variants, MATCH RECOGNIZE, and now logical views — that makes it viable for data engineers who previously had to export time-series data into a relational database for complex analysis. The 1.3.x branch is in maintenance mode, receiving only security backports. The AINode capability adds built-in ML models (Timer-XL, Timer-Sundial) for in-database forecasting.

What is NATS?

NATS second release candidates add a config reload check and faster redelivery queues.

NATS keeps the 2.14 and 2.15 lines in step, and on November 6 both got a second release candidate. The RCs make filtered filestore scans skip non-matching messages, stop redelivery queues from copying whole backlogs on each dequeue, and fix AckAll and gateway interest bugs. 2.15.3-RC.2 also adds a -t --test_reload flag that tells operators whether a config change needs a restart.

Apache IoTDB vs NATS: editorial side-by-side

A2.5

Apache IoTDB is closing the SQL expressiveness gap while keeping its IoT-native core.

◆ Current state

IoTDB 2.x has reached a level of SQL completeness — set operations, CTEs, window functions, JOIN variants, MATCH RECOGNIZE, and now logical views — that makes it viable for data engineers who previously had to export time-series data into a relational database for complex analysis. The 1.3.x branch is in maintenance mode, receiving only security backports. The AINode capability adds built-in ML models (Timer-XL, Timer-Sundial) for in-database forecasting.

◆ Where it's heading

The 2.x line is systematically adding relational SQL expressiveness atop the IoT-native storage core, adding 2-4 SQL features per release. The C-language SDK signals an intent to expand beyond JVM-centric deployments into embedded and industrial control contexts. AINode points toward a longer arc: time-series forecasting and anomaly detection executed directly in the database, reducing the need to export data to Python for ML workflows.

◆ Prediction

The next releases will likely complete table model SQL parity with standard features still missing, and expand AINode inference to cover more model types or expose forecasting via standard SQL function syntax.

DEVOPS
5.0

NATS second release candidates add a config reload check and faster redelivery queues.

◆ Current state

NATS keeps the 2.14 and 2.15 lines in step, and on November 6 both got a second release candidate. The RCs make filtered filestore scans skip non-matching messages, stop redelivery queues from copying whole backlogs on each dequeue, and fix AckAll and gateway interest bugs. 2.15.3-RC.2 also adds a -t --test_reload flag that tells operators whether a config change needs a restart.

◆ Where it's heading

The project is in a hardening stretch on both lines, with JetStream efficiency and correctness fixes landing alongside small operator tools. Account-hash subject mappings from RC1 remain the main new routing feature heading to release.

◆ Prediction

Expect 2.15.3 and 2.14.10 final releases shortly, carrying the RC2 fixes and the reload check.
