EMQX Enterprise version 4.4.17 enhances the performance of the rule engine, and it also involves log enhancements and bug fixes.
This article provides a comprehensive guide on how to leverage the EMQX rule engine to persist data to HStreamDB, thereby enabling the storage and real-time processing of MQTT data streams.
This article describes how to use the EMQX Kuiper rules engine and how to implement controlling IoT devices according to the analysis result.
In EdgeX Geneva, EMQX Kuiper - an SQL based rule engine is integrated with EdgeX. The tutorial introduces how to use Kuiper to process the data from EdgeX.
In this scenario, it is required to bridge messages under the EMQX specified topic that meet the criteria to the Pulsar . To facilitate subsequent analysis and retrieval, the message content needs to be split.
Redis is a fully open source, high-performance key-value database that adheres to the BSD protocol for free.

OpenTSDB is an extensible distributed time series Database database, whose bottom layer relies on HBase and makes full use of HBase's features of distributed column storage to support millions of reads and writes per second.
TDengine is an open source big data platform designed and optimized for Internet of Things, Internet of Vehicles, Industrial Internet, IT operation and maintenance, etc., launched by TAOS Data (Beijing TAOS Data Technology Co., Ltd.). In addition to the core timing database functions that are more than 10 times faster, it also provides functions such as caching, data subscription, and streaming computing to minimize the complexity of R & D, operation and maintenance.
InfluxDB is an open source database for storing and analyzing time series data, with built-in HTTP API, and the support for SQL-like statements and unstructured features are very friendly for users. Its powerful data throughput and stable performance make it ideal for the IoT area.
In this scenario, it is required to store the messages that meet the criteria under EMQX in the MySQL database. In order to facilitate subsequent analysis and retrieval, the message content needs to be split for storage.
