Introduction to the Cluster Mode
The CloudTable cluster mode provides a distributed, scalable, and fully managed NoSQL data storage system based on Apache HBase. It provides strong consistency and single-digit millisecond latency so it is optimal for storage and queries of massive amounts of structured and semi-structured data. In addition, the CloudTable cluster mode integrates the following functions:
- OpenTSDB 2.3.0: It is an open source OpenTSDB time series database.
- GeoMesa: It is a distributed, scalable, open source spatiotemporal database based on HBase.
In CloudTable cluster mode, you need to create a dedicated cluster and can use it on demand. Dedicated clusters are physically isolated and are not affected by other services, facilitating user management. The CloudTable cluster mode is applicable to users with high service throughput and low delay requirements.
After a CloudTable cluster is created, you can access the CloudTable cluster using the following methods.
- Using a client to access the cluster
For details, see the following sections:
- Using HBase: This section describes how to use the HBase shell to access a cluster.
- Using OpenTSDB: This section describes how to use the cURL or Postman or compile code to send HTTP requests for calling APIs to access OpenTSDB.
- Using GeoMesa: This section describes how to use the GeoMesa command line tool to access the GeoMesa spatiotemporal database.
- Call native open source APIs to develop HBase, OpenTSDB, and GeoMesa applications, and access the cluster through a CloudTable link.
For details, see CloudTable Service Developer Guide.
The CloudTable cluster mode has been put into commercial use. For details about CloudTable pricing, see Pricing Details.
