TencentDB for MongoDB

Fitted with an ultra-large memory, brand-new PCI-E SSD storage media, next-gen storage engine and optimized native Mongo kernel, TencentDB for MongoDB can process 30,000+ queries per second (QPS), helping sustain massive volumes of concurrent requests during peak business hours. Furthermore, it eliminates the need to design complex backend systems for processing high numbers of requests, greatly simplifying your system development process.

Compatible with most native protocols, Tencent's proprietary distributed MongoDB cluster stores data on multiple physical servers through shard keys, enabling unlimited storage capacity and load distribution. One-click cluster creation and capacity expansion significantly improves the efficiency of building massive distributed storage systems. 

DynamoDB is a highly scalable NoSQL database service that supports document and key-value storage models. Based on the existing NoSQL module framework, the TencentDB team has developed a highly DynamoDB-compatible database service that features speed and stable performance, supports instance-level backup and rollback and boasts an automatic disaster recovery mechanism.

With a complete automatic data backup and lossless recovery mechanism, each instance cluster is backed up once a day by default, while dual-server hot backup is performed in real time for the nodes in the cluster. This completely eliminates the concerns over data loss and saves the extra investment required for ensuring high data reliability. Data encryption service is available for another layer of security protection.

Monitoring is available in three dimensional metrics including single instance, primary node and secondary node as well as professional data metrics such as disk usage, CPU load and QPS. The operational data are visualized for clear display.

Instance deployment, version updates and troubleshooting are well taken care of by the TencentDB team. The master/slave switchover, troubleshooting and data migration are completely imperceptible, and the IP and port remain unchanged. Without the need to worry about IP drift for your applications, OPS costs are greatly reduced.

When the available storage capacity is insufficient, the capacity can be expanded online via the console. The expansion process does not affect your online businesses and can be done conveniently and quickly with one click in the console, eliminating the need to care about the underlying implementation details.

Dual-server hot backup and multiple fault detection mechanisms ensure that the service is automatically switched to the slave server in a matter of seconds in case of failure with the master server. No operations are required on your end and there is no impact on your online businesses. High service availability is ensured with no additional development of related systems required.

The custom alarming feature is available for resource thresholds to help detect operational issues of MongoDB. It promptly notifies OPS personnel of the issues, enabling them to respond quickly to database problems.
