Efficient reading and writing of time series data

Time Series Database (TSDB) supports efficient reading and writing of time series data. The response time for reading one million data points is less than 5 seconds. A maximum of 10 million data points can be written per second.

  • Data writing

TSDB allows you to write data through HTTP or TSDB Java Client.

  • Data query

    TSDB allows you to query data through HTTP, TSDB Java Client, or the TSDB console. The console-based data query feature supports visualization of data grouping, downsampling, and space aggregation.

Data management

  • Data TTL setting

You can set the TTL for data through the console or the API. After the data TTL is set, the system marks the data as invalid when it expires, and automatically cleans it up at the specified time.

  • Data cleanup

You can clean up data based on metrics in the console or use the API to clean up data more flexibly.

Highly compressed storage

TSDB uses the efficient data compression technology, which reduces the average storage space required for a data point to one to two bytes. This not only reduces overall storage usage by 90%, but also increases the data writing speed.

Computing capability of time series data

TSDB provides professional and comprehensive computing functions for time series data, and supports downsampling, data interpolation, and space aggregation. This can meet the requirements of various complicated data query scenarios.

Monitoring and O&M

TSDB provides an instance O&M system. This system allows you to monitor the instance running status, performance metrics, and storage space usage in real time. You can also configure the alerting mechanism to detect resource bottlenecks at the earliest opportunity.

Data and instance security

TSDB provides the following solutions to protect your data and instances:

  • Provides the VPC-based instance access mode to fully secure the access to your instance.
  • Provides the IP address whitelist. Only the servers on the whitelist are allowed to access your instance, which further secures the access to your instance and data. If a server is deployed in a VPC network but not included in the whitelist, the server cannot access your instance.
  • In TSDB, data is stored in three copies to fully ensure data availability.

Integration with Realtime Compute

TSDB has been integrated with Alibaba Cloud Realtime Compute. For more information, see Create a TSDB result table.
