Tablestore is a storage service that is developed by Alibaba Cloud. Tablestore can store a large volume of structured data by using multiple models, and supports fast data query and analytics. Empowered by the distributed storage and index-based search engine, Tablestore can store petabytes (PBs) of data while delivering tens of millions transactions per second (TPS) at ultra-low latency (milliseconds).

Features

  • Fully managed

    Tablestore is a fully managed storage service for structured data, and supports software and hardware provisioning and configurations, error handling, cluster scaling, and security mechanisms. Tablestore ensures the availability of your business and helps you reduce management and O&M costs. This way, you can focus on developing your business.

  • Seamless scaling

    Tablestore uses shards and load balancing to perform seamless scaling operations. When the data volume increases, Tablestore automatically scales the sizes of data partitions. This allows you to store a large volume of data. Tablestore can store a minimum of 10 PB of data. A single table can store a minimum of 1 PB of data or 1 trillion data records.

  • Powerful query capabilities
    Tablestore supports queries based on secondary indexes and search indexes in addition to queries based on primary keys.
    • Secondary index: defines a custom data structure that can be used to improve query efficiency based on your business scenarios.
    • Search index: supports query methods such as boolean query, fuzzy query, geo query, and full-text search based on inverted indexes and column store.
    • SQL query: compatible with MySQL query syntax and supports table creation by using DDL statements. For existing tables, you can execute the CREATE TABLE statement to create mapping tables. Then, you can use SQL statements to access data in the tables.
  • High reliability

    Tablestore creates multiple backups of data and stores the backups in different servers across physical racks. When a backup fails, the system immediately switches over to a different backup server to restore the data. This mechanism ensures service availability of 99.99999999% (ten 9s).

  • Strong consistency

    Tablestore ensures consistency across all three backups. After a write success response is returned, applications can read new data in real time.

  • Highly concurrent read and write operations

    Tablestore supports tens of millions of concurrent read and write requests.
