Welcome to Distributed Cache Service API Reference. Distributed Cache Service (DCS) is an online, distributed, in-memory cache service compatible with Redis and Memcached. It is reliable, scalable, usable out of the box, and easy to manage, meeting your requirements for high read/write performance and fast data access.

This document describes how to use application programming interfaces (APIs) to perform operations on DCS, such as creating, deleting, and scaling up DCS instances. For details about all supported operations, see API Overview.

If you plan to access DCS instances through an API, ensure that you are familiar with DCS concepts. For details, see DCS Service Overview.

  • Some APIs are supported only in certain regions.
  • DCS is continuously upgraded with new functions, and the existing APIs are inevitably adjusted. For example, new response parameters may be added.
  • To reduce the impact of API changes, DCS is backward compatible with APIs when possible. However, when you use DCS, you should accept and ignore unused parameters and parameter values in returned content (in JSON format).
  • For details on how to access DCS Redis or Memcached instances through clients in various languages, see the Distributed Cache Service User Guide.
