What it is

  • Cache
  • Queues
  • In-memory
  • Telegram bots

Redis is an in-memory data store. It is used as a cache, task queue, store for sessions and Telegram bot states, counters and rate limiting.

Sub-millisecond responses take load off your main database: frequent queries are served from Redis instead of PostgreSQL or MySQL.

The command runs the official Redis 8 image with persistence to disk. The port is reachable only from the server itself. Redis 8 is distributed under a choice of three licenses, one of which is AGPL-3.0.

  • Strings, hashes, lists, sets and streams
  • Pub/Sub and task queues
  • Key TTLs: cache and sessions
  • Persistence to disk (RDB and AOF)
  • Search and JSON built into Redis 8

Recommended plan

For Redis: at least 1 vCPU, 2 GB RAM and 10 GB NVMe.

How to install

Three steps in the bot or one command over SSH; installation takes about 45 seconds.

  1. 01

    Choose a plan in the bot

    Open @ExpressHost_bot and pay for a VPS. The server will be ready in about 60 seconds.

  2. 02

    Add Redis

    At the “Add-ons” step pick the script from the library, or run it later: Server settings → Scripts.

  3. 03

    Check that it works

    docker exec -it redis redis-cli ping (response: PONG)

Manually over SSH

Redis FAQ

Didn’t find an answer? Message @ExpressHost_SupportBot.

How much memory is needed?

Redis keeps all data in RAM. A few hundred megabytes is enough for a small project's cache; the limit is set with the --maxmemory parameter.

Will data be lost on reboot?

With --save 60 1, Redis saves a snapshot to disk every minute if there were changes. For more durability, enable --appendonly yes.

Where is the data stored?

In the redis-data Docker volume (the /data folder inside the container).

Redis installs at checkout — in the bot.
