Redis offers multiple ways to import data into a database; from an file, an script or from an existing Redis database.
Create a simple file
users.rediswith all the commands you want to run
HSET 'user:001' first_name 'John' last_name 'doe' dob '12-JUN-1970'
HSET 'user:002' first_name 'David' last_name 'Bloom' dob '03-MAR-1981'
redis-clitool to execute the script
redis-cli -h localhost -p 6379 < users.redis
This approach will only run the commands and will not impact the existing data, except if you modify existing keys in the script.
Sample dataset: You can find sample dataset ready to be imported using this method in the
Restore an RDB file
If you have an RDB file
dump.rdb that contains the data you want you can use this file to create a new database
dump.rdbfile into the Redis working directory
If you do not know what it is folder you can run the command
CONFIG get dirwhere your Redis instance is up and running
Start the Redis service with the
dump.rdbis automatically imported.
Connect to the database using
redis-clior any other client, to check that data have been imported. (for example
- Warning: Importing data erases all existing content in the database.
Import & Synchronize using RIOT
Redis Input/Output Tools (RIOT) is a set of import/export command line utilities for Redis:
- RIOT DB: migrate from an RDBMS to Redis, Search, JSON, ...
- RIOT File: bulk import/export data from/to files.
- RIOT Gen: generate sample Redis datasets for new feature development and proof of concept.
- RIOT Redis: live replication from any Redis database (including AWS Elasticache) to another Redis database.
- RIOT Stream: import/export messages from/to Kafka topics.
Import data into Redis Enterprise
You can easily import data into Redis Enterprise and Redis Enterprise Cloud, take a look to the following documentation:
