How to Import Data into Redis

For developersImport Data into Redis

Redis offers multiple ways to import data into a database; from an file, an script or from an existing Redis database.

#Import using reds-cli script

1. Create a simple file users.redis with all the commands you want to run

2. Use the redis-cli tool to execute the script

This approach will only run the commands and will not impact the existing data, except if you modify existing keys in the script.

INFO

Sample dataset: You can find sample dataset ready to be imported using this method in the https://github.com/redis-developer/redis-datasets repository.

#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

Copy the dump.rdb file into the Redis working directory

If you do not know what it is folder you can run the command CONFIG get dir where your Redis instance is up and running
Start the Redis service with the redis-server
The file dump.rdb is automatically imported.
Connect to the database using redis-cli or any other client, to check that data have been imported. (for example SCAN)
