Redis MSET

Redis is a free and open-source in-memory database. It is a NoSQL database that stores data in a key-value pair. This means that a value is mapped to a specific unique key.

Learning how to work with key-value pairs is very important. This tutorial will discuss inserting single or multiple key-value pairs using the SET or MSET commands.

Redis Set Command

The Redis SET command adds a provide key value to a database. The syntax is as shown below:

An example is as shown:

If a specified key already exists, it is replaced with a new value. Consider the example below:

In this case, the value of key1 gets replaced with value2.

You can also set a key with an expiration value using the EX parameter. Sample sytax is shown:

Take a look at the example below:

After the expiration duration is elapsed, Redis will delete the key from the database. If you attempt to get the value, Redis will return nil.

To get how a long has before being dropped, use the TTL command as:

Redis MSET Command

The MSET command is very similar to the Redis command, except it inserts multiple key-value pairs.

The syntax is shown below:

Consider the example inserts below:

The example above inserts five key-value pairs in one command.

To get multiple values, you can use the MGET command as shown:

This should return the corresponding value for the existing key.

Conclusion

This article taught us to insert key-value pairs using the SET and MSET commands.

We hope you enjoyed the tutorial.
