How to Dump a Redis Key in Windows Using CLI

redis dump key in windows

To dump a Redis key in Windows, you can use the Redis command-line interface (CLI) tool. Here’s how you can do it:

Prerequisites

1. Install Redis: Make sure you have Redis installed on your Windows machine. You can use the Windows Subsystem for Linux (WSL) or a native Windows port of Redis.
2. Access Redis CLI: You need to access the Redis command line interface.

Steps to Dump a Key

1. Open Command Prompt or PowerShell:

   • If you are using WSL, open your WSL terminal.
   • If you are using a native Windows port, open Command Prompt or PowerShell.

2. Connect to Redis:

   • If Redis is running locally, you can connect to it using the following command:

     redis-cli
     

   • If Redis is running on a different host or port, you can specify the host and port:

     redis-cli -h <hostname> -p <port>
     

3. Dump the Key:

   • Use the DUMP command to get the serialized value of the key. Replace <your_key> with the actual key you want to dump:

     DUMP <your_key>
     

   • This will return a serialized version of the key's value in a binary format.

4. Exit Redis CLI:

   • You can exit the Redis CLI by typing:

     exit
     

Example

Here’s an example of dumping a key named mykey:

redis-cli
> DUMP mykey

Note

• The DUMP command returns a serialized value that is not human-readable. If you want to restore this key later, you can use the RESTORE command.
• If you want to see the value in a more readable format, you can use the GET command (for string values) or other appropriate commands depending on the data type of the key.

Additional Commands

• To see all keys in the database:

  KEYS *
  

• To get the value of a string key:

  GET <your_key>
  

Conclusion

Using the DUMP command in Redis allows you to retrieve the serialized value of a key, which can be useful for backups or migrations. Make sure to handle the binary data appropriately if you plan to use
