Redis Command: DUMP - BigBoxCode

Summary

Command Name	DUMP
Usage	Get serialized value of a key
Group	generic
ACL Category	@keyspace @read @slow
Time Complexity	O(1) + O(N * M)
Flag	READONLY
Arity	2

NOTES

O(1) is the complexity of accessing the key.
O(N * M) is the complexity of serializing the value
- N is the number of Redis objects that the value is composed of.
- M is the average size of the values.
In the case of an average-size string value, N=1, so the complexity will be O(1) + O(1 * M). If M is a small value, then the complexity will be O(1).

Signature

DUMP <key>

NOTES

This command will not fail in any case. It will always return some value, or will return null(nil) in case of a non-existing key.

Usage

Serialize the value of a key, in a specific format.

64-bit checksum is used, so that the RESTORE command can check the integrity of the data while restoring.

This command is very useful when we want to recreate or copy some value like a big list or set or hash etc, on the Redis server.

NOTES

We can use the serialize value to later recreate/restore the value. Redis command RESTORE can be used for the restoration.
The encoding format is the same as the format used for the RDB file. RDB version is also added to the encoded value.

If the key has an expiration time, then that expiration time is not stored in the encoded value.

Arguments

Parameter	Description	Name	Type
<key>	key name of the item	key	key

Return Value

Return value	Case for the return value	Type
encoded value	Encode value of the stored value	string
(nil)	If the key does not exist	null

In the encoded value we have RDB formatted value of the original stored value, then 2 bytes of RDB version, and then 8 bytes of CRC64.

NOTES

If we provide a non-existing key, then the command returns a null value(nil).

Command Examples

Here are a few examples of the DUMP command usage-

# Redis DUMP command examples
