SWAPDB

Usage:
SWAPDB index1 index2
Complexity:
O(N) where N is the count of clients watching or blocking on keys from both databases.
Since:
4.0.0
ACL Categories:
@keyspace, @dangerous, @write, @fast

This command swaps two Valkey databases, so that immediately all the clients connected to a given database will see the data of the other database, and the other way around.

Note: SWAPDB is disabled in cluster mode to prevent shard inconsistencies, as swapping databases on one shard while leaving others unchanged could lead to data inconsistencies.

Examples

SWAPDB 0 1

This will swap database 0 with database 1. All the clients connected with database 0 will immediately see the new data, exactly like all the clients connected with database 1 will see the data that was formerly of database 0.
