Transaction over multiple Databases

Hi,

i want to split my datas in multiple Databases.
To keep it safe i want to add or delete datas only in an transaction.

I found multiple code snippet like this:

using var con= await ConnectionMultiplexer.ConnectAsync("127.0.0.1:6379");
var tran= con.CreateTransaction();

var db1= con.GetDatabase(1);
var db2= con.GetDatabase(2);

... Add or Delete on db1 and db2

await tran.ExecuteAsync();

But there is no function CreateTransaction on the ConnectionMultiplexer object. This function is only available on the IDatabase but here i need to set the ID of the database. I think the transaction is only available on the single Database and not on all other.

Here is my Code. How can i add an transaction to keep it safe?

using var con = await ConnectionMultiplexer.ConnectAsync("127.0.0.1:6379");

var db1= con.GetDatabase(1);
var db2= con.GetDatabase(2);

... Add or Delete on db1 and db2

Start with ConnectionMultiplexer, GetDatabase, and CreateTransaction in the issue's example, then review the Redis transaction behavior relevant to database IDs. Determine whether operations on db1 and db2 can be covered by one transaction and document the supported outcome for the provided code.
