Client.Pipelined().TxPipeline() is not a transaction?

[ash2k]

Hi! Just getting familiar with the library and I'm looking to do the following:

var c *redis.Client = ...
_, err := c.Pipelined(ctx, func(p redis.Pipeliner) error {
    // Do stuff with p
    // ....

    // Inner transactions
    for ... {
        _, er r:= p.TxPipelined(ctx, func(pTx redis.Pipeliner) error {
            // Do stuff with pTx
        }
    }
    // Do more stuff with p
    // ....

    return err
}

The code above does not seem to wrap the nested pipeline into a transaction, is that right? Is that a bug?

Hm, I guess what I want is to have a pipeline of many transactions. Can I do that?

@ash2k no, having multiple transactions in a pipeline is not supported.

To achieve that you can use Lua script: https://redis.io/commands/eval to execute multiple operations in single transaction. Since it's treated as single command then you can surround that with pipeline to send multiple commands at once.
