Call a redis command outside of transaction context

Question

Is it possible to call a predis command outside of transaction context? I mean to exec hget or hexist while a transaction is opened

Sounds like you need to use a Lua script instead of a tx - you can read and write data in the script — Itamar Haber, Jan 12 '16 at 12:15

No, it`s not possible. Transaction started with (MULTI) works in per connection pipeline. So you should DISCARD/EXEC first or use another predis connection to Redis server.

You can do it, but not on the same connection.

Here's a transaction that copies foo2 value to foo, foo2 is read by a second connection:

$responses = $client1->transaction()->set('foo', $client2->get('foo2'))->get('foo')->execute();

@misterion, I'm performing a redis call while a transaction is still open. I think that this is what the OP wanted. – Ofir Luzon Jan 13 '16 at 07:02
