UnifiedJedis - can't use transaction and watch together

[veselov]

I've switched to using UnifiedJedis in my application, as I needed module commands.
I replaced using my own connection pool by having UnifiedJedis create and manage one.

One thing that I found lacking - is an ability to run a transaction with watches.

Watches have to be done on a connection, before multi is executed.
But UnifiedJedis only lets you get a transaction where multi has already been executed.

I didn't find any other way of making use of watch/multi, except for creating transactions on a connection that I somehow must obtain outside UnifiedJedis (and therefore can't use the latter as a single connection pool source).
