Though some have run into issues (see ansible/awx#6365) — so for this operator it may be prudent to wait a little.

Hello,

Any predictions of when this operator will be updated for use with Redis?

[geerlingguy]

@fabiocruzcoelho - I will likely wait until closer to or after Ansible Tower 3.7 is released.
