It looks like the tests are passing, so is #190 still an issue?

[jamesholcomb]

So far the changes have fixed #190 for me (I have not released a production build internally however). As I don't utilize node-redis but need sentinel support, I removed node-redis in favor of ioredis for the adapter impl.

[daffl]

That's great. Though I don't think the original Redis driver would still work with this change. I'm thinking it'd either should be its own adapter or feature detect the driver. I'm still not sure what exactly it does differently 🤔

[jamesholcomb]

The difference is that node-redis does not support Sentinels redis/node-redis#302 which is necessary for HA

feathers-sync worked implicitly with both through 2.4.0. The changes in 3.0.0 broke the redisClient compat with ioredis

I actually started the PR with the intent of supporting both, but got fed up working in js. The repo needs a TS conversion.
