Redis Connection Multiplexing
Muhammad Anees
In the Mixx Tanzania wallet app, every Redis call opened its own connection. At peak, that went past the connection limit and caused downtime.
What I did
Found the per-call connection pattern behind the outages
Replaced it with one shared, multiplexed Redis connection across the app
Result
600k+ concurrent sessions without running out of connections

Mixx Tanzania opened a Redis connection per call and hit the limit at peak. One shared, multiplexed connection now holds 600k+ concurrent sessions.
