Redis: Multi-Command Metrics and Replication Fixes
Today we're diving into two solid improvements to Redis core functionality. The star of the show is a HOTKEYS fix that now properly tracks each command inside MULTI/EXEC transactions, plus a clever Sentinel discovery fix for RDB channel connections. Both changes tackle edge cases that could trip up production deployments.

Hey there, Redis community! Welcome back to another episode. I'm genuinely excited about today's changes because we're looking at those satisfying fixes that make you go "oh yeah, that totally makes sense" once you see them.
So we've got two merged pull requests that are solving some really interesting edge cases in Redis. Let me paint you the picture of what's been happening.
First up, we have Slavomir Kaslev tackling something with HOTKEYS that honestly, I bet a lot of people didn't even realize was happening. You know how Redis has this awesome HOTKEYS feature that tracks CPU and network stats for different keys? Well, it turns out there was this quirky behavior where if you were using…
Think about it from a monitoring perspective. You've got this transaction that's doing five different operations on five different keys, but your hotkey tracking is just... missing all of that data. Not ideal when you're trying to understand your application's access patterns, right?
Slavomir's fix is elegant in its simplicity. Instead of skipping the per-command tracking during transactions, now each command inside that MULTI/EXEC block gets properly accounted for. The change touches the core…
