Replaced repeated PostgreSQL queries with an in-memory friendship graph. ⚡

Lazy hydration + batching = 92% fewer DB queries.

Sometimes, a HashMap beats Redis. 🤷

@JiyaMittal86259 Exactly. Sometimes solving the right problem matters more than building the perfect solution. How do you usually figure out what users are actually struggling with?

@ijanvi_gupta01 Multiple dropped packets are handled the same way any sequence gap triggers a fresh snapshot, so we don’t try to replay every missed packet.

15KB per turn over WebSockets was choking multiplayer on 3G.

Switched to delta updates + sequence IDs:
15KB → 180B
320ms → 35ms

Dropped packets trigger a snapshot only when needed.

Good systems run on bad internet 🤷

@ijanvi_gupta01 This is so relatable. What do you check first when a desktop design starts breaking on mobile?

[Hunardeep Kaur @Hunardeep_21]

@prateekbuildshq So true. Setup issues somehow take longer to fix than the actual code.

@ayush17mahanta Right now we keep the pause subtle — just briefly disable input and show a small “Syncing…” state. The goal is to recover without making the connection issue feel disruptive to the player.

@stainedbyherrr We keep a small buffer for incoming deltas and check the sequence ID. If there’s a gap, we pause applying updates and request a snapshot rather than trying to guess the missing state.

@ayush17mahanta Interesting! Does it automatically switch back to Redis once it’s up?
