What causes slow leaderboard pagination at deep offsets?

Pagination uses offset-based queries, so jumping deep into a large leaderboard is slow because it scans everything before the page.

How do I catch this when it only happens for some players?

Capture it automatically from the player's device with the full stack trace, the device and OS, the build, and a breadcrumb trail of what they did. That turns a vague complaint into a specific, reproducible issue you can fix without owning the hardware it happens on.

How to Handle Leaderboard Pagination Efficiently

Quick answer: Use rank-based or cursor pagination on a sorted structure, so any page of the leaderboard loads efficiently regardless of depth.

Offset pagination makes deep leaderboard pages slow. Rank-based pagination keeps them fast. Here is how.

How to fix it

1. Paginate by rank

Use the sorted structure's rank to fetch a page directly.

2. Use cursors

Page with cursors rather than large offsets.

3. Cache hot pages

Cache the top pages that are read most.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every backend error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.

Reproduce it once with full context and the fix writes itself. The hunt is the expensive part.
