Hold That Chunk
by dlee13
Hold That Chunk keeps chunks the client has already received from being dropped the moment the server unloads them, so ice boat and elytra racers do not fly into blank terrain on busy servers.
What it does
When the server sends a chunk unload packet, the Fabric client does not discard the chunk at once. Instead, cached chunks are removed periodically, with the ones farthest from the player cleared first. This gives the client time to redraw terrain that would otherwise appear empty while fresh chunk data is still arriving over the network.
The effect matters most on multiplayer servers where many players moving at high speed can outpace the server's ability to send chunk updates. Without the mod, a player in that situation starts moving into empty chunks. Fabric API is required, and the mod is client-side only, so servers do not need it and players install it alone.
The mod is released under the MIT License, and its source code and issue tracker are public. Cloth Config API, Mod Menu and YetAnotherConfigLib (YACL) are optional and only add configuration screens. Builds cover 1.18 – 1.21.1, with the latest file, 2.1.0, targeting 1.21.1.
Key features
Delayed chunk unloading
Chunk unload packets from the server are held back, and cached chunks are removed on a timer instead of immediately.
Distance-based cleanup
Cached chunks are cleared according to their distance from the player, with those farthest away removed first.
Faster terrain redraw
Cached chunks can be drawn again before fresh data arrives, which reduces empty terrain during fast travel.
Ignore server render distance
An option in the mod's config lets the client set a higher view distance than the server allows.

Use cases
Ice boat racing
Racers moving at high velocity on a busy server keep terrain drawn while the server catches up with chunk updates.
Elytra course racing
Elytra courses cross large areas quickly, so cached chunks help keep the route visible on loaded servers.
Who it’s for: Players who race on crowded multiplayer servers, and players who want a larger view distance than the server sets.
How it compares
Easy Chunk Loader is a Fabric mod for 1.19.3 that runs on the client and server together, and it is open source under the MIT License. Slime is a server-side only Fabric mod for 1.18.1 – 26.2, open source under the GNU Lesser General Public License v3.0 only. Racing Minimap is a client-side only Fabric mod for 1.21.1 – 1.21.11 that is open source under the GNU General Public License v3.0 only, so it addresses navigation rather than chunk caching.

What the author says
This Fabric loader mod prevents the Minecraft client from immediately unloading chunks when it receives chunk unload packets from the server. Instead, client chunks get periodically cleaned up based on distance away from the player. This chunk unloading strategy is particularly useful for participating in ice boat…
