An extremely fast bartering farm can be made easily by building a farm to automatically stock it with hundreds of piglins. The drops are stored quickly using a manual mixed-item shulkerbox loader so that the drops can be sorted using a shulker box unloader and sorting system.
*If playing on 1.16 or 1.17, see Notes below for 9:58
*In 1.19+, piglins can pathfind out of the scaffolding, which causes some to die from entity cramming. The workaround is to replace the gate with a soul torch, and use a piston to drive in the top slab over the soul torch.

PAPER AND SPIGOT SERVERS have modified game mechanics that may impact the farm. Piglins with carved pumpkins may count towards the mobcap, so be sure to build the bartering farm more than 128 blocks from other mob spawning farms so that the other farms will continue to function. Some servers might be configured to make mobs cram despite being inside scaffolding. To fix this issue, set the configuration option fix-climbing-bypassing-cramming-rule: false. If you are unable to change the server settings, the farm will still work, but only with 46 piglins. Pathfinding may also be different, so piglins may have trouble falling into the trap. Adding more soul torches around the outer edge of the 4x4 pit seems to help.

NOTES
1:00 You only need 2 scaffolding. To reach the AFK spot, just pillar up on netherrack, which you can collect as you clear out the spawning room.
3:25 If you like, you can use Item Scroller mod to move your entire inventory at once.
5:21 The bartering farm can be placed near your gold farm for convenience, but it is best for the bartering farm to be far enough away so that the piglins are not loaded (causing lag) when you are not actually bartering.
8:19 A large number of piglins will create a bit of lag in the game. Using 128 carved pumpkins (for 128 piglins) is probably fine for most players and servers. I’m not sure there is much value in having more than 256. Also see comments above for Paper and Spigot servers.
9:58 The trap rate in 1.16 and 1.17 might be slower than in 1.18, so you may need to wait up to twice as long.
10:39 Rarely, you may find a baby piglin at the bartering farm, perhaps with a pumpkin on its head. Kill it before continuing.
11:04 If you have trouble nudging the piglins into the scaffolding, try powering the lever and depowering it again for another attempt. You can also use a piston to push the top slab into place.
11:54 If you’re playing on a Mac computer, pressing cmd-Q will quit the game. Use a different key binding for drop to avoid confusion.
12:15 Holding any item and shift-double clicking an occupied inventory slot will move all items of that type from your inventory to storage. This accelerates the storage process and often groups like items together. The shulker boxes are partially sorted as a result, as opposed to being completely unsorted.
