As with all other dimensions in the game, the CandyLands can generate infinitely. However, there are some limitations, as detailed below.
The CandyLands encompasses the height limit (y=256), down to the Void (y=0), and extends for millions of blocks in every direction on the horizontal plane. Technically speaking, the CandyLands is generated through a process which creates multiple noise maps to create differing elevations, general chunk shapes, and complex mountain and cave systems.

Chunks are the method used by the world generator to divide maps into manageable pieces. Chunks measure 16 blocks wide, 16 blocks long, and 256 blocks high, for a total volume of 65,536 blocks. Chunks are generated around players when they first enter the world, and as they wander around the world, new chunks are generated as needed. By adjusting the render distance, the player can adjust the number of chunks that will be loaded into memory, ranging from 25 chunks up to 1089.
Only chunks within the set range may have activity (mobs spawning, trees growing, water flowing, dropped items disappearing etc.), while chunks outside of this range are inactive, and are stored on the disk; this type of management is required so that players' computers do not need to track hundreds or thousands of blocks and entities at once. Note that this does not apply to spawn chunks, which will always experience activity regardless of how far away the player travels.
Visual cutoff point of a Minecraft map (Left is normal Minecraft generation, the right is after limitation.)
While the CandyLands are essentially infinite, the number of blocks the player may physically walk on is limited. The map contains a world border at +/- 29,999,984 X/Z. The world border is an animated wall of blue stripes; as you approach, the edges of the screen will tint red for several seconds. Most entities are unable to pass the border, except through teleporting. Players who breach the border will receive constant damage, unless they are in Creative mode.
