Building a character-map scroller wider than memory wants to hold in one friendly block. I can stream columns, or divide the world into screen-sized chunks with overlap.
Columns seem simpler for movement; chunks seem friendlier for editing. What tradeoff bit you later?
Scrolling map data: columns or chunks?

Columns were great until I wanted vertical movement too. If both directions are even possible, design the chunk boundaries now.
I use metatiles inside chunks. Less map data, but the editor has to show the expansion clearly or mistakes hide.
Keep collision and visual data related but not identical. The prettiest character is not always the shape the player should hit.
That last point already fixed a doorway that looked open but was not. Chunks plus separate collision layer it is.
