Is it possible to join vroomed tables without materializing?

No, though you can read multiple files at once into the same dataset if they have the same format (vroom.r-lib.org/articles/vroom.html#reading-multiple-files)

Any reasons not to use vroom With data.table?
@JimHester44 жыл бұрын
You certainly can, however currently data.table materalizes all ALTREP vectors when the data is converted to a data.table, which removes the benefits of the lazy parsing in vroom. If you subset your data prior to doing further data.table manipulations then it could still be worthwhile to use data.table however.
