ExArrow.FileSystem.Local (ex_arrow v0.9.0)

Local OS filesystem implementation of ExArrow.FileSystem.

Paths are expanded with Path.expand/1 before use. File contents are not read here; Dataset / Parquet NIFs open paths returned by discovery.

Example

fs = ExArrow.FileSystem.Local.new()
{:ok, entries} = ExArrow.FileSystem.list(fs, "/data/events")
{:ok, paths} = ExArrow.FileSystem.glob(fs, "/data/**/*.parquet")
ExArrow.FileSystem.exists?(fs, "/data/events")
