Restore an archived Parquet file to the active schema directory

Moves an archived Parquet file back into the schema directory, stripping the timestamp suffix to recover the original filename. If a current file already exists at the destination, it is archived first (when archive = TRUE) or the function stops (when archive = FALSE).

Usage

pq_restore(
  file_basename,
  schema,
  data_dir = NULL,
  archive = TRUE,
  archive_dir = "archive"
)

Arguments

file_basename

Basename of the archived file (with or without the .parquet extension), e.g. "company_20251109T072042Z".

schema

Schema name.

data_dir

Root directory of the Parquet data repository. Defaults to the DATA_DIR environment variable, with interactive setup when needed.

archive

If TRUE (default), any existing file at the destination is archived before the restore. If FALSE, the function stops if the destination already exists.

archive_dir

Name of the archive subdirectory. Defaults to "archive".

Value

Invisibly returns the path to the restored file, or NULL on failure.
