Create a temporary sink specification — sink

Like sink_quick() but writes to a run-scoped temporary directory. Perfect for testing and ephemeral workflows that don't need permanent storage.

Usage

sink_temp(
  fields,
  write = "rds",
  read = NULL,
  ext = NULL,
  prefix = "parade-quick",
  template = "{.stage}/{.field}/{.row_key}",
  autoload = FALSE,
  overwrite = c("skip", "overwrite", "error"),
  sidecar = c("json", "none"),
  atomic = TRUE,
  checksum = TRUE,
  ...
)

Arguments

fields: Character vector of field names to persist
write: Format name (e.g., "rds", "csv"), function, or formula for writing
read: Optional function or formula for reading
ext: File extension including dot
prefix: Prefix for temp directory (default: "parade-quick")
template: Glue template for file paths
autoload: Whether to automatically load artifacts
overwrite: Overwrite policy
sidecar: Sidecar metadata format
atomic: Whether to use atomic writes
checksum: Whether to compute checksums
...: Additional arguments

Value

A parade_sink specification object

Examples

# Quick temp sink for testing
tmp_sink <- sink_temp("result", write = "rds")

# CSV temp sink
csv_tmp <- sink_temp("data",
  write = ~ write.csv(.x, .path, row.names = FALSE),
  ext = ".csv"
)

# Will write to tempdir()/parade-quick-<runid>/...
