sink

Stdout / stderr sink (JSON Lines, pretty, TSV)

Install

cargo install faucet-cli --features sink-stdout
faucet init --sink stdout
# Cargo.toml — use it as a library
cargo add faucet-sink-stdout

Starter config

sink:
  type: stdout
  config:
    # destination: null    # Which standard stream to write records to.
    # format: null    # How each record should be serialized before writing.
    # flush_per_record: false    # Flush the underlying writer after every record instead of at batch boundaries.
    # max_records: null    # Stop writing after this many records have been emitted.
    # batch_size: 1000    # Records per upstream `StreamPage`.

Config fields

FieldTypeDefaultDescription
destination object stdout Which standard stream to write to.
format object json_lines Output format.
flush_per_record boolean false Flush the underlying writer after every record instead of at batch boundaries. Tradeoff: lower latency for live preview, slightly lower throughput.
max_records integer — Stop writing after this many records have been emitted. Subsequent write_batch calls become no-ops. None means unlimited.
batch_size integer 1000 Records per upstream StreamPage. The stdout sink writes records to the chosen standard stream one at a time through a buffered writer, so this field has **no behavioural impact** at the sink — it is exposed purely for config parity across every sink in the workspace. Defaults to DEFAULT_BATCH_SIZE.
