Struct CatalogSpec 

pub struct CatalogSpec {
    pub url: String,
    pub sample_records: usize,
}

Available on crate feature catalog only.

The top-level catalog: block: opts a faucet run / schedule / replicate pipeline into recording the Data Movement Catalog after every successful root invocation. faucet serve records into its --history backend automatically — this block is for the non-serve runtimes (and for faucet catalog, which reads the same store).

Fields

url: String

Where the catalog is stored: sqlite:<path> (e.g. sqlite:./faucet-catalog.db), a postgres://… URL, or memory (process-lifetime only — useful for tests). SQL backends require the matching serve-history-sqlite / serve-history-postgres build feature. Point faucet serve --history at the same URL to browse the accumulated catalog in the control plane + web console.

sample_records: usize

How many records to sample per run for schema inference (per side). The sample bounds memory; the schema timeline only ever stores the inferred schema, never the records.
