Plugin configurationOverview #
The Hacker News Source plugin for CloudQuery extracts configuration from the Hacker News API and loads it into any supported CloudQuery destination (e.g. PostgreSQL, BigQuery, Snowflake, and more).
It can be used for real applications, but is mainly intended to serve as an example of CloudQuery Source plugin with an incremental table.
Configuration #
The following configuration syncs from Hacker News to a Postgres destination, using a special table (
cq_hackernews_state) to store the state of the last sync. It is also possible to any other CloudQuery destination as a state backend. For more on this, see Managing Incremental Tables.The (top level) source spec section is described in the Source Spec Reference. The config for the
postgresql destination is not shown here. See our Quickstart if you need help setting up the destination.kind: source

spec:
item_concurrency: 100item_concurrency(integer) (optional):The number of items to fetch concurrently. Defaults to100.start_time(string) (optional):A date-time string inRFC3339format. For example,"2023-01-01T00:00:00Z"will sync all items created on or after January 1, 2023. If not specified, the plugin will fetch all items.Note that because this is an incremental table, a previous cursor position will take precedence over this setting, unless the given start time is after the last cursor position.
