Google Cloud Storage CSV connector details

The Google Cloud Storage CSV materialization connector in Estuary writes delta updates from Estuary collections into CSV files in a Google Cloud Storage bucket. Updates are batched within Estuary, converted to RFC 4180-compatible CSV, compressed with Gzip, and uploaded to GCS at a configurable interval.

Materializes delta updates from Estuary collections as CSV files
Gzip-compressed output written as .csv.gz files
Configurable upload interval, with a default of 5 minutes
Configurable file-size limit, defaulting to approximately 10 GiB
Optional GCS object prefix for organizing materialized files
Configurable destination path for each Estuary collection
Optional CSV header suppression
Google Cloud service account authentication
Requires the service account to have **roles/storage.objectCreator** permission on the destination bucket

Each Estuary collection produces a sequence of separate CSV files rather than a single continuously updated file. Files use monotonically increasing, zero-padded names so they remain lexicographically sortable, and a new version path is created when a binding is re-backfilled.
