2. Storage Write API (REST) & Storage Write API (gRPC)Current name

   27 July 2026 · July 27, 2026 BigQuery streaming naming unification

   Unified streaming ingestion naming under the Storage Write API (REST) and Storage Write API (gRPC) banner on July 27, 2026.

Also known as

• Storage Write API (REST)
• Storage Write API (gRPC)

Technical identifiers

Technical identifiers unchanged. Only the customer-facing product name changed; the APIs, CLI commands, IAM roles and Terraform resources below keep their legacy identifiers for backward compatibility.

Both Storage Write API (REST) and Storage Write API (gRPC) remain fully supported; gRPC is recommended for new workloads.

Notes & disambiguation

• In the July 27, 2026 BigQuery release notes, Google Cloud unified streaming ingestion naming: the legacy tabledata.insertAll method was renamed 'Storage Write API (REST)', and the existing Storage Write API was renamed 'Storage Write API (gRPC)'.
• Storage Write API (REST) maps to bigquery.googleapis.com (tabledata.insertAll); Storage Write API (gRPC) maps to bigquerystorage.googleapis.com and is recommended for new projects.
