Product Update: April 2026

This month's releases focus on getting data in faster, speeding up deploys, and adding source versioning for SQL Server. Here are some of the highlights; for the full list of changes, see the release notes.

• S3 and bulk data loading. You can now load CSV and Parquet files directly from Amazon S3. COPY FROM supports both formats from any S3-compatible storage, including Google Cloud Storage, Cloudflare R2, and MinIO, so wherever your data lives, it's faster and easier to get it into Materialize.
• Faster catalog operations and deploys. Creating views and indexes and dropping objects is now 37-55% faster, even in environments with hundreds or thousands of objects, and batching multiple operations in a single transaction brings further gains of up to 10%. Blue/green deploys via dbt-materialize now batch readiness checks instead of polling clusters one by one, so you spend less time waiting on deploys.
• SQL Server source versioning (private preview). Source versioning is now available for SQL Server, so you can handle upstream schema changes without recreating your sources.
• Performance and efficiency improvements. Several improvements, including up to 25% lower memory for joins on varchar and text columns, incremental WebSocket streaming, and faster Iceberg sink commits.
