Announcing fixSQL v1.1: Apache Iceberg Support

7 April 2026 · Atomic Wire Team

fixSQL 1.1 adds support for writing FIX datasets as Apache Iceberg tables on cloud object storage, enabling users to query the data using the query engine of their choice.

Iceberg is an open table format. Once a dataset is written, it can be queried directly from any Iceberg-compatible SQL engine, including BigQuery, Databricks, and Snowflake, with no copying or conversion involved. Each team or user can pick the engine that best fits the workload at hand, whether that is interactive exploration, scheduled reporting, or large-scale analytics.

Because the data lives in shared object storage rather than on an individual machine, multiple users can read the same dataset concurrently.

Highlights in v1.1 include:

  • Remote storage of FIX datasets as Apache Iceberg tables on cloud object storage
  • Bring-your-own query engine: BigQuery, Databricks, Snowflake, or any other Iceberg-compatible engine
  • Concurrent multi-user access to shared datasets
  • Open, vendor-neutral storage that doesn't tie data to any particular query engine
