AWS announced on September 30 that Aurora PostgreSQL supports direct querying of Apache Iceberg and Parquet data. This development adds to the existing ecosystem of vendors claiming Postgres can read Iceberg, resulting in at least four distinct implementations with varying compatibility. The clarification highlights the fragmentation in how different vendors interpret this capability.
- Aurora PostgreSQL now queries Iceberg/Parquet directly, expanding data lake access.
- Multiple vendor implementations of 'Postgres reads Iceberg' exist with limited commonality.
- Verify specific implementation details when integrating with other Postgres distributions.
- No additional vendor-specific features are mentioned beyond the direct query capability.
- Fragmentation in Iceberg support means cross-vendor compatibility is not guaranteed.
