R2 – R2 Data Catalog table-level compaction

You can now enable compaction for individual Apache Iceberg tables in R2 Data Catalog, giving you fine-grained control over different workloads.

# Enable compaction for a specific table (no token required)
npx wrangler r2 bucket catalog compaction enable <BUCKET> <NAMESPACE> <TABLE> --target-size 256

This allows you to:

• Apply different target file sizes per table
• Disable compaction for specific tables
• Optimize based on table-specific access patterns
