Amazon S3 Tables now allow up to 100 table buckets per AWS Region per account, a significant increase from the previous limit of 10. This supports creation of up to 1 million tables per region, enabling customers to segregate datasets by workload or team, and to apply granular bucket-level policies like encryption and replication independently.
S3 Tables combine cloud object storage with integrated Apache Iceberg support to optimize query efficiency and storage costs over time automatically. This quota increase facilitates large-scale, organized data lakes and analytic workloads by providing enhanced structural flexibility. The increase applies by default to all accounts and regions where S3 Tables are available.
