Iceberg Open Table Format is designed for managing large datasets that require fast read performance on a slow and infrequently changing lake. It is not suitable for the high frequency transactional workload.
There is a close to functional parity between the three available Open Table Formats in the industry – Apache Iceberg, Delta Lake, and Apache Hudi. Their ecosystems, developer, and contributor community managed as open-source projects differ and one way to decide on which OTF to choose would be based on the available and supported ecosystem for your use cases. Some customers who are already working in a Databricks environment, choose Delta OTF as it enables seamless integration with Unity catalog and Databricks services. For customers who are using or plan to use analytics engines from other vendors or open source, they would prefer to choose vendor agnostic Iceberg OTF.
