NOT ON THE CURRENT EDITION
This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar. Understand more

在可用的开放表格格式中,能够支持数据湖仓一体(lakehouses)架构——例如 Apache IcebergDeltaHudi——尚未出现明显的赢家。相反,我们看到了一些工具正在促进这些格式之间的互操作性。例如, Delta UniForm 通过允许 Hudi 和 Iceberg 客户端读取 Delta 表,实现了单向互操作性。另一个新进入这个领域的是Apache XTable™,这是一个 Apache 孵化器项目,旨在实现 Hudi、Delta 和 Iceberg 之间的全向互操作性。与 UniForm 类似,XTable 在不创建底层数据副本的情况下,能够在这些格式之间转换元数据。XTable 对于那些在多个表格格式之间进行实验的团队可能会很有用。然而,考虑到这些格式之间功能的差异,长期依赖全向互操作性可能会导致团队只能使用功能的“最小公倍数”。
