Engineering Lakehouses with Open Table Formats
By :
The need for interoperability among open lakehouse formats (i.e., Iceberg, Hudi, and Delta Lake) stems from their distinct origins and the unique design trade-offs they embody. Each format originated in different contexts to address specific problems. This means there are distinctive features in each of these formats. The other perspective is that, although these formats started with different use cases, they ultimately have one common goal: serving as the metadata layer on top of existing data file formats such as Apache Parquet. So, in a technical sense (as we learned from our previous chapters), although each format has a different metadata design, the content of the metadata is very similar. This has been one of the most important considerations in the design of interoperability solutions that we will explore in our next section.
Now, let’s understand the critical needs for interoperability in a bit of detail:
