Figure 1. Apache Hudi ingests change logs, events and incremental streams to serve different use cases by exposing different views on the table.
Figure 2. Hudi’s copy-on-write feature enables us to perform file level updates, improving data freshness drastically.
Figure 3. The Apache Hudi team at Uber developed a data compaction strategy for merge-on-read tables to convert recent partitions in a columnar format frequently, thereby limiting query side compute cost.
Figure 4. Apache Hudi use cases include data analytics and infrastructure health monitoring.
