Controls how datasets are exposed to queries
Hudi supports the following views of stored data
Excerpt Include read optimized view read optimized view - incremental view : Queries on this view only see new data written to the dataset, since a given commit/compaction. This view effectively provides change streams to enable incremental data pipelines.
- realtime view : Queries on this view see the latest snapshot of dataset as of a given delta commit action. This view provides near-real time datasets (few mins) by merging the base and delta files of the latest file slice on-the-fly.
Following table summarizes the trade-offs between the different views.
| Trade-off | ReadOptimized | RealTime |
|---|---|---|
| Data Latency | Higher | Lower |
| Query Latency | Lower (raw columnar performance) | Higher (merge columnar + row based delta) |
