Definition

#todo verify
Following table summarizes the trade-offs between these two dataset types
| Trade-off | def~copy-on-write | def~merge-on-read |
|---|---|---|
| Data Latency | Higher | Lower |
| Update cost (I/O) | Higher (rewrite entire def~table parquet) | Lower (append to `delta log`) |
| Write Amplification | Higher | Lower (depending on compaction strategy to the def~table parquet) |
