| Both Avro and Delta Lake can be used for streaming and real-time processing. | ||

| Avro is often used for ingestion of raw streaming data, such as log files, events or sensor data. Its lightweight, row-based structure makes it ideal for high-throughput writes. |
There was a problem hiding this comment.
I would remind the reader here again that avro is row-based.
The row-based format lends itself better for initial ingestion, but because it is not a columnar format, there is a higher cost when using avro for analytical stream processing.
On a side note, I've been bit by avro and streaming. Spark provides better support for permissive-mode now, but ArrayIndexOutOfBoundsException's used to plague my days on PagerDuty. While it "can be forwards-compatible" - when it isn't it hurts :)
