Even with feature parity as the north star, depending on the size of your data and complexity of the data processing pipelines you could be looking at a multi-month, maybe even multi-quarter project for phase one—which is a lifetime in tech years. This could include FAQs, custom tooling, common libraries or data schemas.

To mitigate this, in Python v2, we replaced the intermediate processing batches with Parquet storage and loaded the table once into the database, rather than after each batch. This strategy dramatically reduced processing time and network costs. Our answer to this challenge lay in big data processing.

This problem is not new in data processing. Although the Kafka Streams library is “data schema agnostic” today and therefore cannot leverage many standard techniques from the query processing literature, such as predicate pushdown, there is still a large optimization room on structural topology formation for it to explore.

Data Storage: The next step after data ingestion is to store it in HDFS or a NoSQL database such as HBase. HBase storage is ideal for random read/write operations, whereas HDFS is designed for sequential processes. Data Processing: This is the final step in deploying a big data model.
