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.

The data processing pipeline characterizes these objects, deriving key parameters such as brightness, color, ellipticity, and coordinate location, and broadcasts this information in alert packets. The data from these detections are then serialized into Avro binary format.

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. How to avoid the same.
