  • Project mention: Top 10 Common Data Engineers and Scientists Pain Points in 2024 | | 2024-04-11

    Data scientists often prefer Python for its simplicity and powerful libraries like Pandas or SciPy. However, many real-time data processing tools are Java-based. Take the example of Kafka, Flink, or Spark streaming. While these tools have their Python API/wrapper libraries, they introduce increased latency, and data scientists need to manage dependencies for both Python and JVM environments. For example, implementing a real-time anomaly detection model in Kafka Streams would require translating Python code into Java, slowing down pipeline performance, and requiring a complex initial setup.

  • hadoopcryptoledger

    Hadoop Crypto Ledger - Analyzing CryptoLedgers, such as Bitcoin Blockchain, on Big Data platforms, such as Hadoop/Spark/Flink/Hive

  • Project mention: FLaNK AI Weekly 18 March 2024 | | 2024-03-18
  • scotty-window-processor

    This repository provides Scotty, a framework for efficient window aggregations for out-of-order Stream Processing.

  • Project mention: Implementing a “Lookback” Window Using Apache Flink’s KeyedProcessFunction | /r/RedditEng | 2023-10-10

    This concept is similar to a sliding window with a small step size, but with a more memory-efficient implementation. By using “slice sharing” instead of duplicating events into every overlapping window, the memory footprint is reduced. Scotty window processor is an open-source implementation of memory-efficient window aggregations with connectors for popular stream processors like Flink. This is a promising avenue for approximating a “lookback” window when aggregations like count, sum or histogram are required.
