Abstract dell'intervento:
Can we use big data techniques without big data infrastructure? As Java developers, we deal with data processing all the time. We may be analyzing app logs, extracting data from Excel files, copying tables between different databases (simple ETL), etc. Yet, the “standard” Java falls short in processing capabilities when compared to more complex and heavy “big data” solutions like Spark or Flink. This talk will focus on “DataFrame” - an in-memory 2-dimensional table with operations like filtering, column / row transformations, joins, aggregations, etc. I will use an open source DFLib library (https://dflib.org) and Jupyter notebook to demonstrate how to do data processing and visualization in any Java app without much fuss.
