Use Databricks Community Edition or a local Jupyter Notebook with PySpark installed. These environments allow you to write code in Python while leveraging the power of big data engines. 2. Ingesting Data: The "E" in ETL
When working with big data, you don't "loop" through rows. You apply and Actions .
Start with Apache Spark . Unlike its predecessor (Hadoop MapReduce), Spark processes data in-memory, making it significantly faster and more user-friendly.
Operations like .count() or .show() trigger the actual computation.
Only words with 2 or more characters are accepted
Max 200 chars total
Space is used to split words, "" can be used to search for a whole string (not indexed search then)
AND, OR and NOT are prefix words, overruling the default operator
+/|/- equals AND, OR and NOT as operators.
All search words are converted to lowercase.
