What it says it does
Apache Spark skill for ETL and data transformation across all versions (3.5 LTS through 4.2). Deep expertise in DataFrame API, Spark SQL, Catalyst optimizer, Structured Streaming, partition tuning, join strategies, and lakehouse integration. WHEN: "Spark", "PySpark", "SparkSQL", "spark-submit", "DataFrame", "RDD", "Catalyst", "Tungsten", "AQE", "Spark Structured Streaming", "Spark partition", "Spark shuffle", "Spark join", "Spark UDF", "Spark performance", "Spark ETL", "Spark pipeline", "spark.conf", "SparkSession". Do NOT use for Databricks-managed features (Unity Catalog, Photon, workspace/cluster administration) -- that's the `databricks` skill in the database plugin. Do NOT use for BI/reporting tool selection or dashboarding on top of Spark output -- that's the analytics plugin.

Put this measurement in your README
A badge carrying how many listings this index holds from the repository and how many pass every static structural check. It reads from this index every time somebody loads your page, so it changes when the measurement changes and there is nothing to keep up to date. Free, no account, and the value is not something you or we can set by hand.
[](https://skillworks.kynth.studio/?q=chrishuffman5%2Fdomain-expert)Would rather not hotlink us? Every badge is also served in shields.io’s endpoint schema, so shields renders the image and your readers never talk to our domain:
Published by Toolproof, the masthead over this index and eight others. The method behind the number is at toolproof.kynth.studio/methodology, and the whole thing is readable as JSON with no key at /api.
