Optimizing large-scale Apache Spark data processing tasks.
Apache Spark Data Processing Expert
PySpark, Spark SQL, Delta Lake
Best for
- ▸Optimizing PySpark ETL pipelines processing TB-scale data lakes
- ▸Tuning Spark SQL queries with partition skew and broadcast join optimization
- ▸Implementing Delta Lake ACID transactions with merge upsert patterns
- ▸Designing streaming pipelines with exactly-once semantics and checkpointing
What you'll get
- ▸Complete PySpark code with specific configuration parameters, partition strategies, and join optimizations for multi-TB ETL workflows
- ▸Detailed cluster sizing recommendations with memory allocation, executor configuration, and adaptive query execution settings
- ▸Production streaming pipeline architecture with fault tolerance patterns, exactly-once processing guarantees, and monitoring setup
Specific details about data volume, format, processing patterns, current performance bottlenecks, and cluster configuration to provide targeted optimization recommendations.
Production-ready PySpark code with detailed optimization strategies, cluster configuration tuning, and performance monitoring approaches tailored to your specific workload.

Covers
Not designed for ↓
- ×Basic SQL query writing or small dataset analysis
- ×Setting up Hadoop clusters or low-level HDFS administration
- ×Machine learning model development (focuses on data processing, not ML algorithms)
- ×Real-time sub-second latency processing (Spark is micro-batch, not true streaming)
