This curriculum spans the technical depth and operational breadth of a multi-workshop program on data compression, comparable to an internal capability build for large-scale data platforms, covering algorithm selection, distributed processing integration, real-time pipeline optimization, and governance—mirroring the complexity of compression practices in modern data mining infrastructures.

Module 1: Foundations of Data Compression in Analytical Workflows

  • Select compression algorithms based on data access patterns—favoring speed for real-time analytics or ratio for archival storage.
  • Integrate compression into ETL pipelines without introducing bottlenecks during transformation phases.
  • Assess trade-offs between CPU overhead and I/O reduction when applying compression at ingestion points.
  • Configure columnar storage formats (e.g., Parquet, ORC) with appropriate compression codecs per column data type.
  • Implement schema-aware compression by analyzing data cardinality and value distribution before encoding.
  • Monitor decompression latency in query execution plans to detect performance degradation in reporting systems.
  • Design fallback mechanisms for systems that cannot natively handle compressed intermediate data formats.

Module 2: Lossless vs. Lossy Compression in Data Mining Contexts

  • Determine acceptable precision loss in numerical attributes when applying lossy techniques like quantization in high-dimensional datasets.
  • Apply delta encoding on time-series sensor data and validate reconstruction accuracy against original signals.
  • Use dictionary-based compression (e.g., LZ77) for categorical text fields while preserving label integrity for downstream classification.
  • Implement run-length encoding on sparse binary flags and measure impact on model training efficiency.
  • Evaluate entropy coding (Huffman, arithmetic) on skewed distributions to optimize storage in frequent itemset mining.
  • Establish thresholds for signal-to-noise ratio when compressing image or audio data used in multimodal mining tasks.
  • Document and audit data transformations introduced by lossy methods to maintain reproducibility in research workflows.

Module 3: Compression in Distributed Data Processing Frameworks

  • Configure Hadoop MapReduce jobs to use LZO or Snappy for intermediate outputs to balance network transfer and CPU cost.
  • Enable block-level compression in HDFS and align block sizes with codec characteristics to avoid partial decompression penalties.
  • Adjust Spark shuffle behavior by selecting compressible serialization formats (e.g., Kryo) and tuning compression levels.
  • Manage codec compatibility across cluster nodes to prevent deserialization failures during job execution.
  • Prefer splittable formats (e.g., bzip2, LZO) over non-splittable (e.g., gzip) for large files processed in parallel.
  • Monitor shuffle spill rates before and after enabling compression to quantify improvements in disk and network utilization.
  • Implement compression-aware partitioning strategies to prevent data skew from unevenly compressed segments.

Module 4: Indexing and Query Performance with Compressed Data

  • Build secondary indexes on compressed columns by extracting metadata during compression to support predicate pushdown.
  • Optimize B-tree index structures for compressed variable-length fields using prefix truncation and suffix omission.
  • Enable zone maps or min/max statistics in columnar databases to skip decompressing irrelevant data blocks.
  • Measure query response time differences when using compressed vs. uncompressed fact tables in OLAP cubes.
  • Implement late materialization to delay decompression until after filtering operations in query execution.
  • Configure buffer pool behavior in databases to account for compressed page sizes and reduce memory pressure.
  • Use adaptive compression where frequently accessed data is stored in lighter compression formats for faster retrieval.

Module 5: Compression in Real-Time and Streaming Data Pipelines

  • Select streaming-optimized codecs (e.g., Snappy, LZ4) for Kafka message payloads to minimize end-to-end latency.
  • Implement per-message compression negotiation between producers and consumers based on topic-level policies.
