This curriculum spans the design and operational rigor of a multi-workshop program on industrial-scale data platforms, covering the breadth of decisions and trade-offs encountered in building and maintaining secure, observable, and cost-effective data pipelines across batch and streaming contexts.

Module 1: Architecting Scalable Data Ingestion Pipelines

  • Choose between batch and streaming ingestion based on SLA requirements and downstream latency tolerance.
  • Implement idempotent consumers in Kafka to handle duplicate messages during retries without corrupting data.
  • Design schema evolution strategies using Avro with compatibility rules to support backward and forward reading.
  • Configure backpressure handling in Spark Streaming to prevent executor OOM errors during traffic spikes.
  • Select appropriate serialization formats (e.g., Parquet vs. JSON) based on query patterns and storage cost.
  • Integrate change data capture (CDC) tools like Debezium with transactional databases for real-time replication.
  • Deploy ingestion pipelines with infrastructure-as-code (Terraform) to ensure reproducible environments.
  • Monitor ingestion lag using Kafka consumer group metrics and trigger auto-scaling of consumers.

Module 2: Distributed Storage Design for Big Data

  • Partition large datasets by time and entity key to optimize query performance and lifecycle management.
  • Choose between HDFS and cloud object stores (S3, ADLS) based on cost, durability, and compute integration.
  • Implement tiered storage policies to move cold data from hot to archive tiers automatically.
  • Configure replication factors in HDFS balancing fault tolerance against storage overhead.
  • Design metadata management for Parquet files using Hive Metastore or AWS Glue Catalog.
  • Enforce file size targets (128MB–1GB) during writes to prevent small file problems in HDFS.
  • Use erasure coding in HDFS for cold data to reduce storage footprint by 50% compared to replication.
  • Implement object locking and versioning in S3 to meet compliance requirements for data immutability.

Module 3: Data Transformation at Scale

  • Optimize Spark DAGs by minimizing wide transformations like groupBy and join to reduce shuffling.
  • Use broadcast joins for small lookup tables to avoid expensive shuffle operations.
  • Configure dynamic allocation and speculative execution in Spark to handle straggler tasks.
  • Implement data skew mitigation using salting techniques on high-cardinality keys.
  • Select appropriate file formats (Parquet, ORC) with compression (Snappy, Zstandard) for storage efficiency.
  • Write deterministic transformations to ensure reproducibility across job runs.
  • Use delta lake upserts with merge operations to handle slowly changing dimensions.
  • Validate data quality during transformation using embedded assertions and fail-fast logic.

Module 4: Data Quality and Observability

  • Define and monitor freshness SLAs for critical datasets using timestamp checks in orchestration tools.
  • Instrument data pipelines with structured logging to enable root cause analysis during failures.
  • Implement anomaly detection on row counts and null rates using statistical baselines.
  • Deploy data profiling jobs to track schema drift and unexpected data type changes.
  • Set up alerting on data quality rules (e.g., PII leakage, invalid enums) using Great Expectations or custom checks.
  • Integrate lineage tracking with tools like OpenLineage to map field-level data flow.
  • Use synthetic test data to validate pipeline behavior during deployment rollouts.
  • Log data quality metrics to a central warehouse for audit and trend analysis.

Module 5: Security and Access Governance

  • Implement column- and row-level security in query engines (e.g., Presto, Snowflake) using Ranger or native policies.
  • Manage secrets for data sources using HashiCorp Vault instead of hardcoding in pipeline configs.
  • Enforce encryption at rest and in transit for all data movement and storage components.
  • Assign least-privilege IAM roles to data processing jobs to limit blast radius of compromise.
  • Conduct periodic access reviews for data lake roles and revoke stale permissions.
  • Mask sensitive fields (e.g., SSN, email) in non-production environments using deterministic tokenization.
  • Log all data access attempts for audit purposes, especially for PII-containing tables.
  • Integrate data classification tools to auto-tag datasets based on content (e.g., PCI, PHI).

Module 6: Orchestration and Workflow Management

  • Model dependencies in Airflow DAGs using explicit task relationships and avoid implicit assumptions.
  • Implement sensor patterns to trigger pipelines on external events (e.g., file arrival, API callback).
  • Use backfill strategies with caution to avoid overwhelming downstream systems with historical data.
  • Parameterize workflows to support multi-environment deployment (dev, staging, prod).
  • Set task retries with exponential backoff and circuit breaker logic to prevent cascading failures.
  • Monitor DAG run durations and alert on deviations from historical baselines.
  • Version control DAG definitions and couple them with CI/CD pipelines for deployment safety.
  • Use sub-DAGs or TaskGroups to modularize complex workflows and improve maintainability.

Module 7: Performance Tuning and Cost Optimization

  • Right-size cluster resources based on historical utilization metrics from monitoring tools.
  • Use spot instances for fault-tolerant batch workloads to reduce compute costs by up to 70%.
  • Precompute aggregations for frequently accessed metrics to reduce query latency.
  • Implement data compaction jobs to merge small files and improve scan efficiency.
  • Cache frequently accessed datasets in memory or SSD-backed storage layers.
  • Analyze query execution plans to identify expensive operations (e.g., full table scans).
  • Set up auto-termination for idle clusters to prevent unnecessary billing.
  • Compare cost per query across engines (e.g., Athena vs. Redshift) for workload-specific decisions.

Module 8: Real-Time Processing and Stream Analytics

  • Choose windowing strategies (tumbling, sliding, session) based on business use case semantics.
  • Handle late-arriving data in Flink or Spark Structured Streaming using watermarking and allowed lateness.
  • Implement exactly-once processing semantics using two-phase commit or transactional sinks.
  • Scale Kafka consumer groups dynamically based on lag and message throughput.
  • Use stateful processing for sessionization or running aggregates with TTL management.
  • Deploy stream processing jobs in high-availability mode with checkpointing enabled.
  • Monitor end-to-end latency from source to sink to ensure SLA compliance.
  • Test stream applications with replayable topics to validate logic under production data.

Module 9: Data Lifecycle and Retention Management

  • Define retention policies per dataset based on regulatory requirements and business value.
  • Automate data archival using lifecycle rules in cloud storage (e.g., S3 Glacier transitions).
  • Implement soft-delete patterns with tombstone markers before physical deletion.
  • Coordinate deletion across replicated systems to maintain consistency during purge operations.
  • Log all data deletion activities for audit and compliance verification.
  • Validate referential integrity before dropping partitioned datasets with dependencies.
  • Use metadata tagging to classify data by sensitivity and retention class.
  • Conduct quarterly reviews of retention policies to align with evolving legal standards.
