Description

This curriculum spans the technical and organizational complexity of a multi-workshop program focused on enterprise data platform modernization, comparable to advisory engagements that address data governance, infrastructure migration, and scalable analytics delivery across distributed systems.

Designing multi-region replication strategies for disaster recovery while minimizing cross-region egress costs.
Implementing data retention policies that align with legal hold requirements and storage cost optimization.
Negotiating SLAs with infrastructure providers for data durability, availability, and repair time objectives.
Planning for incremental data migration from legacy EDWs to modern data platforms with zero downtime.

Module 2: Scalable Data Ingestion Architecture

Choosing between batch, micro-batch, and streaming ingestion based on source system capabilities and downstream latency needs.

Optimizing shuffle partitions based on data volume and cluster node count to avoid skew and OOM errors.
Choosing between DataFrame, Dataset, and RDD APIs based on type safety and optimization needs.
Implementing broadcast joins for small lookup tables to reduce shuffle traffic.
Configuring checkpointing intervals for long-running streaming jobs to balance recovery time and storage cost.
Managing Python UDF serialization overhead in PySpark using vectorized Pandas functions.
Deploying Flink applications with savepoints for stateful processing and version upgrades.
Monitoring GC pressure and spill-to-disk events to diagnose performance bottlenecks in processing jobs.

Module 5: Data Quality and Observability

Defining data quality rules (completeness, consistency, accuracy) per domain with business stakeholder sign-off.
Integrating Great Expectations or Deequ into CI/CD pipelines for data test automation.
Setting up anomaly detection on data volume, freshness, and distribution drift using statistical baselines.

Creating data lineage graphs using metadata extraction from ETL jobs and query logs.
Alerting on SLA breaches for pipeline completion time using time-series monitoring tools.
Implementing data profiling jobs to detect unexpected null rates or value outliers in staging layers.
Establishing data incident response protocols with escalation paths and remediation runbooks.

Module 6: Security and Compliance Governance

Implementing column- and row-level security in Snowflake or Databricks using dynamic masking policies.
Enforcing attribute-based access control (ABAC) integrated with corporate identity providers.
Auditing data access patterns using query logs to detect unauthorized PII exposure.
Classifying data sensitivity levels using automated scanners and tagging frameworks.
Managing encryption keys for data-at-rest using customer-managed KMS with rotation policies.
Conducting data protection impact assessments (DPIAs) for new data collection initiatives.
Implementing data anonymization techniques (k-anonymity, differential privacy) for regulated analytics.
Documenting data processing agreements (DPAs) for third-party data sharing under GDPR or CCPA.

Module 7: Performance Optimization and Cost Control

Right-sizing cluster configurations based on historical utilization metrics and auto-scaling policies.
Implementing query result caching for frequently accessed reports with cache invalidation rules.
Converting cold data to cheaper storage tiers (S3 Glacier, Azure Archive) with retrieval time SLAs.
Optimizing file sizing and compaction strategies to reduce small file overhead in data lakes.
Using materialized views to pre-aggregate high-latency queries on large datasets.
Enforcing query timeouts and resource quotas to prevent runaway jobs in shared clusters.
