This curriculum spans the technical and operational rigor of a multi-workshop program focused on real-time data platform engineering, covering the full lifecycle of semi-structured data from ingestion and schema governance to storage optimization, secure processing, and integration with analytics systems in distributed environments.
Module 1: Understanding Semi-Structured Data Formats and Their Role in Big Data Ecosystems
- Select JSON over XML for event stream ingestion due to lower parsing overhead and compatibility with modern streaming frameworks.
- Define schema evolution strategies when ingesting Avro data across multiple service versions in a microservices architecture. Implement schema validation using JSON Schema or Protobuf definitions at ingestion points to prevent malformed data propagation.
- Evaluate trade-offs between human readability (JSON) and binary efficiency (Parquet/Avro) in logging pipelines.
- Design nested data structures in JSON to represent hierarchical business entities while minimizing redundancy.
- Standardize timestamp formats across semi-structured logs to ensure consistency in downstream time-series analysis.
- Handle optional and missing fields in JSON payloads by defining default resolution rules in ETL pipelines.
Module 2: Ingestion Patterns for Variable-Schema Data
- Configure Kafka Connect to deserialize JSON payloads and route messages based on dynamic schema identifiers.
- Implement schema-on-read workflows using Spark to process evolving JSON structures without pre-defined tables.
- Use schema registry tools like Confluent Schema Registry to version Avro schemas and enforce backward compatibility.
- Design idempotent ingestion jobs to handle duplicate semi-structured records from unreliable sources.
- Partition raw data landing zones by date and source type to support reprocessing of malformed batches.
- Apply field-level masking during ingestion for sensitive data detected in unstructured JSON payloads.
- Monitor schema drift by comparing incoming JSON field sets against baseline profiles using statistical sampling.
Module 3: Schema Management and Evolution in Distributed Systems
- Enforce schema compatibility policies (backward, forward, full) in a schema registry for Avro-based topics.
- Modify Parquet schema to add nullable columns without invalidating existing partitioned data.
- Map evolving JSON structures to a unified canonical model in the staging layer for cross-source consistency.
- Handle field deprecation by marking columns as inactive in the metadata catalog instead of immediate removal.
- Automate schema migration scripts for Hive metastore when nested fields in JSON are restructured.
- Validate schema changes using automated unit tests that simulate downstream query patterns.
- Negotiate schema change windows with dependent teams to minimize breaking impacts on reporting pipelines.
Module 4: Storage Optimization for Nested and Sparse Data
- Convert frequently queried JSON fields into flattened Parquet columns to improve scan performance.
- Apply dictionary encoding on repetitive string fields within JSON arrays stored in columnar formats.
- Define partitioning strategies for Parquet files based on high-cardinality JSON fields like tenant ID.
- Compress nested JSON blobs using Snappy in HDFS to balance I/O and CPU utilization.
- Set row group sizes in Parquet to optimize predicate pushdown for deeply nested conditions.
- Implement lifecycle policies to archive raw JSON landing data after structured extraction.
- Evaluate Z-Order indexing on multiple JSON-derived columns to accelerate multi-dimensional queries.
Module 5: Querying and Processing Semi-Structured Data at Scale
- Use Spark SQL’s from_json function to parse JSON strings into structured columns with error handling.
- Flatten arrays in JSON using explode() while managing data explosion risks in aggregation jobs.
- Apply schema validation within PySpark pipelines to filter corrupted JSON records before processing.
- Optimize Presto queries on S3-stored JSON by pushing filters into the file scan layer.
- Cache frequently accessed JSON metadata fields in broadcast variables for lookup enrichment.
- Handle schema mismatches during UNION operations by aligning field types using coalesce logic.
- Use Delta Lake’s merge schema feature cautiously when combining JSON-derived tables with divergent structures.
Module 6: Data Quality and Governance for Dynamic Schemas
- Instrument data quality checks to detect unexpected null ratios in critical JSON fields post-ingestion.
- Register JSON-derived datasets in a data catalog with lineage showing source-to-target field mappings.
- Tag sensitive fields identified in JSON payloads (e.g., PII) using automated pattern detection for access control.
- Define data ownership for semi-structured sources by assigning stewardship to originating service teams.
- Generate anomaly alerts when new JSON fields appear in production logs without prior documentation.
- Enforce GDPR-compliant data retention by identifying and purging personal data within nested JSON structures.
- Validate referential integrity between flattened JSON fields and master data registries during ETL.
Module 7: Real-Time Processing of Semi-Structured Streams
- Parse JSON messages in Kafka Streams with error-tolerant deserializers that route malformed data to dead-letter queues.
- Aggregate nested JSON events using session windows to track user behavior across microservices.
- Apply schema validation in Flink pipelines before stateful operations to prevent serialization failures.
- Serialize processed events back to JSON with consistent field ordering for auditability.
- Monitor throughput and latency of JSON parsing stages in real-time pipelines under peak load.
- Implement exactly-once semantics when writing JSON-derived state to external stores using transactional sinks.
- Use JSON Patch operations to propagate incremental updates in event-driven architectures.

- Audit access to raw JSON data stores using centralized logging and alert on anomalous query patterns.
- Implement field-level encryption for sensitive JSON fields using envelope encryption techniques.
- Monitor parsing failure rates in ingestion jobs to detect upstream schema changes or data corruption.
- Generate operational dashboards showing JSON payload size distribution and ingestion latency.
- Respond to schema compliance violations by triggering automated rollback procedures in CI/CD pipelines.
- Conduct forensic analysis on JSON audit logs to reconstruct data lineage during incident investigations.
