Designing batch and streaming integration around correctness, throughput and recovery.

ARCHITECTURE / CONCEPTUAL FLOW
01 / ENGINEERING NOTES
Problem & context
Moving data between distributed processing and operational stores requires more than a fast transformation: retries and schema drift can undermine trust.
Data-platform work spans Spark/Databricks processing, Kafka integration and database-backed downstream consumers.
02 / ENGINEERING NOTES
Constraints
Variable batch sizes, skew, JDBC throughput, downstream load and incomplete source data shape pipeline design.
03 / ENGINEERING NOTES
Engineering decisions
Choose partition boundaries and batch sizes from measured workloads rather than defaults.
Make validation and replay behavior explicit at each handoff.
04 / ENGINEERING NOTES
Reliability & data flow
Design for idempotent reprocessing, bounded retries, checkpoint-aware recovery and monitored data-quality failures.
Source → batch or stream ingest → distributed transformation → validation → serving database or analytics.
05 / ENGINEERING NOTES
Operational model
Watch data freshness, job failures, lag and destination pressure; define ownership for failed records.
06 / ENGINEERING NOTES
Trade-offs
More parallel writes can improve throughput while saturating a database; latency, cost and consistency require balance.
07 / ENGINEERING NOTES
Outcome & next steps
A documented approach to dependable data movement; no throughput or cost improvement is claimed without measurement.
Add workload-specific baselines and automate reconciliation where source contracts permit it.
08 / ENGINEERING NOTES
Key lesson
A pipeline is production-ready when it can explain what happened to every failed batch.
