National-Scale Exadata RAC, DPI Telemetry & Subscriber Intelligence
Tier-1 telecommunications carriers generate 25B-26B daily Deep Packet Inspection (DPI), Call Detail Record (CDR), and RAN events across 50M+ subscribers. We tune bare-metal 10-node Oracle Exadata RAC estates and replace OOM-prone JVM/Spark ingestion clusters with zero-copy C++/PyArrow streaming.
- 10-Node Oracle Exadata RAC Deep Tuning: Uncaged +512 trapped hardware threads (+40%
CPU capacity), collapsed
resmgr:cpu quantumwaits by 99.9% via DBRM v5.0, eliminated ~18.6 TB/day of broadcast temp spills, eradicated 100% ofenq: SS& 99.6% ofenq: HVcontention, and cut nightly batch windows by 5.0 hours/day. - Zero-Copy C++/PyArrow Ingestion: Sustains ~300,000 records/sec per worker under 80 MB RAM across 200,000+ daily files (20.5B DPI records/day), cutting EL windows from 14.5h to 3.5h at 1/10th Spark cost.
- AI-Assisted / Agentic Data Development Factory: AI Skills and MCP solutions for Data Engineering, Hybrid Data Vault 2.0 + Kimball architecture, Governance development/audit, and DB Performance Tuning delivering 10x engineering velocity.
