CDR Validator

The CDR Validator is designed for telecom data teams who ingest large volumes of Call Detail Records for billing, compliance, and reporting. It applies a schema-driven approach to verify that each record contains required fields, correct data types, and valid values. Conceptually, it treats a CDR as a structured record and checks syntactic and semantic correctness before it enters downstream processes.
Core capabilities include per-record validation, computed charges, and cross-field checks. It supports fields such as call_id, origin, destination, start_time, duration_sec, rate_per_min, currency, and billed_amount, with options for custom mappings and regional rule templates.
Unique value lies in its flexible rule engine, support for batch and streaming processing, and export options for audit trails. Users can define severity levels, generate summaries, and integrate with data lakes or warehouses for end-to-end validation.
Use cases include pre-billing validation, QA reconciliation, and regulatory reporting. Advanced users can enable anomaly detection, currency conversion, and time-zone normalization; overall, the tool improves data quality and accelerates financial close.
