Custom JDBC Driver for Seamless API Data Connectivity
Even though most enterprises increasingly rely on API-driven ecosystems, most BI tools cannot natively interpret JSON-based REST outputs. For one of our clients, this gap resulted in inconsistent analytics workflows, heavy manual intervention, and performance bottlenecks. Seasia Infotech engineered a high-performance custom JDBC driver using the Simba SDK to enable BI tools to query API data just like a relational database.
Overview
Simba JDBC is a custom-built data connector designed to bridge the gap between REST APIs and analytics platforms. The client required a unified, secure, and scalable JDBC driver capable of reading API-generated JSON and exposing it as schema, tables, and columns that make API data behave like a fully query-able database.
The solution was engineered to load data only when required, ensuring high performance, reduced memory consumption, and smooth connectivity with popular BI tools.

Project Scope & Challenges
- APIs return JSON, not relational tables, making it impossible for BI tools to interpret data directly.
- Mapping complex & nested JSON structures into schema → tables → columns required custom logic.
- Performance bottlenecks emerged due to large API payloads and inefficient full-response loading.
- Lack of query pushdown led to excessive data transfer and slow analytics workflows.
User requirement: connect BI tools to REST APIs with the same ease as connecting to MySQL or Postgres.
Seasia’s Solution
Seasia engineered a robust and optimized JDBC driver using the Simba SDK, purpose-built for reading JSON responses from REST APIs.
Highlights of Our Solution
Built a custom JDBC driver that directly consumes REST API data.
Converted JSON nodes into relational structures (schemas, tables, columns).
Implemented on-demand loading so only required data is fetched during query execution.
Developed custom parsing and metadata detection for fields, types, hierarchies, and nested elements.
Optimized performance by eliminating unnecessary API calls and avoiding full payload downloads.
Ensured seamless integration with Tableau and other leading BI tools.
