What you'll do
Data Core , a Java / Spring Boot service with gRPC and message-queue APIs.

Implement features and fix bugs in Data Core backend integrations.
Add and fix sqlglot dialect support: parsing, SQL generation, and transpilation correctness.
Investigate StarRocks behavior and compatibility issues, and contribute fixes or workarounds.
