conductor-oss/conductor

Conductor is a workflow orchestration platform that manages the execution of distributed tasks and complex workflows. It provides a flexible execution engine supporting multiple task types, including human-in-the-loop, AI/LLM integration, and event-driven automation. The system is designed for high scalability and reliability, offering pluggable backends for persistence (PostgreSQL, MySQL, Cassandra, SQLite), indexing (Elasticsearch, OpenSearch), and messaging (Kafka, RabbitMQ, NATS, SQS). It exposes a comprehensive API via REST and gRPC, enabling developers to define, monitor, and control workflow lifecycles with fine-grained control over concurrency, rate limiting, and state management.

This period focused on modernizing the Conductor codebase by migrating from legacy Jersey-based REST APIs and custom configuration systems to a Spring Boot architecture with gRPC support. Significant changes included removing outdated HTTP clients, Redis persistence modules, and contrib modules, while introducing new service layers, event-driven workflows, and comprehensive validation logic.

This period focused on modernizing the Conductor server by migrating to Spring Boot, which standardized configuration and bean management across all persistence modules. The team expanded backend support by adding MySQL, PostgreSQL, and Elasticsearch 7 implementations, while also introducing external storage options for AWS S3, Azure Blob, and PostgreSQL. Additionally, the codebase introduced new system tasks for HTTP and JSON transformations, alongside comprehensive test coverage for the new architecture.

57 changes

This period focused on expanding Conductor's backend flexibility by adding support for SQLite, Cassandra, and multiple message queue systems (Kafka, NATS, RabbitMQ), alongside a new file storage subsystem. Concurrently, the codebase integrated AI capabilities through an agentspan module and SDK annotations, while significantly broadening test coverage across these new features and existing core components.
