Developed and delivered a comprehensive disaster recovery guide for self-hosted LangSmith within the langchain-ai/docs repository, focusing on consolidating backup, replication, and recovery procedures across Postgres, ClickHouse, Redis, and blob storage. The work involved creating detailed documentation in Markdown, outlining state inventory, RPO and RTO planning with multiple target profiles, and providing step-by-step guidance for backup, replication, and point-in-time recovery tailored to each data store. The guide also addressed cloud architecture considerations, recommending deployment patterns such as Multi-AZ and cross-region active/passive setups to enhance reliability. Collaboration with other engineers ensured accuracy and clarity throughout the documentation process.
