MongoDB .local Munich 2019: MongoDB Atlas Data Lake Technical Deep Dive
1 like284 views
The document discusses MongoDB Atlas Data Lake, emphasizing its design goals to efficiently manage and query vast amounts of data stored in various formats. It outlines the architecture, implementation requirements, and configuration process for creating an Atlas Data Lake, as well as how users can query and analyze long-term data using MongoDB Query Language (MQL). Future improvements and additional features are also mentioned, indicating a roadmap for enhancing the capability and performance of the data lake.

- 7. Design Goals and Requirements
- 9. #MDBLocal MongoDB Wire Protocol Support Requirements 1) Look and act like MongoDB Solution Empty • Implement a TCP server in Go. • Used mongo-go-driver’s wireprotocol packagey • Used mongo-go-driver's bson package • Read only
- 10. #MDBLocal MongoDB Security Model Requirements 2) Access customer’s data securely. Solution Empty • Users configured in MongoDB Atlas • Same authentication and authorization • Configure buckets
- 11. #MDBLocal Scalable Processing Requirements 3) Handle long running queries over vast amounts of data using resources efficiently Solution Empty • Read-only commands • Use server’s aggregation engine • Distributed MQL processing • Intelligent file targeting
- 12. #MDBLocal Data Formats Requirements 4) Support a variety of data formats Solution Empty • Avro (gzipped) • Parquet • BSON/ JSON (gzipped) • CSV/TSV (gzipped)
