- MongoDB is well-suited for systems of engagement that have demanding real-time requirements, diverse and mixed data sets, massive concurrency, global deployment, and no downtime tolerance. - It performs well for workloads with mixed reads, writes, and updates and scales horizontally on demand. However, it is less suited for analytical workloads, data warehousing, business intelligence, or transaction processing workloads. - MongoDB shines for use cases involving single views of data, mobile and geospatial applications, real-time analytics, catalogs, personalization, content management, and log aggregation. It is less optimal for workloads requiring joins, full collection scans, high-latency writes, or five nines u

Use cases where MongoDB shines MongoDB is less good for • Search engine • Slicing and dicing of data in unplanned ways requiring joins and full scans • Nanosecond latency writing (real time tick data) • Uptime beyond 99.999%, instant failover • Batch processing Text indexing only for elementary uses Classic DW usage. MongoDB needs known query pattern. Specialty DBs like Kdb are built for this Requires failover in <1s That’s what Hadoop is for…. Note: transaction processing does not require database transactions. Move money from account A to account B is never instantaneous and requires actual processing…. Usually in batch

- 37. Technical: Why MongoDB • High performance (1000’s – millions queries / sec) - reads & writes • Need flexible schema, rich querying with any number of secondary indexes • Need for replication across multiple data centers, even globally • Need to deploy rapidly and scale on demand (start small and fast, grow easily) • 99.999% availability • Real time analysis in the database, under load • Geospatial querying • Processing in real time, not in batch • Need to promote agile coding methodologies • Deploy over commodity computing and storage architectures • Point in Time recovery • Need strong data consistency • Advanced security

Editor's Notes
- #13: Here we have greatly reduced the relational data model for this application to two tables. In reality no database has two tables. It is much more common to have hundreds or thousands of tables. And as a developer where do you begin when you have a complex data model?? If you’re building an app you’re really thinking about just a hand full of common things, like products, and these can be represented in a document much more easily that a complex relational model where the data is broken up in a way that doesn’t really reflect the way you think about the data or write an application.
