Jumpstart: Your Introduction to MongoDB
Download as PPTX, PDF2 likes479 views
The document is an introduction to MongoDB, a cross-platform and open-source document-oriented NoSQL database. It covers topics including MongoDB's document model, query language, replication, sharding, and deployment considerations for sysadmins and DevOps. The session emphasizes MongoDB's advantages such as dynamic schemas, high availability, and ease of use for various applications.

Jumpstart: Your Introduction to MongoDB
- 1. #MDBW17 @jaydestro Your Introduction To MongoDB Jumpstart!
- 2. #MDBW17 Who is this guy?
- 3. #MDBW17 Why am I here? I love waking up early. or... You are ready to start your MongoDB World Experience!
- 4. #MDBW17 Agenda • Document Model • Query Language • Compatibility • MongoDB Components • SysAdmin/DevOps - Implementation
- 5. #MDBW17 What color is this dress?
- 6. #MDBW17
- 8. #MDBW17 The webservers… not so happy.
- 9. #MDBW17 What did I learn? ● People like dresses ● People LOVE sharing opinions ● The webservers were not efficient ● MongoDB withstood the traffic ● MongoDB was perfect for voting app
- 10. #MDBW17
- 11. Enough about me.
- 12. #MDBW17 OK, so what is MongoDB? MongoDB is a cross-platform and open-source document-oriented database, a kind of NoSQL database. As a document database, MongoDB shuns the relational database's table-based structure to adapt JSON-like documents that have dynamic schemas which it calls BSON.
- 13. #MDBW17 OK, so what is MongoDB? ● Written in C++, C and JavaScript. ● Source and binary packages available for download on mongodb.com/download ● Affero GPL License ● Ready for Cloud or Bare Metal Environments
- 14. #MDBW17 OK, so what is MongoDB? MongoDB was written to make it simple to store data. {"Key": "Value"} Create dynamic schemas for your data. Model your data based on your app.
- 15. #MDBW17 More than just key-value var LocationSchema = new Schema({ name: String, loc: { type: [Number], // [<longitude>, <latitude>] index: '2d' // create the geospatial index } }); Create dynamic schemas for your data. Model your data based on your app.
- 16. Document Model
- 17. #MDBW17 We're talkin' about documents
- 18. #MDBW17 We're talkin' about documents
- 19. #MDBW17 We're talkin' about documents
- 20. #MDBW17 Rich data similar to JSON
- 21. #MDBW17 BSON - Binary JSON ● Binary serialization JSON data representation! ● Easier to transfer than text files. ● Lightweight, transversable, efficient.
- 22. Query Language
- 27. #MDBW17 Indexes support the efficient execution of queries in MongoDB. Without indexes, MongoDB must perform a collection scan Without an index, MongoDB must perform a collection scan. (Look at every doc for results) Indexes
- 28. #MDBW17 • Single Field • Multikey • Text • Geospatial • Hashed • Compound Indexes Types
- 29. #MDBW17 A framework for data aggregation modeled on the concept of data processing pipelines. Documents enter a multi-stage pipeline that transforms the documents into aggregated results. Aggregation Pipeline
- 30. #MDBW17 Reduce the CPU cycles in processing your app, let MongoDB handle aggregation. Results produced from aggregation lower in total byte size of your data, saving bandwith. Aggregation Pipeline
- 31. #MDBW17 bash-3.2$ ps auxwww | grep mongod.conf | awk '{ print $2 }' 39087 41024 Think about a UNIX pipeline, stages.
- 33. Compatibility
- 37. #MDBW17 A replica set in MongoDB is a group of mongod processes that maintain the same data set Replica sets provide redundancy and high availability, and are the basis for all production deployments. Replica sets - Reliability
- 39. #MDBW17 Our primary has failed PRIMARY SECONDARY SECONDARY DRIVER APPLICATION
- 40. #MDBW17 Election of new primary FAILED SECONDARY DRIVER APPLICATION SECPMNDA PRIMARYSECONDARY
- 43. #MDBW17 Sharding is a method for distributing data across multiple machines. MongoDB uses sharding to support deployments with very large data sets and high throughput operations. Sharding - Throughput and data distro
