MongoDB for the SQL Server Pro MongoDB for the SQL Server Pro Presentation Transcript

  • MongoDB for the SQL Server Pro Lynn Langit Feb 2013 – For MongoDB LA
  • What is MongoDB?• Open source NoSQL database• Document-oriented• Stores JSON-like documents (dynamic schemas)• Includes a strong query language (javascript)• Powerful, flexible indexing (including geospatial)• Sharding and replication• Cross-Platform (many drivers )
  • DemoQUICKSTART - SETUP MONGODB
  • Get MongoDB and Driver(s)• Quick download, zero install• Also get your driver (C# for us)
  • Starting up MongoDB
  • Using the Console
  • Using MongoVue
  • Connecting with MongoVue
  • Using MongoVue
  • Understanding more..COMPARING DOCUMENTDATABASES TO RDBMS SYSTEMS
  • So which type of NoSQL? CAP… CA = SQL/RDBMSCP = noSQL/column SQL Sever / SQLHadoop AzureBig Table OracleH-base MySQLMemCacheDB(graph)? Consistency Availability AP = noSQL/document or key/value Partition MongoDB DynamoDB Tolerance CouchDB Cassandra Voldemort
  • DB Features for MongoDB & SQL Server Large object primary keys support and indexes aggregations queries with like models for SUM(), COUNT sorting / (), etc… limiting results a strong typing system
  • DB Features unique to Document DBs Collections, not Tables Query language, not T-SQL Idrefs, not Joins No pre-defined Schema Aggregations • Aggregation Framework • Grouping or MapReduce No Transactions • No multi-document transactions No Full-text search
  • Use 10gen Quick Reference Cards
  • DB Features of note in MongoDB• BSON supports more complex types (date, geo-spatial, etc…)• Supports dynamic queries via proprietary query language – Uses “find()” which returns a *lazy+ cursor – Multi-key indexes can be created• Scalability via Replication and Sharding
  • Why use MongoDB?Data Structure• Document-like• Semi-structured• Few Joins• GeospatialData Volume• Large or Huge• Distributed• Unpredictable
  • MongoDB Scenarios Document E-commerce Archiving / Management (catalog portion event logging systems only) Real timeanalytics (based Gaming Geospatial on logging) Mobile
  • DemoIMPORTING DATA TO MONGODB
  • Adding Data• Data must be in JSON format - converter• “Insert” CREATES a collection if needed
  • Importing data…using MongoVue
  • Viewing Collection Data
  • DemoUSING VELOCITY FOR MODELING
  • Modeling Use GridFS for BLOBs Keep collections smallUse short names • Can create non- default (narrower) key• each name is saved for • Document size each document maximum is 4 MB• can save up to 30% storage
  • Comparing…
  • DemoQUERY MONGODB DATA
  • Using FindFind, Fields, Sort, Count, Skip, Limit, Visualize or Export
  • Data Visualization
  • Queries
  • Queries 2 …
  • Queries 3…
  • What is Grouping?• Similar to T-SQL ‘Group By’• Written in javascript
  • What about Joins? Can use Arrays No Can De-normalize traditional Can use Embedded schema joins in Documents MongoDB Can use DBRef
  • About the Aggregation Framework• New in MongoDB 2.2• Layer on top to facilitate easier query-writing
  • Query Tuning• Use best indexes – Evaluate use of _id – Add columns to index (specificity) – Multiple columns, most specific first – Can use fully covered indexing (indexOnly:true) – Test to make sure indexes are being used• Qty scanned s/b same as QTY returned• Use .explain
  • Understanding Explain• Query execution detail plan• Review number of scanned objects
  • Understanding moreADD INDEXES TO MONGODB
  • Modifying DataUpdate Update w/ $set Update w/ $inc• alone does a replace • does an update • increments Upserts Multiple field • must be enabled updates • then insert if • occur by default new, update if existing
  • Using Update
  • Understanding more…USING GRIDFS
  • What is GridFS?• Used to hold objects larger than 16 MB
  • DemoCONNECTING TO MONGODB WITH C#
  • Programming against MongoDB
  • More Information• MongoDB – http://www.mongodb.org• 10gen – http://www.10gen.com/contact – info@10gen.com• YouTube videos (from Lynn Langit) – MongoDB Playlist - https://www.youtube.com/playlist?list=PLCE5902FB1D284880 &feature=view_all• MongoDB LA UG - http://www.meetup.com/Los-Angeles- MongoDB-User-Group
