MongoDB 2.6 is great but what about 2.8?
1 like669 views
The document summarizes the new features in MongoDB 2.8, including improved query systems with new operators, integrated text search, enhanced security features, and improved operational capabilities. Key updates involve index intersection for optimized queries, pipelined data transformations, new update operators, expanded set operators, field-level security and access policies, text search integration, authentication with LDAP and certificates, user-defined roles, auditing, and performance/scalability improvements like connection pooling and resource protection. Future releases may include document-level locking, pluggable storage engines, expanded monitoring, backup, and automation APIs.
MongoDB 2.6 is great but what about 2.8?
- 1. #lxmug MongoDB 2.6 is great but what about 2.8? Norberto SA | Eng, MongoDB
- 2. What’s New • Query System Improvements • Integrated Text Search • Enterprise-Grade Security • Non-Stop Operations
- 4. Query System Improvments • Index Intersection • Pipelined Data Transformations • New Update Operators • New Set Operators
- 5. Index Intersection • Simpler ad-hoc queries • Existing Indexes can be combined to optimize a query – Less Index Maintenance – Smaller Working Set – Lower Write Overhead – More Adaptive
- 6. Pipelined Data Transformations • $out for Aggregation • Write results sets to a named collection • No limit on output size • Cursors back for results
- 7. New Update Operators • $mul • $min • $max • $currentDate • New modifiers for $push
- 8. New Set Operators • $project operator in the aggregation pipeline now supports an expanded set of expressions – $setIsSubset – $setEquals – $setDifference – $setIntersection – $setUnion – $allElementsTrue – $anyElementTrue
- 9. Redaction • Field-level Security • Access policies can be set in Query Language • Two criteria to set Permissions – Document Content – User Privilege
- 11. Text Search • Now production-ready • Integrated with MongoDB’s Query Engine • Multi-language document support • Text-search expressions can be used in the Aggregation Framework (not true in 2.5.4)
- 12. Possibilities with Text Search • Relevance ranking • Boolean operators • Language-specific tokenization and stemming • Fielded search • Field-weighted scoring • Stop words • Type-aware indexes
- 13. Security
- 15. MongoDB Enterprise-Grade Security Business Needs Replica Set Benefits Authentication In Database LDAP* Kerberos* x.509 Certificates* Authorization Built-in Roles User-Defined Roles Field Level Security Auditing Admin Operations* Queries (via Partner Solutions) Encryption Network: SSL (with FIPS 140-2)* Disk: Partner Solutions *Requires MongoDB Enterprise
- 16. Security • Authentication with LDAP (Enterprise only) • x.509 Certificates • User defined roles • Auditing (Enterprise only) • Windows Kerberos Support (And Windows Enterprise)
- 17. State of Security in MongoDB • Authentication – Who are you? – X.509 authentication and Kerberos • Authorization – What can you do? – User Defined Roles, Collection-level Access Control • Auditing – What have you done? – DDL, User Manipulation, Authorization failure
- 19. Improving Performance and Scalability • Query Router Connection Pooling • Bulk Write Operations • Resource Overload Protection with $maxTimeMS
- 20. Operational Improvements • Background Secondary Indexing • Mixed SSL Connections • Expanded SNMP Support
- 21. So … what’s coming?!
- 23. Pluggable Storage Engine API
- 25. MMS Backup API
