MongoDB 2.6 is great but what about 2.8? SA |
Eng, MongoDB Norberto #lxmug
What’s New • Query System Improvements • Integrated Text Search
• Enterprise-Grade Security • Non-Stop Operations
Query System Improvements
Query System Improvments • Index Intersection • Pipelined Data Transformations
• New Update Operators • New Set Operators
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
Pipelined Data Transformations • $out for Aggregation • Write results
sets to a named collection • No limit on output size • Cursors back for results
New Update Operators • $mul • $min • $max •
$currentDate • New modifiers for $push
New Set Operators • $project operator in the aggregation pipeline
now supports an expanded set of expressions – $setIsSubset – $setEquals – $setDifference – $setIntersection – $setUnion – $allElementsTrue – $anyElementTrue
Redaction • Field-level Security • Access policies can be set
in Query Language • Two criteria to set Permissions – Document Content – User Privilege
Integrated Search
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)
Possibilities with Text Search • Relevance ranking • Boolean operators
• Language-specific tokenization and stemming • Fielded search • Field-weighted scoring • Stop words • Type-aware indexes
Security
None
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 MongoDB Enterprise-Grade Security *Requires MongoDB Enterprise
Security • Authentication with LDAP (Enterprise only) • x.509 Certificates
• User defined roles • Auditing (Enterprise only) • Windows Kerberos Support (And Windows Enterprise)
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
Operational Improvements
Improving Performance and Scalability • Query Router Connection Pooling •
Bulk Write Operations • Resource Overload Protection with $maxTimeMS
Operational Improvements • Background Secondary Indexing • Mixed SSL Connections
• Expanded SNMP Support
So … what’s coming?!
Document Level Locking!!!
