Crossfilter
Fast n-dimensional filtering and grouping of records.
Features
- Crossfiltering Calculation Engines - Provides a browser-based engine for sub-30ms crossfiltering calculations with incremental aggregation.
- Crossfiltering - Provides a library for coordinated crossfiltering across multiple dataset dimensions for interactive exploration.
- Coordinated Multivariate Explorers - Explores large multivariate datasets with coordinated filtering across dimensions and real-time visualization updates.
- Aggregate Group Trees - Organizes groups into a tree for drill-down and roll-up aggregation without recomputation.
- Incremental - Provides a library for incremental aggregation updates as filter values change, avoiding full recomputation.
- Coordinated Multivariate Filters - Applies coordinated filters across multiple dimensions for interactive exploration of millions of records.
- Incremental Group-By Recalculations - Updates aggregate groups incrementally by tracking record filter changes, avoiding full dataset scans.
- Incremental Histogram Aggregations - Computes histograms and top-K lists incrementally as filter conditions change, avoiding full recomputation.
- Multidimensional Filter Combinations - Applies and combines filters on multiple data dimensions simultaneously to isolate record subsets.
- Dimension-Indexed Bitmap Filters - Provides bitmap-based dimension filtering for fast intersection and union across multiple data dimensions.
- Incremental Aggregation Recalculations - Recalculates histograms and top-K lists incrementally as filter values change for fast, fluid updates.
- Deferred Group Evaluations - Defers group computation until query time, batching filter changes for efficient recalculation.
- In-Memory Multivariate Filters - Provides an in-memory library for fast filtering and grouping of multivariate datasets with incremental aggregation.
- Dimension Filter Propagation - Implements event-driven propagation of filter changes across dimensions for efficient incremental updates.
- Crossfiltering View Coordinations - Coordinates multiple linked views so filtering in one automatically updates all others.
- Interactive Analytics Engines - Analyzes millions of records interactively with sub-30-millisecond response times.
- Integer Record Pointers - Links records across dimensions using integer pointers for reduced memory overhead and improved cache locality.
- Group Key Sorted Arrays - Stores group keys in sorted arrays for efficient binary-search lookups and range queries during aggregation.
