Crossfilter is a JavaScript library for fast n-dimensional filtering and grouping of large multivariate datasets in the browser, using sorted indexes and incremental filtering to achieve sub-30ms interactions on millions of records. This original Square repository is no longer actively developed; an actively maintained fork lives under the Crossfilter Organization.

Use cases

• filter and group a million-record dataset in the browser with sub-30ms interactions
• power live histograms and top-K lists for dashboard views
• build coordinated chart views that update together when a filter changes
• slice and dice payment or transaction history for analytics
• incrementally adjust filter values without recomputing from scratch

When to choose

• you need fast multidimensional filtering and grouping of large datasets client-side
• you are building coordinated dashboards, especially with DC.js
• you want incremental filtering backed by sorted indexes rather than full recomputation

When to avoid

• you need active development, new features, or official support - use the maintained crossfilter/crossfilter fork instead
• your data lives server-side and filtering can be done in a database
• you need a full charting library rather than a filtering/grouping engine
