Package Exports
- vega-dataflow
- vega-dataflow/src/ChangeSet
- vega-dataflow/src/Tuple
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (vega-dataflow) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
vega-dataflow
Reactive dataflow processing.
Defines a reactive dataflow graph that can process both scalar values and
streaming relational data. A central Dataflow instance manages and
schedules a collection of Operator instances, each of which is a node in
a dataflow graph. Each operator maintains a local state value, and may
also process streaming data objects (or tuples) passing through. Operators
may depend on a set of named Parameters, which can either be fixed values
or live references to other operator values.
Upon modifications to operator parameters or input data, changes are
propagated through the graph in topological order. Pulse objects propagate
from operators to their dependencies, and carry queues of added, removed
and/or modified tuples.
This module contains a library of Operator types for data stream query
processing, including data generation, sampling, filtering, binning,
group-by aggregation, and cross-stream lookup operations.
For more information about data stream transforms, see the Vega transform documentation.
