{cluster}: the name of the CDF cluster, e.g.,westeurope-1.{apiVersion}: the version of the OData service API (latest isv1).{project}: the name of the CDF project, e.g.,publicdata.
Filtering asset-centric resource types
The asset-centric OData service can push filters down to CDF. This improves performance by ensuring that filtering happens on the server side, reducing the amount of data transmitted to the client.Filtering options
- Pushdown: Filter functions that are pushed down to the CDF backend. This is the most efficient filtering.
- Local: Filtering done by the OData service before returning the result to the client. Less efficient than pushdown.
- Client-side: Filtering done by the client after data is retrieved. Least efficient.
Definitions
- FilterFunctions:
Contains,StartsWith, andEndsWith. - Comparison:
<,<=,>,>=, and=. - Search: uses the search API and may require additional local filtering.
Search returns a limited number of rows, and you may not receive all matching data in CDF.
