}

A query for entities.

This type is not used in any activity, and only used as part of another schema.

Fields

start_cursor: Option<String>

A starting point for the query results. Query cursors are returned in query result batches and can only be used to continue the same query.

kind: Option<Vec<KindExpression>>

The kinds to query (if empty, returns entities of all kinds). Currently at most 1 kind may be specified.

projection: Option<Vec<Projection>>

The projection to return. Defaults to returning all properties.

distinct_on: Option<Vec<PropertyReference>>

The properties to make distinct. The query results will contain the first result for each distinct combination of values for the given properties (if empty, all results are returned).

filter: Option<Filter>

The filter to apply.

limit: Option<i32>

The maximum number of results to return. Applies after all other constraints. Optional. Unspecified is interpreted as no limit. Must be >= 0 if specified.

offset: Option<i32>

The number of results to skip. Applies before limit, but after all other constraints. Optional. Must be >= 0 if specified.

end_cursor: Option<String>

An ending point for the query results. Query cursors are returned in query result batches and can only be used to limit the same query.

order: Option<Vec<PropertyOrder>>

The order to apply to the query results (if empty, order is unspecified).
