createTransient method
Creates a transient projection.
This projection runs until the end of the log and
then continues running. Transient projections are not persisted
by the server and will be lost if the projection subsystem is
restarted. The name
parameter is used as an identifier for operations on
the created projection. The id of the resulting stream is
by default \$projections-${name}-result
if resultStreamName
is not given with the options method in the query,
options({
resultStreamName: "my_demo_projection_result",
$includeLinks: false,
reorderEvents: false,
processingLag: 0
})
```. The [query] parameter contains
the JavaScript you want created as a one time projection.
Continuous projections have explicit names and you can enable or
disable them via this name. See [user-defined projections API](https://developers.eventstore.com/server/v20.10/docs/projections/user-defined-projections.html#user-defined-projections-api).
for more information about the query language (javascript).
Implementation
Future<void> createTransient(
String name,
String query, {
UserCredentials? userCredentials,
}) async {
return $runRequest(() async {
final client = await $getClient();
final options = (CreateReq_Options()
..transient = (CreateReq_Options_Transient()..name = name)
..query = query);
await client.create(
CreateReq()..options = options,
options: $getOptions(
userCredentials: userCredentials,
),
);
});
}
