}Expand description
CreateStreamingJobContext carries one-time infos for creating a streaming job.
Note: for better readability, keep this struct complete and immutable once created.
Fields§
§dispatchers: HashMap<ActorId, Vec<Dispatcher>>New dispatchers to add from upstream actors to downstream actors.
upstream_root_actors: HashMap<TableId, Vec<ActorId>>Upstream root fragments’ actor ids grouped by table id.
Refer to the doc on MetadataManager::get_upstream_root_fragments for the meaning of “root”.
internal_tables: BTreeMap<u32, Table>Internal tables in the streaming job.
building_locations: LocationsThe locations of the actors to build in the streaming job.
existing_locations: LocationsThe locations of the existing actors, essentially the upstream mview actors to update.
definition: StringDDL definition.
mv_table_id: Option<u32>§create_type: CreateType§ddl_type: DdlType§replace_table_job_info: Option<(StreamingJob, ReplaceTableContext, StreamJobFragments)>Context provided for potential replace table, typically used when sinking into a table.
snapshot_backfill_info: Option<SnapshotBackfillInfo>§option: CreateStreamingJobOption§streaming_job: StreamingJobImplementations§
