Expand description
A task that manages rehydration.
Fields§
§build_info: &'static BuildInfo
The build information for this process.
command_rx: UnboundedReceiver<RehydrationCommand<T>>
A channel upon which commands intended for the storage replica are delivered.
response_tx: UnboundedSender<StorageResponse<T>>
A channel upon which responses from the storage replica are delivered.
sources: BTreeMap<GlobalId, RunIngestionCommand>
The sources that have been observed.
sinks: BTreeMap<GlobalId, CreateSinkCommand<T>>
The exports that have been observed.
uppers: BTreeMap<GlobalId, Antichain<T>>
The upper frontier information received.
sinces: BTreeMap<GlobalId, Antichain<T>>
The since frontiers that have been observed.
initialized: bool
Set to true
once StorageCommand::InitializationComplete
has been
observed.
current_epoch: ClusterStartupEpoch
The current epoch for the replica we are connecting to.
config: StorageParameters
Storage configuration that has been observed.
metrics: RehydratingStorageClientMetrics
Prometheus metrics
grpc_client_params: GrpcClientParameters
gRPC client parameters.
variable_length_row_encoding: bool
Whether to enable variable-length row encoding.
