NewProtectedTimestampStateReader returns an instance of a ProtectedTimestampStateReader that can be used to fetch target specific protected timestamp records given the supplied ptpb.State.

RecordsToEntries converts a list of records to a list roachpb.SpanConfigEntry protos suitable for sending over the wire.

TargetsFromProtos converts a list of roachpb.SpanConfigTargets (received over the wire) to a list of Targets.

TargetsFromRecords extracts the list of underlying targets from the given list of Records.

TargetsToProtos converts a list of targets to a list of roachpb.SpanConfigTarget protos suitable for sending over the wire.

TestingEntireSpanConfigurationStateTargets returns a list of targets which can be used to read the entire span configuration state.

TestingMakeTenantKeyspaceTargetOrFatal is like MakeTenantKeyspaceTarget except it fatals on error.

SystemTargetTypeAllTenantKeyspaceTargetsSet represents a system target that encompasses all system targets that have been set by the source tenant over specific tenant's keyspace.

SystemTargetTypeEntireKeyspace indicates that the system target is targeting the entire keyspace.

SystemTargetTypeSpecificTenantKeyspace indicates that the system target is targeting a specific tenant's keyspace.

DescriptorUpdate captures the ID and the type of descriptor or zone that been updated.

ProtectedTimestampStateReader provides a target specific view of the protected timestamp records stored in the system table.

ProtectedTimestampUpdate captures a protected timestamp record with a cluster or tenant target that been updated.

Record ties a target to its corresponding config.

SQLUpdate captures either a descriptor or a protected timestamp update.

SystemTarget specifies the target of a system span configuration.
