public sealed class PartitionId : IMessage<PartitionId>, IEquatable<PartitionId>, IDeepCloneable<PartitionId>, IBufferMessage, IMessage
A partition ID identifies a grouping of entities. The grouping is always
by project and namespace, however the namespace ID may be empty.
A partition ID contains several dimensions:
project ID and namespace ID.
Partition dimensions:
May be "".
Must be valid UTF-8 bytes.
Must have values that match regex [A-Za-z\d\.\-_]{1,100}
If the value of any dimension matches regex __.*__, the partition is
reserved/read-only.
A reserved/read-only partition ID is forbidden in certain documented
contexts.
Foreign partition IDs (in which the project ID does
not match the context project ID ) are discouraged.
Reads and writes of foreign partition IDs may fail if the project is not in an active state.
