public sealed class CommandPartition : IEquatable<CommandPartition>
Reference documentation and code samples for the Google.Cloud.Spanner.Data class CommandPartition.
Represents a partition of data upon which a SpannerCommand will execute.
Partitions are useful for parallelizing large operations across several tasks or processes.
After partitioning a query, the partitions can be serialized using this method, then deserialized
with FromBase64String(string) on multiple machines, allowing parallel processing.
