Class Shard

Namespace

DynaSharp.Streams

Assembly

DynaSharp.dll

A shard of a stream: a sequence of records that is read in order.

public sealed record Shard : IEquatable<Shard>

Inheritance

object

Shard

Implements

IEquatable<Shard>

Inherited Members

object.GetType()

object.Equals(object, object)

object.ReferenceEquals(object, object)

Remarks

Shards form a tree. When a shard fills up or DynamoDB repartitions the table, it is closed and its children take over; the children name it in ParentShardId. To read all changes of an item in order, finish the parent before its children. A shard is open while EndingSequenceNumber is null.

DynamoDB removes a shard 24 hours after it was closed. The list of shards can change between two calls of DescribeStream.

ShardId

Gets the identifier of the shard. DynamoDB sends it with every shard: null only if the response omits it.

public string? ShardId { get; init; }

Property Value
