Use GetShardIterator with an AWS SDK or CLI

The following code examples show how to use GetShardIterator.

Action examples are code excerpts from larger programs and must be run in context. You can see this action in context in the following code example:

To obtain a shard iterator

The following get-shard-iterator example uses the AT_SEQUENCE_NUMBER shard iterator type and generates a shard iterator to start reading data records exactly from the position denoted by the specified sequence number.

aws kinesis get-shard-iterator \
    --stream-name samplestream \
    --shard-id shardId-000000000001 \
    --shard-iterator-type LATEST

Output:

{
    "ShardIterator": "AAAAAAAAAAFEvJjIYI+3jw/4aqgH9FifJ+n48XWTh/IFIsbILP6o5eDueD39NXNBfpZ10WL5K6ADXk8w+5H+Qhd9cFA9k268CPXCz/kebq1TGYI7Vy+lUkA9BuN3xvATxMBGxRY3zYK05gqgvaIRn94O8SqeEqwhigwZxNWxID3Ej7YYYcxQi8Q/fIrCjGAy/n2r5Z9G864YpWDfN9upNNQAR/iiOWKs"
}

Example 1: Returns a shard iterator for the specified shard and starting position. Details of the shard identifiers and sequence numbers can be obtained from the output of the Get-KINStream cmdlet, by referencing the Shards collection of the returned stream object. The returned iterator can be used with the Get-KINRecord cmdlet to pull data records in the shard.

Get-KINShardIterator -StreamName "mystream" -ShardId "shardId-000000000000" -ShardIteratorType AT_SEQUENCE_NUMBER -StartingSequenceNumber "495598645..."

Output:
