Overview
Kinesis Streams is aimed at users who want to build custom applications to process or analyze streaming data.
AWS CLI Operations
Prerequisites
Set up the AWS credentials and region first.
List Streams
aws kinesis list-streams
Get Details about a Specific Stream
Returns informations about a shard, including the ID of its shards.
aws kinesis describe-stream --stream-name <stream-name>
Output sample:
{
"StreamDescription": {
"KeyId": null,
"EncryptionType": "NONE",
"StreamStatus": "ACTIVE",
"StreamName": "bizEventIn",
"Shards": [
{
"ShardId": "shardId-000000000000",
"HashKeyRange": {
"EndingHashKey": "340282366920938463463374607431768211455",
"StartingHashKey": "0"
},
"SequenceNumberRange": {
"StartingSequenceNumber": "49589495463753313109232148314676658043283830396753543170"

Create a Stream
aws kinesis create-stream --stream-name <stream-name> --shard-count 1
Put a Record
aws kinesis put-record --stream-name <stream-name> --partition-key 1 --data testdata
Create a Stream
Get a Record
First then get a shard iterator and then get the record:
SHARD_ITERATOR=$(aws kinesis get-shard-iterator --shard-id shardId-000000000000 --shard-iterator-type TRIM_HORIZON --stream-name bizEventIn --query 'ShardIterator') aws kinesis get-records --shard-iterator $SHARD_ITERATOR
This command will return all the records present in the stream from the position specified by the shard iterator, and a new shard iterator (NextShardIterator) that should be used to read the records arrived after this command was run.
Delete a Stream
aws kinesis delete-stream --stream-name <stream-name>
