Amazon Kinesis
This guide shows you how to ingest a stream of records from an Amazon Kinesis topic into a Pinot table.
To ingest events from an Amazon Kinesis stream into Pinot, set the following configs into the table config:
where the Kinesis specific properties are:
Property | Description |
---|---|
streamType | This should be set to "kinesis" |
stream.kinesis.topic.name | Kinesis stream name |
region | Kinesis region e.g. us-west-1 |
accessKey | Kinesis access key |
secretKey | Kinesis secret key |
shardIteratorType | Set to LATEST to consume only new records, TRIM_HORIZON for earliest sequence number_,_ AT___SEQUENCE_NUMBER and AFTER_SEQUENCE_NUMBER to start consumptions from a particular sequence number |
maxRecordsToFetch | ... Default is 20. |
Kinesis supports authentication using the DefaultCredentialsProviderChain. The credential provider looks for the credentials in the following order -
Environment Variables -
AWS_ACCESS_KEY_ID
andAWS_SECRET_ACCESS_KEY
(RECOMMENDED since they are recognized by all the AWS SDKs and CLI except for .NET), orAWS_ACCESS_KEY
andAWS_SECRET_KEY
(only recognized by Java SDK)Java System Properties -
aws.accessKeyId
andaws.secretKey
Web Identity Token credentials from the environment or container
Credential profiles file at the default location
(~/.aws/credentials)
shared by all AWS SDKs and the AWS CLICredentials delivered through the Amazon EC2 container service if
AWS_CONTAINER_CREDENTIALS_RELATIVE_URI
environment variable is set and security manager has permission to access the variable,Instance profile credentials delivered through the Amazon EC2 metadata service
Although you can also specify the accessKey
and secretKey
in the properties above, we don't recommend this unsecure method. We recommend using it only for non-production proof-of-concept (POC) setups. You can also specify other AWS fields such as AWS_SESSION_TOKEN as environment variables and config and it will work.
Limitations
ShardID
is of the format "shardId-000000000001". We use the numeric part aspartitionId
. OurpartitionId
variable is integer. If shardIds grow beyondInteger.MAX\_VALUE
, we will overflow into the partitionId space.Segment size based thresholds for segment completion will not work. It assumes that partition "0" always exists. However, once the shard 0 is split/merged, we will no longer have partition 0.
