public class RedisRecordHandler
extends RecordHandler

Handles data read record requests for the Athena Redis Connector.

For more detail, please see the module's README.md, some notable characteristics of this class include:

1. Supporting literal, zset, and hash value types. 2. Attempts to resolve sensitive configuration fields such as redis-endpoint via SecretsManager so that you can substitute variables with values from by doing something like hostname:port:password=${my_secret}

Description copied from class: RecordHandler

A more stream lined option for reading the row data associated with the provided Split. This method differs from doReadRecords(...) in that the SDK handles more of the request lifecycle, leaving you to focus more closely on the task of actually reading from your source.

Specified by:

readWithConstraint in class RecordHandler

Parameters:

spiller - A BlockSpiller that should be used to write the row data associated with this Split. The BlockSpiller automatically handles chunking the response, encrypting, and spilling to S3.

recordsRequest - Details of the read request, including: 1. The Split 2. The Catalog, Database, and Table the read request is for. 3. The filtering predicate (if any) 4. The columns required for projection.

queryStatusChecker - A QueryStatusChecker that you can use to stop doing work for a query that has already terminated
