In the case of the scan, data is only filtered after it is returned. It is typically much faster than a scan.Ī scan is performed when anything other than a partition key or a sort key is used to filter the data. This is done by the use of partition keys and sort keys that are defined on the table to perform the filter. In DynamoDB, a query is used when some of the data can be filtered before results are returned.

The CData JDBC Driver for DynamoDB 2018 automatically attempts to figure out which type to use, based on the WHERE clause of the SQL statement. These operations vary in execution times. Querying the DynamoDB DataĭynamoDB has two distinct operations to read data from tables: query and scan.

This page describes how to query the DynamoDB data, how to download the DynamoDB driver and deploy it, how to connect to DynamoDB with a connection string, provides information about the DynamoDB data model, and more.įor the list of supported connectors, see Introduction to Data Sources. Once you have connected to DynamoDB, you can import a variety of tables from the DynamoDB API. To obtain a connection string, you will need to create a DynamoDB developers account.
The connection string is used to authenticate users who connect to the DynamoDB APIs. For advanced inquiries specific to driver functionality, you can also contact the certification partner’s support directly via you have downloaded the driver, you can connect through a connection string in Sisense. For any support issues or additional functionality requests, contact your Sisense representative or open a request through the Sisense Help Center. The support for the connector is provided by Sisense and will be assisted by the certification partner's support, if needed.
The DynamoDB connector offers the most natural way to connect Java applications with the DynamoDB real-time NoSQL cloud database service. The Sisense DynamoDB connector is a certified connector that allows you to import data from the DynamoDB API into Sisense via theSisense generic JDBC connector.
