Amazon DynamoDB Scan

KNIME Amazon DynamoDB Nodes version 4.3.0.v202011231544 by KNIME AG, Zurich, Switzerland

This node performs a scan over a DynamoDB table, returning a KNIME table with all the items not filtered out by the filter expression. Important: the columns and their types of the KNIME output table are determined from the first batch of items retrieved from DynamoDB. One batch has a maximum size of 1MB. If an item in a later batch, i.e. after loading 1MB, has an attribute that did not occur before, this attribute is not written to the output table.

Table Name
The table to access.
Custom Endpoint (*)
A custom endpoint if the default AWS endpoint should not be used, e.g. for DynamoDB Local.
Index name (*)
The name of the index to use or empty if no index should be scanned.
Consistent Read
Whether consistent read should be enforced (costs twice the throughput capacity units).
The maximum number of items to retrieve.
Publish consumed capacity units as flow variable
If checked, the total capacity units used by the operation are published as a flow variable named "queryConsumedCapacity".
