Description

Conditional class for inserting or updating a row.

When inserting or deleting a row (in a non-batch operation), you can specify one or more conditions that must be met in order to perform the action. The conditions are: the server already contains a specific value for a specific column, or the column does not exist.

TAmazonRowConditional can be used to insure that multiple processes do not overwrite each other.
