The following are some AWS Command Line Interface (AWS CLI) examples of using condition expressions. These examples are based on the ProductCatalog table, which was introduced in Referring to item attributes when using expressions in DynamoDB. The partition key for this table is Id; there is no...
The primary key that uniquely identifies each item in an Amazon DynamoDB table can be simple (a partition key only) or composite (a partition key combined with a sort key). You should design your application for uniform activity across all partition keys in the table and its secondary index...
the partition key must be something that is easily queried by your application with a simple lookup. An example is usingkey=value, which returns either a unique item or fewer items. There is a 1-MB limit on items that you can fetch through a...
Map.Entry<String, AttributeValue> partitionKey = ... Map.Entry<String, AttributeValue> sortKey = ... GetItemRequest request = new GetItemRequest().withTableName(tableName) .withKey(partitionKey, sortKey); GetItemResult result = dynamoDBClient.getItem(request); Map<String, AttributeValue> item...
You need to know the partition keys in order to insert the new items. Scan the whole table If your table schema has only a partition key (no sort key), then generating a distinct list of partition keys can be done fairly efficiently using a table scan. Each it...

Hi, The update_item method on the resource("dynamodb").Table("table_name") object should raise ValidationException if the user tries to change the partition key. Specifically it should raise: botocore.exceptions.ClientError: An error occ...
Describe the problem you faced When using org.apache.hudi.aws.transaction.lock.DynamoDBBasedLockProvider as a lock provider for Hudi, the documentation suggests that hoodie.write.lock.dynamodb.partition_key will by default be set to the ...
However, this won't work. It's thecombinationof a partition key and sort key that makes an item unique within the table. Using this key structure, you're confirming that an email address will only be used oncefor that username. Now you've lost the original uniqueness properties on the ...
