Deletion from amazon dynamodb

Question

Is there any efficient way to delete all the items from a amazon dynamodb tabe at once.I have gone through the aws docs but there it's shown deletion of a single item.

Answer 1

Do the following steps:

1. Make delete table request
2. In the response you will get the TableDescription
3. Using TableDescription create the table again.

For step 1 and 2 click here

for step 3 click here

That's what I do in my application.

Answer 2

DynamoDBMapper will do the job in few lines :

AWSCredentials credentials = new PropertiesCredentials(credentialFile);
client = new AmazonDynamoDBClient(credentials);
DynamoDBMapper mapper = new DynamoDBMapper(this.client);
DynamoDBScanExpression scanExpression = new DynamoDBScanExpression();
PaginatedScanList<LogData> result = mapper.scan(LogData.class,  scanExpression);
for (LogData data : result) {
    mapper.delete(data);
}
