Dynamodb scan map. When making a Scan, a request can say how many Segments to divide the table into and which Segment number is claimed by the particular request. This allows you to spin up multiple threads or processes to scan the data in parallel. . Scan operations proceed sequentially; however, for faster performance on a large table or secondary index, applications can request a parallel Scan operation by providing the Segment and TotalSegments parameters. To alleviate this, DynamoDB has the notion of Segments which allow for parallel scans. Find expert tips and code snippets. For more information, see Parallel Scan in the Amazon DynamoDB Developer Guide . An alternate solution would be for you to index your data in AWS Elasticsearch service as well as DynamoDB.
