Interface DynamoDBMapperConfig.BatchLoadRetryStrategy

All Known Implementing Classes:

DynamoDBMapperConfig.DefaultBatchLoadRetryStrategy, DynamoDBMapperConfig.NoRetryBatchLoadRetryStrategy

Enclosing class:

DynamoDBMapperConfig

public static interface DynamoDBMapperConfig.BatchLoadRetryStrategy

DynamoDBMapper.batchLoad(Iterable, DynamoDBMapperConfig) breaks the requested items in batches of maximum size 100. When calling the Dynamo Db client, there is a chance that due to throttling, some unprocessed keys will be returned. This interfaces controls whether we need to retry these unprocessed keys and it also controls the strategy as to how retries should be handled

Method Summary

Modifier and Type	Method and Description
long	getDelayBeforeNextRetry(BatchLoadContext batchLoadContext) Returns delay(in milliseconds) before retrying Unprocessed keys
boolean	shouldRetry(BatchLoadContext batchLoadContext) Checks if the batch load request should be retried.
