public RecordsPublisher createRecordsFetcher(GetRecordsRetrievalStrategy getRecordsRetrievalStrategy,
                                             String shardId,
                                             MetricsFactory metricsFactory,
                                             int maxRecords)

Description copied from interface: RecordsFetcherFactory

Returns a RecordsPublisher to be used for retrieving records for a given shard.

Specified by:

createRecordsFetcher in interface RecordsFetcherFactory

Parameters:

getRecordsRetrievalStrategy - GetRecordsRetrievalStrategy to be used with the RecordsPublisher

shardId - ShardId of the shard that the fetcher will retrieve records for

metricsFactory - MetricsFactory used to create metricScope

maxRecords - Max number of records to be returned in a single get call

Returns:

RecordsPublisher used to get records from Kinesis.

maxPendingProcessRecordsInput

public void maxPendingProcessRecordsInput(int maxPendingProcessRecordsInput)

Description copied from interface: RecordsFetcherFactory

Sets the maximum number of ProcessRecordsInput objects the RecordsPublisher can hold, before further requests are blocked.

Specified by:

maxPendingProcessRecordsInput in interface RecordsFetcherFactory

Parameters:

maxPendingProcessRecordsInput - The maximum number of ProcessRecordsInput objects that the cache will accept before blocking.

maxByteSize

public void maxByteSize(int maxByteSize)

Description copied from interface: RecordsFetcherFactory

Sets the max byte size for the RecordsPublisher, before further requests are blocked. The byte size of the cache is the sum of byte size of all the ProcessRecordsInput objects in the cache at any point of time.

Specified by:

maxByteSize in interface RecordsFetcherFactory

Parameters:

maxByteSize - The maximum byte size for the cache before blocking.

maxRecordsCount

public void maxRecordsCount(int maxRecordsCount)

Description copied from interface: RecordsFetcherFactory

Sets the max number of records for the RecordsPublisher can hold, before further requests are blocked. The records count is the sum of all records present in across all the ProcessRecordsInput objects in the cache at any point of time.

Specified by:

maxRecordsCount in interface RecordsFetcherFactory

Parameters:

maxRecordsCount - The mximum number of records in the cache before blocking.

dataFetchingStrategy

public void dataFetchingStrategy(DataFetchingStrategy dataFetchingStrategy)

Description copied from interface: RecordsFetcherFactory

Sets the dataFetchingStrategy to determine the type of RecordsPublisher to be used.

Specified by:

dataFetchingStrategy in interface RecordsFetcherFactory

Parameters:

dataFetchingStrategy - Fetching strategy to be used

idleMillisBetweenCalls

public void idleMillisBetweenCalls(long idleMillisBetweenCalls)

Description copied from interface: RecordsFetcherFactory

Sets the maximum idle time between two get calls.

Specified by:

idleMillisBetweenCalls in interface RecordsFetcherFactory

Parameters:

idleMillisBetweenCalls - Sleep millis between calls.
