createRecordsFetcher

public GetRecordsCache createRecordsFetcher(GetRecordsRetrievalStrategy getRecordsRetrievalStrategy,
                                            String shardId,
                                            IMetricsFactory metricsFactory,
                                            int maxRecords)

Description copied from interface: RecordsFetcherFactory

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

Specified by:

createRecordsFetcher in interface RecordsFetcherFactory

Parameters:

getRecordsRetrievalStrategy - GetRecordsRetrievalStrategy to be used with the GetRecordsCache

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:

GetRecordsCache used to get records from Kinesis.

setMaxPendingProcessRecordsInput

public void setMaxPendingProcessRecordsInput(int maxPendingProcessRecordsInput)

Description copied from interface: RecordsFetcherFactory

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

Specified by:

setMaxPendingProcessRecordsInput in interface RecordsFetcherFactory

Parameters:

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

setMaxByteSize

public void setMaxByteSize(int maxByteSize)

Description copied from interface: RecordsFetcherFactory

Sets the max byte size for the GetRecordsCache, 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:

setMaxByteSize in interface RecordsFetcherFactory

Parameters:

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

setMaxRecordsCount

public void setMaxRecordsCount(int maxRecordsCount)

Description copied from interface: RecordsFetcherFactory

Sets the max number of records for the GetRecordsCache 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:

setMaxRecordsCount in interface RecordsFetcherFactory

Parameters:

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

setDataFetchingStrategy

public void setDataFetchingStrategy(DataFetchingStrategy dataFetchingStrategy)

Description copied from interface: RecordsFetcherFactory

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

Specified by:

setDataFetchingStrategy in interface RecordsFetcherFactory

Parameters:

dataFetchingStrategy - Fetching strategy to be used

setIdleMillisBetweenCalls

public void setIdleMillisBetweenCalls(long idleMillisBetweenCalls)

Description copied from interface: RecordsFetcherFactory

Sets the maximum idle time between two get calls.

Specified by:

setIdleMillisBetweenCalls in interface RecordsFetcherFactory

Parameters:

idleMillisBetweenCalls - Sleep millis between calls.
