Class BinaryLogFileManager

java.lang.Object

com.illumon.iris.logfilemanager.BinaryLogFileManager

Direct Known Subclasses:

DateBinaryLogFileManager, StandardBinaryLogFileManager

public abstract class BinaryLogFileManager
extends Object

Abstract class providing base logic and required methods to be implemented for classes which determine column partition information for binary log files. Any implementation must include a constructor which takes the same parameters as BinaryLogFileManager(Logger, DataRoutingService, LogtailerConfiguration.ConfigurationEntry, LogtailerMain.LogtailerRunDetails, LogtailerDestinationThrottles). That constructor should call this constructor with super(...).

findAndSetMatchingFiles

protected File[] findAndSetMatchingFiles(BinaryLogFileManager.TableLocationIdentifierStatus tableLocationIdentifierStatus)

Regenerate and return the matching-files-array for the specified TableLocationIdentifierStatus

Parameters:

tableLocationIdentifierStatus - the tableLocationIdentifierStatus for the event that triggered this call

Returns:

the current array of matching files for this TableLocationIdentifierStatus

getTableLocationIdentifierStatusMap

@VisibleForTesting
public Map<TableLocationIdentifier,BinaryLogFileManager.TableLocationIdentifierStatus> getTableLocationIdentifierStatusMap()

This is for testing only.

Returns:

the TableLocationIdentifier status map

handleFile

public boolean handleFile(Path newFilePath,
 boolean isStartup)

Given a new file, see if it belongs to this BinaryLogFileManager, and if so, handle it. This determination is based on the parsed TableLocationIdentifier for the file.

Parameters:

newFilePath - the new file's full Path

isStartup - if true, this is a file found during startup

Returns:

true if the file was consumed by this BinaryLogFileManager

requestShutdown

public void requestShutdown()

Prevent any new destination threads from being created, and request shutdown on all the existing threads.
