Method Details

requireWritingToTmpDirFirst

public boolean requireWritingToTmpDirFirst()

Description copied from interface: StoreFileTracker

Whether the implementation of this tracker requires you to write to temp directory first, i.e, does not allow broken store files under the actual data directory.

doAddNewStoreFiles

protected void doAddNewStoreFiles(Collection<StoreFileInfo> newFiles)
                           throws IOException

Specified by:

doAddNewStoreFiles in class StoreFileTrackerBase

Throws:

IOException

doAddCompactionResults

protected void doAddCompactionResults(Collection<StoreFileInfo> compactedFiles,
 Collection<StoreFileInfo> newFiles)
                               throws IOException

Specified by:

doAddCompactionResults in class StoreFileTrackerBase

Throws:

IOException

doLoadStoreFiles

protected List<StoreFileInfo> doLoadStoreFiles(boolean readOnly)
                                        throws IOException

Description copied from class: StoreFileTrackerBase

For primary replica, we will call load once when opening a region, and the implementation could choose to do some cleanup work. So here we use readOnly to indicate that whether you are allowed to do the cleanup work. For secondary replicas, we will set readOnly to true.

Specified by:

doLoadStoreFiles in class StoreFileTrackerBase

Throws:

IOException

doSetStoreFiles

protected void doSetStoreFiles(Collection<StoreFileInfo> files)
                        throws IOException

Specified by:

doSetStoreFiles in class StoreFileTrackerBase

Throws:

IOException

getStoreFiles

public List<StoreFileInfo> getStoreFiles(String familyName)
                                  throws IOException

Returns the store files available for the family. This methods performs the filtering based on the valid store files.

Parameters:

familyName - Column Family Name

Returns:

a set of StoreFileInfo for the specified family.

Throws:

IOException
