Method Detail

listPartition

protected List<StoragePathInfo> listPartition(StoragePath partitionPath)
                                       throws IOException

Return all the files in the partition by reading from the Metadata Table.

Overrides:

listPartition in class AbstractTableFileSystemView

Parameters:

partitionPath - The absolute path of the partition

Throws:

IOException

getAllPartitionPaths

protected List<String> getAllPartitionPaths()
                                     throws IOException

Overrides:

getAllPartitionPaths in class AbstractTableFileSystemView

Returns:

A list of relative partition paths of all partitions.

Throws:

IOException - upon error.

listPartitions

protected Map<Pair<String,StoragePath>,List<StoragePathInfo>> listPartitions(List<Pair<String,StoragePath>> partitionPathList)
                                                                      throws IOException

Overrides:

Parameters:

partitionPathList - A list of pairs of the relative and absolute paths of the partitions.

Returns:

all the files from the partitions.

Throws:

IOException - upon error.

reset

public void reset()

Description copied from class: AbstractTableFileSystemView

Clears the partition Map and reset view states.

NOTE: The logic MUST BE guarded by the write lock.

Specified by:

reset in interface SyncableFileSystemView

Overrides:

reset in class AbstractTableFileSystemView

sync

public void sync()

Description copied from class: AbstractTableFileSystemView

Syncs the file system view from storage to memory. Performs complete reset of file-system view. Subsequent partition view calls will load file slices against the latest timeline.

NOTE: The logic MUST BE guarded by the write lock.

Specified by:

sync in interface SyncableFileSystemView

Overrides:

sync in class IncrementalTimelineSyncFileSystemView

close

public void close()

Description copied from interface: SyncableFileSystemView

Allow View to release resources and close.

Specified by:

close in interface SyncableFileSystemView

Overrides:

close in class HoodieTableFileSystemView
