Enum Constant Summary

Enum Constants

Enum Constant	Description
CONCURRENT	Column files are synchronized to the destination file system immediately when writing finishes, but the writing thread is free to accept new jobs.
FINAL	Column files are synchronized to the destination file system when all writing finishes.
IMMEDIATE	Column files are synchronized to the destination file system immediately when writing finishes, blocking the thread that wrote them until complete.

Method Summary

Modifier and Type	Method	Description

Enum Constant Details

IMMEDIATE

public static final SyncMode IMMEDIATE

Column files are synchronized to the destination file system immediately when writing finishes, blocking the thread that wrote them until complete. This is the default, unless .

CONCURRENT

public static final SyncMode CONCURRENT

Column files are synchronized to the destination file system immediately when writing finishes, but the writing thread is free to accept new jobs. Synchronization jobs are waited for when all writing finishes.

FINAL

public static final SyncMode FINAL

Column files are synchronized to the destination file system when all writing finishes.

Method Details

values

public static SyncMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared.

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static SyncMode valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

lookup

@Nullable public static SyncMode lookup(@NotNull String exceptionPrefix, @Nullable String name)

makeSyncOperator

public abstract SyncOperator makeSyncOperator(@NotNull String name, int numColumns, int numPartitions)
