Enum Constant Summary

Enum Constants

Enum Constant and Description
IGNORE No need to move the file, used in case of replication to s3.
KEEP_EXISTING This corresponds to INSERT INTO and LOAD DATA.
OVERWRITE_EXISTING This corresponds to REPL LOAD where if we re-apply the same event then need to overwrite the file instead of making a duplicate copy.
REPLACE_ALL This corresponds to INSERT OVERWRITE and REPL LOAD for INSERT OVERWRITE event.

Method Summary

Enum Constant Detail

REPLACE_ALL

public static final LoadTableDesc.LoadFileType REPLACE_ALL

This corresponds to INSERT OVERWRITE and REPL LOAD for INSERT OVERWRITE event. Remove all existing data before copy/move

KEEP_EXISTING

public static final LoadTableDesc.LoadFileType KEEP_EXISTING

This corresponds to INSERT INTO and LOAD DATA. If any file exist while copy, then just duplicate the file

OVERWRITE_EXISTING

public static final LoadTableDesc.LoadFileType OVERWRITE_EXISTING

This corresponds to REPL LOAD where if we re-apply the same event then need to overwrite the file instead of making a duplicate copy. If any file exist while copy, then just overwrite the file

IGNORE

public static final LoadTableDesc.LoadFileType IGNORE

No need to move the file, used in case of replication to s3. If load type is set to ignore, then only the file operations(move/rename) is ignored at load table/partition method. Other operations like statistics update, event notification happens as usual.

Method Detail

values

public static LoadTableDesc.LoadFileType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (LoadTableDesc.LoadFileType c : LoadTableDesc.LoadFileType.values())
    System.out.println(c);

Returns:

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

valueOf

public static LoadTableDesc.LoadFileType 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
