Enum Table.TableOption

java.lang.Object

java.lang.Enum<Table.TableOption>

com.mapr.db.Table.TableOption

All Implemented Interfaces:

Serializable, Comparable<Table.TableOption>

Enclosing interface:

Table

public static enum Table.TableOption
extends Enum<Table.TableOption>

Following are different table options:

EXCLUDEID: If this option is set to true then rowkey (field "_id") won't be returned in the result of a find or findById operation. The default value of this option is false.

BUFFERWRITE: If this option is set to false then any insert, update, delete operation on the table would be synchronously sent in RPC to server. If the option is true, then buffering of these operations on the client are allowed and buffered updates are sent in batches to the server. The buffering operation is optimized for performance as it reduces the number of RPCs to the server.
The default value of this option is true, meaning data is buffered on the client and flushed to the server periodically.

KEEPINSERTIONORDER: If this option is set to true, then documents are returned to the end user with the fields in the same order that they were inserted into the document.
Suppose the document is inserted as { "name" : 1, "age" : 2, " }. On the server we will store it in lexicographical sorted format as { "age" : 2, "name" : 1}. However, if this option is not specified then on read we will return it as { "age" : 2, "name" : 1}, but if this option is specified, then on read we will return it as { "name" : 1, "age" : 2, " }. There is a little extra processing needed to maintain the fields in the document in insertion order. Hence applications that don't care about order should set this option to false. The default value of this option is true.

Method Detail

values

public static Table.TableOption[] 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 (Table.TableOption c : Table.TableOption.values())
    System.out.println(c);

Returns:

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

valueOf

public static Table.TableOption 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
