- All Implemented Interfaces:
Serializable,Comparable<CacheWriteSynchronizationMode>
public enum CacheWriteSynchronizationMode extends Enum<CacheWriteSynchronizationMode>
Mode indicating how Ignite should wait for write replies from other nodes. Default value isPRIMARY_SYNC}, which means that Ignite will wait for write or commit to complete onprimarynode, but will not wait for backups to be updated.Note that regardless of write synchronization mode, cache data will always remain fully consistent across all participating nodes.
Write synchronization mode may be configured via
CacheConfiguration.getWriteSynchronizationMode()configuration property.

Enum Constant Summary
Enum Constants Enum Constant Description FULL_ASYNCFlag indicating that Ignite will not wait for write or commit responses from participating nodes, which means that remote nodes may get their state updated a bit after any of the cache write methods complete, or afterTransaction.commit()method completes.FULL_SYNCFlag indicating that Ignite should wait for write or commit replies from all nodes.PRIMARY_SYNCThis flag only makes sense forCacheMode.PARTITIONEDandCacheMode.REPLICATEDmodes.

FULL_SYNC
public static final CacheWriteSynchronizationMode FULL_SYNC
Flag indicating that Ignite should wait for write or commit replies from all nodes. This behavior guarantees that whenever any of the atomic or transactional writes complete, all other participating nodes which cache the written data have been updated.
-
FULL_ASYNC
public static final CacheWriteSynchronizationMode FULL_ASYNC
Flag indicating that Ignite will not wait for write or commit responses from participating nodes, which means that remote nodes may get their state updated a bit after any of the cache write methods complete, or afterTransaction.commit()method completes.
-
PRIMARY_SYNC
public static final CacheWriteSynchronizationMode PRIMARY_SYNC
This flag only makes sense forCacheMode.PARTITIONEDandCacheMode.REPLICATEDmodes. When enabled, Ignite will wait for write or commit to complete onprimarynode, but will not wait for backups to be updated.

values
public static CacheWriteSynchronizationMode[] 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 (CacheWriteSynchronizationMode c : CacheWriteSynchronizationMode.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static CacheWriteSynchronizationMode 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 nameNullPointerException- if the argument is null
-
fromOrdinal
@Nullable public static @Nullable CacheWriteSynchronizationMode fromOrdinal(int ord)
Efficiently gets enumerated value from its ordinal.- Parameters:
ord- Ordinal value.- Returns:
- Enumerated value or
nullif ordinal out of range.
