|
| <td><p>Specifies atomic-only cache behaviour. In this mode distributed transactions and distributed |
| locking are not supported. Disabling transactions and locking allows to achieve much higher |
| performance and throughput ratios. |
| <p> |
| In addition to transactions and locking, one of the main differences to <a class="xref" href="Apache.Ignite.Core.Cache.Configuration.CacheAtomicityMode.html#Apache_Ignite_Core_Cache_Configuration_CacheAtomicityMode_Atomic">Atomic</a> mode |
| is that bulk writes, such as <a class="xref" href="Apache.Ignite.Core.Cache.ICache-2.html#Apache_Ignite_Core_Cache_ICache_2_PutAll_System_Collections_Generic_IEnumerable_System_Collections_Generic_KeyValuePair__0__1___">PutAll(IEnumerable<KeyValuePair<TK, TV>>)</a> |
| and <a class="xref" href="Apache.Ignite.Core.Cache.ICache-2.html#Apache_Ignite_Core_Cache_ICache_2_RemoveAll_System_Collections_Generic_IEnumerable__0__">RemoveAll(IEnumerable<TK>)</a> methods, |
| become simple batch operations which can partially fail. In case of partial |
| failure, <a class="xref" href="Apache.Ignite.Core.Cache.CachePartialUpdateException.html">CachePartialUpdateException</a>will be thrown which will contain a list of keys |
| for which the update failed. It is recommended that bulk writes are used |
| whenever multiple keys need to be inserted or updated in cache, as they reduce number of network trips and |
| provide better performance. |
| <p> |
| Note that even without locking and transactions, <a class="xref" href="Apache.Ignite.Core.Cache.Configuration.CacheAtomicityMode.html#Apache_Ignite_Core_Cache_Configuration_CacheAtomicityMode_Atomic">Atomic</a> mode still provides |
| full consistency guarantees across all cache nodes. |
| <p> |
| Also note that all data modifications in <a class="xref" href="Apache.Ignite.Core.Cache.Configuration.CacheAtomicityMode.html#Apache_Ignite_Core_Cache_Configuration_CacheAtomicityMode_Atomic">Atomic</a> mode are guaranteed to be atomic |
| and consistent with writes to the underlying persistent store, if one is configured. </p> |
