  <div class="markdown level0 summary"><p>Grid cache transaction. 
<p>
Cache transactions support the following isolation levels:
<ul><li><a class="xref" href="Apache.Ignite.Core.Transactions.TransactionIsolation.html#Apache_Ignite_Core_Transactions_TransactionIsolation_ReadCommitted">ReadCommitted</a> isolation level 
        means that always a committed value will be provided for read operations. With this isolation 
        level values are always read from cache global memory or persistent store every time a value 
        is accessed. In other words, if the same key is accessed more than once within the same transaction, 
        it may have different value every time since global cache memory may be updated concurrently by 
        other threads.</li><li><a class="xref" href="Apache.Ignite.Core.Transactions.TransactionIsolation.html#Apache_Ignite_Core_Transactions_TransactionIsolation_RepeatableRead">RepeatableRead</a> isolation level 
        means that if a value was read once within transaction, then all consecutive reads will provide 
        the same in-transaction value. With this isolation level accessed values are stored within 
        in-transaction memory, so consecutive access to the same key within the same transaction will always 
        return the value that was previously read or updated within this transaction. If concurrency is 
<a class="xref" href="Apache.Ignite.Core.Transactions.TransactionConcurrency.html#Apache_Ignite_Core_Transactions_TransactionConcurrency_Pessimistic">Pessimistic</a>, then a lock on the key will be 
acquired prior to accessing the value.</li><li><a class="xref" href="Apache.Ignite.Core.Transactions.TransactionIsolation.html#Apache_Ignite_Core_Transactions_TransactionIsolation_Serializable">Serializable</a> isolation level means 
that all transactions occur in a completely isolated fashion, as if all transactions in the system 
had executed serially, one after the other. Read access with this level happens the same way as with 
<a class="xref" href="Apache.Ignite.Core.Transactions.TransactionIsolation.html#Apache_Ignite_Core_Transactions_TransactionIsolation_RepeatableRead">RepeatableRead</a> level. However, in 
<a class="xref" href="Apache.Ignite.Core.Transactions.TransactionConcurrency.html#Apache_Ignite_Core_Transactions_TransactionConcurrency_Optimistic">Optimistic</a> mode, if some transactions cannot be 
serially isolated from each other, then one winner will be picked and the other transactions in 
conflict will result in <code>TransactionOptimisticException</code> being thrown on Java side.</li></ul>
Cache transactions support the following concurrency models:
<ul><li><a class="xref" href="Apache.Ignite.Core.Transactions.TransactionConcurrency.html#Apache_Ignite_Core_Transactions_TransactionConcurrency_Optimistic">Optimistic</a> - in this mode all cache 
        operations 
        are not distributed to other nodes until <a class="xref" href="Apache.Ignite.Core.Transactions.ITransaction.html#Apache_Ignite_Core_Transactions_ITransaction_Commit">Commit()</a>.
        In this mode one <code>PREPARE</code> message will 
        be sent to participating cache nodes to start acquiring per-transaction locks, and once all nodes 
        reply <code>OK</code> (i.e. <code>Phase 1</code> completes successfully), a one-way <code>COMMIT</code> message is sent
        without waiting for reply. If it is necessary to know whenever remote nodes have committed as well, 
        synchronous commit or synchronous rollback should be enabled via 
<code>CacheConfiguration.setWriteSynchronizationMode</code>.
<p>
Note that in this mode, optimistic failures are only possible in conjunction with
<a class="xref" href="Apache.Ignite.Core.Transactions.TransactionIsolation.html#Apache_Ignite_Core_Transactions_TransactionIsolation_Serializable">Serializable</a> isolation level. In all other cases, 
optimistic transactions will never fail optimistically and will always be identically ordered on all 
participating Ignite nodes.</li><li><a class="xref" href="Apache.Ignite.Core.Transactions.TransactionConcurrency.html#Apache_Ignite_Core_Transactions_TransactionConcurrency_Pessimistic">Pessimistic</a> - in this mode a lock is 
acquired on all cache operations with exception of read operations in 
<a class="xref" href="Apache.Ignite.Core.Transactions.TransactionIsolation.html#Apache_Ignite_Core_Transactions_TransactionIsolation_ReadCommitted">ReadCommitted</a> mode. All optional filters passed 
into cache operations will be evaluated after successful lock acquisition. Whenever 
<a class="xref" href="Apache.Ignite.Core.Transactions.ITransaction.html#Apache_Ignite_Core_Transactions_ITransaction_Commit">Commit()</a> is called, a single one-way <code>COMMIT</code> 
message is sent to participating cache nodes without waiting for reply. Note that there is no reason 
for distributed <code>PREPARE</code> step, as all locks have been already acquired. Just like with 
optimistic mode, it is possible to configure synchronous commit or rollback and wait till 
transaction commits on all participating remote nodes.</li></ul>
<p>
In addition to standard <code>CacheAtomicityMode.TRANSACTIONAL</code> behavior, Ignite also supports
a lighter <code>CacheAtomicityMode.ATOMIC</code> mode as well. In this mode distributed transactions
and distributed locking are not supported. Disabling transactions and locking allows to achieve much higher
performance and throughput ratios. It is recommended that <code>CacheAtomicityMode.TRANSACTIONAL</code> mode
is used whenever full <code>ACID</code>-compliant transactions are not needed.
<example>
    You can use cache transactions as follows:<p>
<pre><code>using (var tx = cache.Ignite.GetTransactions().TxStart())
{
    int v1 = cache&lt;string, int>.Get(&quot;k1&quot;);

    // Check if v1 satisfies some condition before doing a put.
    if (v1 > 0)
        cache.Put&lt;string, int>(&quot;k1&quot;, 2);

    cache.Remove(&quot;k2&quot;);

    // Commit the transaction.
    tx.Commit();
}</code></pre>
<p></example></p>
