            <title>[SERVER-28602] Add RecoveryUnit setTimestamp() and selectSnapshot() to storage API</title>
                <link>https://jira.mongodb.org/browse/SERVER-28602</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;New function: Supply a timestamp for a transaction&lt;br/&gt;
&lt;tt&gt;virtual Status RecoveryUnit::setTimestamp(SnapshotName timestamp);&lt;/tt&gt;&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;This function may only be called in a unit of work.  (Cannot set timestamps without an open transaction.)&lt;/li&gt;
	&lt;li&gt;It is presumed that only transactions that perform writes will call this function, to assign  timestamps.  MongoDB aborts all read transactions anyway, so assigning timestamps for such transactions would have no effect.&lt;/li&gt;
	&lt;li&gt;If this function is called multiple times in a WriteUnitOfWork, the timestamps may only move forward (or stay the same).  An error will be returned if setTimestamp() attempts to assign a timestamp that is sooner than a previously assigned timestamp for a transaction.&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;New function: Use a timestamp to read at a point in time&lt;br/&gt;
&lt;tt&gt;virtual Status RecoveryUnit::selectSnapshot(SnapshotName timestamp);&lt;/tt&gt;&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;This function may optionally be called prior to calling getCursor() on a RecordStore.&lt;/li&gt;
	&lt;li&gt;This function could be called again after calling getCursor(); this would be useful to, say, change to a more recent snapshot at query yield time.  This is the current behavior of read-concern-majority, for example.&lt;/li&gt;
	&lt;li&gt;This function cannot be called while a transaction is active: invariant(!inATransaction)&lt;/li&gt;
	&lt;li&gt;The data returned from the cursor will reflect data from transactions that have committed with write timestamps up to and including time.  If a transaction had multiple timestamps assigned to individual writes, such a transaction could be sliced by the read operation.  Slicing is only expected to occur for transactions that were committed by the replication machinery for oplog application.&lt;/li&gt;
	&lt;li&gt;The body of this function will set a member variable for the snapshot time in the RecoveryUnit.  At the next begin_transaction, it will use the stored time as the read_timestamp parameter.&lt;/li&gt;
&lt;/ul&gt;
