<p>A multi-site installation consists of two or more loosely-coupled clusters. Each site manages its own cluster, but region data is distributed to remote sites using one or more logical connections.</p>
<p>The logical connections consist of a gateway sender in the sending site, and a gateway receiver in the receiving site. In a client/server installation, gateway senders and gateway receivers are configured in the server layer.</p>
<p>Gateway senders and receivers are defined at startup in the member caches. A site can use <em>serial</em> and/or <em>parallel</em> gateway sender configurations, as described in <a href="/docs/guide/115/topologies_and_comm/topology_concepts/multisite_overview.html#topic_9AA37B43642D4DE19072CA3367C849BA">Gateway Senders</a>.</p>
<p><img src="../../images/consistent_multisite.png" id="topic_70045702D3994BC692E75102CE01BD7C__image_BCD6320F34A645A7911AA25EDEA6D971" class="image" /></p>
<h2 id="consistency-for-wan-updates"><a id="topic_C74A0961937640B199396DC925D8D782" class="no-quick-link"></a>Consistency for WAN Updates</h2>
<p>Geode ensures that all copies of a region eventually reach a consistent state on all members and clients that host the region, including Geode members that distribute region events across a WAN.</p>
<p>Events are sent in batches from gateway senders to receivers. In order to avoid inconsistencies due
to partial reception of the events belonging to a transaction, you can configure gateway senders
using the <code>group-transaction-events</code> property to
ensure that events belonging to the same transaction are sent together in the same batch.
In order to use transaction event grouping:</p>
<ul>
<li>The <code>group-transaction-events</code> setting is supported only on serial senders with just one dispatcher thread, or on parallel senders.</li>
<li>The regions to which the transaction events belong must be replicated by the same set of gateway senders that also have this setting enabled.</li>
<li>This setting cannot be enabled if <code>enable-batch-conflation</code> is in effect.</li>
</ul>
<p><strong>Note:</strong>
If the above conditions are not fulfilled or under very high load traffic conditions, it may not be guaranteed that all the events for a transaction will be sent in the same batch, even if <code class="ph codeph">group-transaction-events</code> is enabled. The number of batches sent with incomplete transactions can be retrieved from the <code class="ph codeph">GatewaySenderMXBean</code> bean.</p>
<p>By default, potential WAN conflicts are resolved using a timestamp mechanism. You can optionally install a custom conflict resolver to apply custom logic when determining whether to apply a potentially conflicting update received over a WAN.</p>
<p><a href="/docs/guide/115/developing/distributed_regions/region_entry_versions.html#topic_CF2798D3E12647F182C2CEC4A46E2045">Consistency for Region Updates</a> describes how Geode ensures consistency within a cluster, in client caches, and when applying updates over a WAN. <a href="/docs/guide/115/developing/events/resolving_multisite_conflicts.html#topic_E97BB68748F14987916CD1A50E4B4542">Resolving Conflicting Events</a> provides more details about implementing a custom conflict resolver for WAN updates.</p>
<h2 id="discovery-for-multi-site-systems"><a id="topic_1742957C8D4B4F7590847EB8DB6CD4F7" class="no-quick-link"></a>Discovery for Multi-Site Systems</h2>
<p>Each Geode cluster in a WAN configuration uses locators to discover remote clusters as well as local members.</p>
<p>Each locator in a WAN configuration defines a unique <code>distributed-system-id</code> property that identifies the local cluster to which it belongs. A locator uses the <code>remote-locators</code> property to define the addresses of one or more locators in remote clusters to use for WAN distribution.</p>
<p>When a locator starts up, it contacts each locator that is configured in the <code>remote-locators</code> property to exchange information about the available locators and gateway receivers in the cluster. The locator also shares information about locators and gateway receivers in any other Geode clusters that have connected to the cluster. Connected clusters can then use the shared gateway receiver information to distribute region events according to their configured gateway senders.</p>
<p>Each time a new locator starts up or an existing locator shuts down, the changed information is broadcast to other connected Geode clusters.</p>
<h2 id="gateway-senders"><a id="topic_9AA37B43642D4DE19072CA3367C849BA" class="no-quick-link"></a>Gateway Senders</h2>
<p>A Geode cluster uses a <em>gateway sender</em> to distribute region events to another, remote Geode cluster. You can create multiple gateway sender configurations to distribute region events to multiple remote clusters, and/or to distribute region events concurrently to another remote cluster.</p>
<p>A gateway sender always communicates with a gateway receiver in a remote cluster. Gateway senders do not communicate directly with other cache server instances. See <a href="/docs/guide/115/topologies_and_comm/topology_concepts/multisite_overview.html#topic_4DB3D9CF01AD4F4899457D1250468D00">Gateway Receivers</a>.</p>
<p>Geode provides two types of gateway sender configurations: <em>serial</em> gateway senders and <em>parallel</em> gateway senders.</p>
<h2 id="serial-gateway-senders"><a id="topic_9AA37B43642D4DE19072CA3367C849BA__section_F7B3A17597B344F19A9E3546097AC5DB" class="no-quick-link"></a>Serial Gateway Senders</h2>
<p>A <em>serial gateway sender</em> funnels region events through a single Geode server in the local cluster to a gateway receiver in the remote Geode cluster. Although multiple regions can use the same serial gateway for distribution, a serial gateway uses a single logical event queue to dispatch events for all regions that use the gateway sender.</p>
<p><img src="../../images/serial_sender.png" id="topic_9AA37B43642D4DE19072CA3367C849BA__image_CEF888583FAC4CCBB0445F2BF8F15F20" class="image" width="576" /></p>
<p>Because a serial gateway sender has a single distribution point, it provides the most control over ordering region events as they are distributed across the WAN. However, a serial gateway sender provides only a finite amount of throughput, so it may be a performance bottleneck. As you add more regions and servers to the local cluster, you may need to configure additional serial gateway senders manually and isolate individual regions on specific serial gateway senders to handle the increased distribution traffic.</p>
<h2 id="parallel-gateway-senders"><a id="topic_9AA37B43642D4DE19072CA3367C849BA__section_5E989CEDC4F147788B393588CFF17106" class="no-quick-link"></a>Parallel Gateway Senders</h2>
<p>A <em>parallel gateway sender</em> distributes region events from each of the Geode servers that host a partitioned region. For a partitioned region, each server that hosts primary buckets for the region uses its own logical queue to distribute events for those buckets. As you add new servers to scale the partitioned region, WAN distribution throughput scales automatically with each new instance of the parallel gateway sender.</p>
<p><img src="../../images/parallel_sender.png" id="topic_9AA37B43642D4DE19072CA3367C849BA__image_D3BEABE6269543758DD0FAF4FFCD713A" class="image" width="576" /></p>
<p>Replicated regions cannot use a parallel gateway sender.</p>
<p>Although parallel gateway senders provide the best throughput for WAN distribution, they provide less control for event ordering. Event ordering for the region as a whole is not preserved, because multiple Geode servers distribute the regions events at the same time. However, the ordering of events for a given partition can be preserved. See <a href="/docs/guide/115/developing/events/configure_multisite_event_messaging.html#configure_multisite_event_messaging">Configuring Multi-Site (WAN) Event Queues</a>.</p>
<h2 id="gateway-sender-queues"><a id="topic_9AA37B43642D4DE19072CA3367C849BA__section_75F4588FEA404712963CE83FACB8ED1B" class="no-quick-link"></a>Gateway Sender Queues</h2>
<p>The queue that a gateway sender uses to distribute events to a remote site overflows to disk as needed, in order to prevent the Geode member from running out of memory. You can configure the maximum amount of memory that each queue uses, as well as the batch size and frequency for processing batches in the queue. You can also configure these queues to persist to disk, so that a gateway sender can pick up where it left off when its member shuts down and is later restarted.</p>
<p>By default gateway sender queues use 5 threads to dispatch queued events. With a serial gateway sender, the single, logical queue that is hosted on a member is divided into multiple physical queues (5 by default) each with a dedicated dispatcher thread. You can configure whether the threads dispatch queued events by key, by thread, or in the same order in which events were added to the queue. For a parallel gateway sender, each logical queue that is hosted on a member is processed simultaneously by multiple threads.</p>
<p>See <a href="/docs/guide/115/developing/events/configure_multisite_event_messaging.html#configure_multisite_event_messaging">Configuring Multi-Site (WAN) Event Queues</a>.</p>
<h2 id="timing-of-connections"><a id="GW_sender_connect" class="no-quick-link"></a>Timing of Connections</h2>
<p>When a gateway sender is created, it tries once to connect to
the gateway receiver.
If the gateway sender cannot connect,
the gateway sender does not retry until there is a batch of events to be sent.
At that time, the gateway sender tries again to connect to the gateway receiver.</p>
<p>During a normal initial startup,
one cluster site will start before the other cluster site.
The cluster site that starts first will not be connected
to the remote cluster site,
even after that other cluster site starts.
Only when data is to be sent will the connection be made.</p>
<h2 id="high-availability-for-gateway-senders"><a id="topic_9AA37B43642D4DE19072CA3367C849BA__section_70A4D850A5404429AD5CB483D2053F1A" class="no-quick-link"></a>High Availability for Gateway Senders</h2>
<p>When a serial gateway sender configuration is deployed to multiple Geode members, only one &ldquo;primary&rdquo; sender is active at a given time. All other serial gateway sender instances are inactive &ldquo;secondaries&rdquo; that are available as backups if the primary sender shuts down. Geode designates the first gateway sender to start up as the primary sender, and all other senders become secondaries. As gateway senders start and shut down, Geode ensures that the oldest running gateway sender operates as the primary.</p>
<p>A parallel gateway sender is deployed to multiple Geode members by default, and each member that hosts primary buckets for a partitioned region actively distributes data to the remote Geode site. When you use parallel gateway senders, high availability for WAN distribution is provided if you configure the partitioned region for redundancy. With a redundant partitioned region, if a member that hosts primary buckets fails or is shut down, then a Geode member that hosts a redundant copy of those buckets takes over WAN distribution for those buckets.</p>
<h2 id="stopping-gateway-senders"><a id="topic_9AA37B43642D4DE19072CA3367C849BA__section_aqm_2js_bq" class="no-quick-link"></a>Stopping Gateway Senders</h2>
<p>The scope of the gateway sender stop operation is the VM on which it is invoked. When you stop a parallel gateway sender using the <code>GatewaySender.stop()</code> or <code>gfsh stop gateway-sender</code>, the gateway sender is stopped on the individual node where this API is called. If the gateway sender is not parallel (serial), then the gateway sender will stop on the local VM, and the secondary gateway sender will become primary and start dispatching events. The gateway sender will wait for <code>GatewaySender.MAXIMUM_SHUTDOWN_WAIT_TIME</code> seconds before stopping itself (by default, this value is set to 0). You can set this Java system property when starting the server member in <code>gfsh</code>. If the Java system property is set to -1, then the gateway sender process will wait until all events are dispatched from the queue before stopping.</p>
<p><strong>Note:</strong>
Use extreme caution when stopping parallel gateway senders by using the <code>GatewaySender.stop()</code> API or <code>gfsh stop gateway-sender</code> command.</p>
<p>The API and gfsh command stops the parallel gateway sender in one member, which causes data loss because events to buckets in that member will be dropped by the stopped sender. The partitioned region does not failover in this scenario since the member is still running. Instead, to ensure that the remaining events are sent, shut down the entire member to ensure proper failover of partition region events. When a member with the stopped parallel sender is shut down, the other parallel gateway sender members hosting the partition region become primary and deliver the remaining events. In addition, if the whole cluster is brought down after stopping an individual parallel gateway sender, then events queued on that gateway sender can be lost.</p>
<h2 id="pausing-gateway-senders"><a id="topic_9AA37B43642D4DE19072CA3367C849BA__section_hdt_2js_bq" class="no-quick-link"></a>Pausing Gateway Senders</h2>
<p>Similar to stopping a gateway sender, the scope of pausing a gateway sender is the VM on which it is invoked. Pausing a gateway sender temporarily stops the dispatching of events from the underlying queue. Note that events are still queued into the queue. In case where the gateway sender is parallel, the gateway sender is paused on the individual node where the <code>GatewaySender.pause()</code> API is called or the <code>gfsh pause gateway-sender</code> command is invoked. The parallel gateway senders on other members can still dispatch events. In case where the paused gateway sender is not parallel (serial) and is not primary, then the primary gateway sender will still continue dispatching events. The batch of events that are in the process of being dispatched are dispatched regardless of the state of the pause operation. We can expect a maximum of one batch of events being received at the gateway receiver even after the gateway senders have been paused.</p>
<h2 id="gateway-receivers"><a id="topic_4DB3D9CF01AD4F4899457D1250468D00" class="no-quick-link"></a>Gateway Receivers</h2>
<p>A gateway receiver configures a physical connection for receiving region events from gateway senders in one or more remote Geode clusters.</p>
<p>A gateway receiver applies each region event to the same region or partition that is hosted in the local Geode member. (An exception is thrown if the receiver receives an event for a region that it does not define.)</p>
<p>Gateway senders use any available gateway receiver in the target cluster to send region events. You can deploy gateway receiver configurations to multiple Geode members as needed for high availability and load balancing, however you can only host one gateway receiver per member.</p>
<p>After you create a gateway receiver, you can configure the gateway receiver to start automatically or to require a manual start.
By default, the gateway receiver starts automatically (<code>manual-start</code> is set to false).</p>
<p>After you create and start a new gateway receiver at one WAN site, you can execute the <a href="/docs/guide/115/tools_modules/gfsh/command-pages/load-balance.html#concept_fn2_qls_5q">load-balance gateway-sender</a> command in <code>gfsh</code> for existing remote gateway senders so that the new receiver can pick up connections to gateway senders at different sites. You invoke this command on the gateway senders to redistribute connections more evenly among all the gateway receivers. Another option is to use the <code>GatewaySender.rebalance</code> Java API.</p>
<p>See <a href="/docs/guide/115/topologies_and_comm/multi_site_configuration/setting_up_a_multisite_system.html#setting_up_a_multisite_system__section_E3A44F85359046C7ADD12861D261637B">Configure Gateway Receivers</a>.</p>
