An `AsyncEventListener` instance is serviced by its own dedicated thread in which a callback method is invoked. Events that update a region are placed in an internal `AsyncEventQueue`, and one or more threads dispatch batches of events at a time to the listener implementation.
-You can configure an `AsyncEventQueue` to be either serial or parallel. A serial queue is deployed to one Geode member, and it delivers all of a region's events, in order of occurrence, to a configured `AsyncEventListener` implementation. A parallel queue is deployed to multiple Geode members, and each instance of the queue delivers region events, possibly simultaneously, to a local `AsyncEventListener` implementation.

-While a parallel queue provides the best throughput for writing events, it provides less control for ordering those events. With a parallel queue, you cannot preserve event ordering for a region as a whole because multiple Geode servers queue and deliver the region's events at the same time. However, the ordering of events for a given partition (or for a given queue of a distributed region) can be preserved.

However, the ordering of events for a given partition (or for a given queue of a distributed region) can be preserved.
For both serial and parallel queues, you can control 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 queues to persist to disk (instead of simply overflowing to disk) so that write-behind caching can pick up where it left off when a member shuts down and is later restarted.
-Optionally, a queue can use multiple threads to dispatch queued events. When you configure multiple threads for a serial queue, the logical queue that is hosted on a Geode member is divided into multiple physical queues, each with a dedicated dispatcher thread. You can then configure whether the threads dispatch queued events by key, by thread, or in the same order in which events were added to the queue. When you configure multiple threads for a parallel queue, each queue hosted on a Geode member is processed by dispatcher threads; the total number of queues created depends on the number of members that host the region.

@@ -61,11 +61,11 @@ Review the following guidelines before using an AsyncEventListener:
- If you use an `AsyncEventListener` to implement a write-behind cache listener, your code should check for the possibility that an existing database connection may have been closed due to an earlier exception. For example, check for `Connection.isClosed()` in a catch block and re-create the connection as needed before performing further operations.
- Use a serial `AsyncEventQueue` if you need to preserve the order of region events within a thread when delivering events to your listener implementation. Use parallel queues when the order of events within a thread is not important, and when you require maximum throughput for processing events. In both cases, serial and parallel, the order of operations on a given key is preserved within the scope of the thread.

- You can install a listener on more than one member to provide high availability and guarantee delivery for events, in the event that a member with the active `AsyncEventListener` shuts down. At any given time only one member has an active listener for dispatching events. The listeners on other members remain on standby for redundancy. For best performance and most efficient use of memory, install only one standby listener (redundancy of at most one).
- Install no more than one standby listener (redundancy of at most one) for performance and memory reasons.

For heap percentage, the controller used is the <%=vars.product_name%> resource manager, configured in conjunction with the JVM's garbage collector for optimum performance.
Configure data eviction as follows. You do not need to perform these steps in the sequence shown.
1. Decide whether to evict based on:
- Entry count (useful if your entry sizes are relatively uniform).
- Total bytes used. In partitioned regions, this is set using `local-max-memory`. In non-partitioned, it is set in `eviction-attributes`.
- - Percentage of application heap used. This uses the Geode resource manager. When the manager determines that eviction is required, the manager orders the eviction controller to start evicting from all regions where the eviction algorithm is set to `lru-heap-percentage`. Eviction continues until the manager calls a halt. Geode evicts the least recently used entry hosted by the member for the region. See [Managing Heap and Off-heap Memory](../../managing/heap_use/heap_management.html#resource_manager).

2. Decide what action to take when the limit is reached:
- Locally destroy the entry.
- Overflow the entry data to disk. See [Persistence and Overflow](../storing_data_on_disk/chapter_overview.html).
3. Decide the maximum amount of data to allow in the member for the eviction measurement indicated. This is the maximum for all storage for the region in the member. For partitioned regions, this is the total for all buckets stored in the member for the region - including any secondary buckets used for redundancy.
-4. Decide whether to program a custom sizer for your region. If you are able to provide such a class, it might be faster than the standard sizing done by Geode. Your custom class must follow the guidelines for defining custom classes and, additionally, must implement `org.apache.geode.cache.util.ObjectSizer`.

+<%=vars.product_name_long%> uses the following expiration types:
- **Time to live (TTL)**. The amount of time, in seconds, the object may remain in the cache after the last creation or update. For entries, the counter is set to zero for create and put operations. Region counters are reset when the region is created and when an entry has its counter reset. The TTL expiration attributes are `region-time-to-live` and `entry-time-to-live`.
- **Idle timeout**. The amount of time, in seconds, the object may remain in the cache after the last access. The idle timeout counter for an object is reset any time its TTL counter is reset. In addition, an entry’s idle timeout counter is reset any time the entry is accessed through a get operation or a netSearch . The idle timeout counter for a region is reset whenever the idle timeout is reset for one of its entries. Idle timeout expiration attributes are: `region-idle-time` and `entry-idle-time`.

6. For all but fixed partitioned regions, review the points at which you kick off rebalancing. Redundancy recovery is done automatically at the start of any rebalancing. This is most important if you run with no automated recovery after member crashes or joins. See [Rebalancing Partitioned Region Data](rebalancing_pr_data.html#rebalancing_pr_data).
During runtime, you can add capacity by adding new members for the region. For regions that do not use fixed partitioning, you can also kick off a rebalancing operation to spread the region buckets among all members.

You can generally get better performance if you use custom partitioning to group similar data within a region.

Grouping all data for a single customer can improve performance of data operations that work on customer data. Data aware function execution takes advantage of custom partitioning.

- **Fixed custom partitioning**. With fixed partitioning, you provide standard partitioning plus you specify the exact member where each data entry resides. You do this by assigning the data entry to a bucket and to a partition and by naming specific members as primary and secondary hosts of each partition.
This gives you complete control over the locations of your primary and any secondary buckets for the region. This can be useful when you want to store specific data on specific physical machines or when you need to keep data close to certain hardware elements.
Fixed partitioning has these requirements and caveats:
- - Geode cannot rebalance fixed partition region data because it cannot move the buckets around among the host members. You must carefully consider your expected data loads for the partitions you create.
+ - <%=vars.product_name%> cannot rebalance fixed partition region data because it cannot move the buckets around among the host members. You must carefully consider your expected data loads for the partitions you create.
- With fixed partitioning, the region configuration is different between host members. Each member identifies the named partitions it hosts, and whether it is hosting the primary copy or a secondary copy. You then program fixed partition resolver to return the partition id, so the entry is placed on the right members. Only one member can be primary for a particular partition name and that member cannot be the partition's secondary.
