Without cloning, Geode modifies the entry in place and so loses its reference to the old value. For delta events, the `EntryEvent` methods to retrieve the old and new values both return the new value. - -**Procedure** - -For every class in which you want delta propagation, implement the delta interface and update your methods to support delta propagation. Exactly how you do this depends on your application and object needs, but these steps describe the basic approach. - -1. Study the object contents to decide how to handle delta changes. - - Delta propagation has the same issues of distributed concurrency control as the distribution of full objects, but on a more detailed level. Some parts of your objects may be able to change independent of one another while others may always need to change together. Send deltas large enough to keep your data logically consistent. If, for example, field A and field B depend on each other, then your delta distributions should either update both fields or neither. As with regular updates, the fewer producers you have on a data region, the lower your likelihood of concurrency issues. - -2. In the application code that puts entries, put the fully populated object into the local cache. This usually means doing a `get` on the entry, unless you are sure it does not already exist anywhere in the distributed region. - - Even though you are planning to send only deltas, errors on the receiving end could cause Geode to request the full object, so you must provide it to the originating put method. Do this even in empty producers, with regions configured for no local data storage. - -3. Change each fieldâs update method to record information about the update. - - The information must be sufficient for `toDelta` to encode the delta and any additional required delta information when it is invoked. - -4. Write `hasDelta` to report on whether a delta is available. -5. When writing your serialization methods, `toDelta`, `fromDelta`, `toData`, `fromData`, be sure to exclude any fields used to manage delta state, which do not need to be sent. -6. Write `toDelta` to create a byte stream with the changes to the object and any other information that `fromDelta` will need to apply the changes. Before returning from `toDelta`, reset your delta state to indicate that there are no delta changes waiting to be sent. -7. Write `fromDelta` to decode the byte stream that `toDelta` creates and update the object. -8. Make sure you provide adequate synchronization to your object to maintain a consistent object state. - - If you do not use cloning, you will probably need to synchronize on reads and writes to avoid reading partially written updates from the cache. This might involve `toDelta`, `fromDelta`, and other object access and update methods. Additionally, your implementation should take into account the possibility of concurrent invocations of `fromDelta` and one or more of the object's update methods. - - http://git-wip-us.apache.org/repos/asf/incubator-geode/blob/381d0faa/geode-docs/nativeclient/delta-propagation/performance.html.md.erb ---------------------------------------------------------------------- diff --git a/geode-docs/nativeclient/delta-propagation/performance.html.md.erb b/geode-docs/nativeclient/delta-propagation/performance.html.md.erb deleted file mode 100644 index 435997e..0000000 --- a/geode-docs/nativeclient/delta-propagation/performance.html.md.erb +++ /dev/null @@ -1,48 +0,0 @@ ---- -title: Exceptions and Limitations ---- - -In some application scenarios, delta propagation does not show any significant performance benefits.

The system automatically does a full value distribution to the receiver where the problem occurs. This type of error includes: - - - Unavailable entry value in the receiving cache, either because the entry is missing or its value is null. In both cases, there is nothing to apply the delta to and the full value must be sent. This is most likely to occur if you destroy or invalidate your entries locally, either through application calls or through configured actions like eviction or entry expiration. - - `InvalidDeltaException` thrown by `fromDelta` method, programmed by you. This exception enables you to avoid applying deltas that would violate data consistency checks or other application requirements. Throwing this exception causes Geode to send the full value. - - Any error applying the delta in a client in server-to-client propagation. The client retrieves the full value from the server. -- **Problems creating or distributing the delta that cannot be fixed by distributing the full value.** These problems are caused by errors or exceptions in `hasDelta` or `toDelta`. In these cases, your `put` operation fails with an exception. - -## <a id="performance__section_39CE903E2C0C412E891C420C59AB4588" class="no-quick-link"></a>Performance Limitations - -Consider the following situations in which delta propagation adversely affects performance: - -- **Added costs of deserializing your objects to apply deltas**. Applying a delta requires the entry value to be deserialized. Once this is done, the object is stored back in the cache in deserialized form. This aspect of delta propagation only negatively impacts your system if your objects are not already being deserialized for other reasons, such as for indexing and querying or for listener operations. Once stored in deserialized form, there are reserialization costs for operations that send the object outside of the member, like values sent in response to netSearch or client requests, and storage to disk. The more operations that require reserialization, the higher the overhead of deserializing the object. -- **Cloning**. Cloning can affect performance. Not using cloning is risky, however, as you are modifying cached values in place. Make sure you synchronize your entry access to keep your cache from becoming inconsistent. -- **Problems applying the delta that cause the system to go back to the originator for the full entry value**. In this scenario, the overall operation costs more than sending the full entry value in the first place. The problem can be exacerbated if your delta is sent to a number of recipients, all or most of them request a full value, and the full value send requires the object to be serialized. -- **Disk I/O costs associated with overflow regions**. If you use eviction with overflow to disk, on-disk values must be brought into memory in order to apply the delta. This is much more costly than removing the reference to the disk copy, as you would do with a full value distribution into the cache. - -## <a id="performance__section_F7BC60C9E89B44BBA3D06995D52574AC" class="no-quick-link"></a>Configurations That Require Full Values - -Geode clients can always send deltas to the servers, and servers can usually sent deltas to clients. The following configurations require the servers to send full values to the clients, instead of deltas: - -- When the client's `gemfire.properties` setting `conflate-events` is set to `true`, the servers send full values for all regions. -- When the server region attribute `enable-subscription-conflation` is set to `true` and the client `gemfire.properties` setting `conflate-events` is set to `server`, the servers send full values for the region. -- Servers send full values to client regions that are configured to not cache dataâwith the `PROXY RegionShortcut` in their region attributes `refid`. - -To use the delta propagation feature, all updates on a key in a region must have value types that implement the `Delta` interface. You cannot mix object types for an entry key where some of the types implement delta and some do not. This is because, when a type implementing the delta interface is received for an update, the existing value for the key is cast to a `Delta` type to apply the received delta. - -## <a id="performance__section_2767204E1914425BB8160E4347615B71" class="no-quick-link"></a>General Limitations - -Sometimes `fromDelta` cannot be invoked because there is no object to apply the delta to in the receiving cache. When this happens, the system sends the full value. There are two possible scenarios: - -- If the system can determine beforehand that the receiver does not have a local copy, it sends the initial message with the full value. This is possible when regions are configured with no local data storage, as when you are using them to provide data update information to listeners. -- In less obvious cases, as when an entry has been locally deleted, first the delta is sent, then the receiver requests a full value and that is sent.

In terms of deserialization, to apply a change delta propagation requires a domain class instance and the `fromDelta` method. If you have set read-serialized to true, you will receive an `IPdxInstance` instead of a domain class instance and `IPdxInstance` does not have the `fromDelta` method required for delta propagation.
