by Michael Musgrove (JIRA)

[ https://issues.jboss.org/browse/JBTM-3049?page=com.atlassian.jira.plugin.... ] Michael Musgrove updated JBTM-3049: ----------------------------------- Description: Narayana configuration is performed through named configuration beans. For example the ObjectStoreEnvironmentBean has three instances for configuring different store types: * the action store (default) * the stateStore (with the name "stateStore") * the communicationsStore (with the name "communicationsStore") Each of the stores have their own getters and setters. We also have the arjPropertyManager API which returns the default configuration beans: {code} public static CoreEnvironmentBean getCoreEnvironmentBean(); public static CoordinatorEnvironmentBean getCoordinatorEnvironmentBean(); public static ObjectStoreEnvironmentBean getObjectStoreEnvironmentBean(); {code} For example the getObjectStoreEnvironmentBean() call returns the config for the action store. Historically (ie before we moved to using configuration beans) the user could set all config properties via the single instance of arjPropertyManager. For example, if the user wanted to disable file system sync'ing for the object store he would obtain an arjuna PropertyManager with which he could set a single property called OBJECTSTORE_SYNC and the setting would be applied to all writes to the object store. However, with the new/current config mechanism he would need to call the setter on each known instance of the ObjectStoreEnvironmentBean: {code} BeanPopulator.getNamedInstance(ObjectStoreEnvironmentBean.class, "communicationStore").setObjectStoreSync(false); BeanPopulator.getNamedInstance(ObjectStoreEnvironmentBean.class, "stateStore").setObjectStoreSync(false); BeanPopulator.getDefaultInstance(ObjectStoreEnvironmentBean.class).setObjectStoreSync(false); {code} This JIRA is to return to the original behaviour where calling the setters of the beans returned from arjPropertyManager should be applied to all named instances of the returned bean. The semantics of calling the getters needs be discussed and defined. was: Narayana configuration is performed through named configuration beans.

[JBoss JIRA] (JBTM-2920) Investigate the use of transactions within a reactive microservices environment

Motivation > Reactive microservice architecture is a trending architectural pattern. The reactive architecture could simply be defined as a system where messages are sent to a jms queue or a specialized event storage and other services are registered to, for being notified when an event is generated to be able to react on it. Synchronous calls from a service to a service are not meant to be a good practice in such system. Here all the communication between services is done with message passing through the event storage. > Such a system is expected to decouple data [3] where each microservice manages data, which needs for working, on its own. Still there are cases where some data coordination is needed. As the all communication is asynchronous it may be that we need to modify the transaction manager away from synchronous operations. One possibly good match seems to be the Saga transactions[4] and eventual consistency[5][6] but handling of them is fitting to the message driven system. The way of understanding Saga in microservice world could be overviewed at [15]. > Narayana transaction manager is good in managing Saga transactions where having long history experience from running it for WS[7] or managing consistency in NoSQL databases[8]. But Narayana is designed to manage transactions in synchronous way. The transaction context is normally passed along a RPC call where the transaction is finished after such synchronous call is returned back to the caller. > h2. Steps to go > The point here is to investigate on the topic of usage Saga in reactive architecture, gather working solutions - especially in Java world (some references eg. [9][10][11][12][13][14]), get experience in how they are working and on top of this experience considering implementation of the reactive approach with Narayana. It may be that Narayana requires some modification to execute optimally for such task and then it’s up to reconsideration if some greenfield implementation should be started. As the last step there should be created some sample project (ie. quickstart) where the usage of the implementation would be shown. > With that we expect usage of projects in Red Hat portfolio. The sample project would be probably implemented with usage of the Vert.x, meybe there could be considered usage of Infinispan or AMQ7 for handling events. > h2. Expected output > The expected output of this effort is > * A research document with state of the art. > ** Overview of what are the problem of the synchronous/blocking approach. > ** What are the other approaches that people have to this problem, > * A proof-of-concept implementation > ** Preferably with use of Narayana transaction manager prepare a service capable to manage transactions in world of reactive microservices > * An example/quickstart showing this in practical terms > ** A proof that a transaction manager can be made to work in an asynchronous environment. For example if you have a Vert.x event and it has to commit a transaction. The handler for that message currently does sync ops with transaction manager and that blocks. One of the goals for the project is to prevent blocking of threads in an async environment. > h2.
