Infinispan Query module should load entities using getAll --------------------------------------------------------- Key: ISPN-951 URL: https://issues.jboss.org/browse/ISPN-951 Project: Infinispan Issue Type: Enhancement Components: Embedded Querying Reporter: Sanne Grinovero Assignee: Gustavo Fernandes Ideally we should use a method like {{List getAll(Object[] keys)}} from Infinispan core, but that doesn't exist yet. Such a method would be able to split the keys in such a way to minimize the number of RPCs needed to "cover" the set of all segments needed to satisfy the query, so to find the minimum set of nodes available which need to be contacted to retrieve all entries. Loading of each entry doesn't necessarily need to happen sequentially, I guess the minimum set of RPCs should be executed in parallel, then we block until they are all returned and need to restore the order of the list (the order of the return elements need to match the order of their respective keys from the parameter). We should implement such a method, or until that's possible it might be easier to run each individual get in a {{getAsync}} so that the latency of a Query returning for example 100 entries doesn't scale up to 100 sequential RPCs. Requires migration to new Loader API from Hibernate Search.
