Summary: Do not send previous value to client node for invoke() when possible Key: IGNITE-3471 URL: https://issues.apache.org/jira/browse/IGNITE-3471 Project: Ignite Issue Type: Task Components: cache Affects Versions: 1.4 Reporter: Alexey Goncharuk Currently for invoke() or invokeAll() methods we send previous cache value to near node and apply EntryProcessor locally to get a return value. This can induce a significant overhead when cache value is much larger than entry processor result. For many cases this can be avoided, e.g. {code} try (tx = txStart()) { cache.invoke(key, EP); // No need to send previous value to client in this case. tx.commit(); } {code} Note that we need to add additional handling of such a case: {code} try (tx = txStart()) { cache.invoke(key, EP); // No need to send previous value to client in this case. cache.get(key); // This should actually get the current cache value from primary node and apply an entry processor locally to get the updated value. tx.commit(); } {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
