Micro-optimizations for read operations --------------------------------------- Key: ISPN-6802 URL: https://issues.jboss.org/browse/ISPN-6802 Project: Infinispan Issue Type: Task Components: Core Affects Versions: 9.0.0.Alpha2 Reporter: Dan Berindei Assignee: Dan Berindei Fix For: 9.0.0.Alpha4 * L1 entries are written to the data container by L1TxInterceptor/L1NonTxInterceptor directly, so there is no reason to commit the context entries in EntryWrappingInterceptor or to clear the locks in the locking interceptors. * ClearCommands can no longer be wrapped in PrepareCommands, so we can stop the state transfer in {{EntryWrappingInterceptor.visitClearCommand()}} instead of checking the type for each command. * In transactional caches, a read operation without an explicit transaction triggers two queries for the current transaction to the transaction manager, which usually means 2 thread-local lookups. * IsMarshallerInterceptor shouldn't do anything unless there is an asynchronous store * Transactional remote get commands use NonTxInvocationInterceptor instead of SingleKeyNonTxInterceptor. * Configuration attributes should be cached, as reading them requires accessing multiple instances + a cast in Attribute.get()
