HotRod Transaction Cache PESSIMISTIC locking mode is not locking the key in another transaction ----------------------------------------------------------------------------------------------- Key: ISPN-9412 URL: https://issues.jboss.org/browse/ISPN-9412 Project: Infinispan Issue Type: Bug Reporter: Diego Lovison Priority: Critical I am expecting the thread 2 be blocked in `cache.put(k1, v1)` until thread 1 has committed the transaction According to the docs, using Pessimistic transactional cache, when cache.put(k1,v1) returns, k1 is locked and no other transaction running anywhere in the cluster can write to it. Reading k1 is still possible. The lock on k1 is released when the transaction completes (commits or rollbacks). Cache Configuration {code:java} return new org.infinispan.configuration.cache.ConfigurationBuilder() .clustering().cacheMode(CacheMode.DIST_SYNC) .jmxStatistics().enable() .transaction() .cacheStopTimeout(0L) .transactionManagerLookup(new EmbeddedTransactionManagerLookup()) .lockingMode(LockingMode.PESSIMISTIC) .locking().isolationLevel(IsolationLevel.REPEATABLE_READ) .build(); {code}
