[ https://issues.jboss.org/browse/ISPN-8729?page=com.atlassian.jira.plugin.... ] Gustavo Fernandes commented on ISPN-8729: ----------------------------------------- Sorry, by "command" I meant to write "operation", a specific Hot Rod request that can potentially block, for example, a script/task execution, or a listener registration with includeState=true or a listener configured with sync=true. Also, when indexing is enabled, unfortunately it can block on simple write commands since the machinery behind indexing is provided by Hibernate Search which in turn relies on Lucene, both which can block. Granted, indexing can be configured as async, but by default is it not. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
