Jimmy Xiang commented on HBASE-7022: ------------------------------------ Currently, I think ZooKeeper#multi doesn’t help very much since it's synchronous, transactional, and doesn’t support something like upsert in SQL (i.e. create it if a node doesn’t exist, otherwise, update its data). It supports batch of size less than 1MB. If we can have an asynchronous, non-transactional multi zookeeper client function, which also supports upsert, it will really help. > Use multi to batch offline regions in zookeeper > ----------------------------------------------- > > Key: HBASE-7022 > URL: https://issues.apache.org/jira/browse/HBASE-7022 > Project: HBase > Issue Type: Bug > Reporter: Jimmy Xiang > Assignee: Jimmy Xiang > > Bulk assigner needs to set regions offline in zookeeper one by one.
