[jira] [Comment Edited] (ACCUMULO-3022) Limit size of table names
[ https://issues.apache.org/jira/browse/ACCUMULO-3022?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14074948#comment-14074948 ]

-------------------------------------------------------------------
How many, let's say, 200 character table names does it take to exhaust the Zookeeper memory and why would that be an Accumulo issue? Plucking a number out of the air, we could say that 2,500 table names of 200 characters each exhaust Zookeeper memory. If we arbitrarily limit table names to 100 characters then Zookeeper memory would be exhausted after 5,000 tables were created? It seems like table name size should be a guideline not an enforceable constraint. You have to know that six months after the constraint is added, someone will have a use case for longer table names and then we'll need to make the constraint configurable.
Oh.. and does this need to have 'Major' priority?
