Subject [jira] [Commented] (ACCUMULO-3022) Limit size of table names
Date Fri, 25 Jul 2014 21:26:40 GMT


David Medinets commented on ACCUMULO-3022:

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.
