Subject [jira] [Created] (DERBY-6105) Implement resource constraints for Derby.
Date Tue, 12 Mar 2013 12:47:13 GMT
Rick Hillegas created DERBY-6105:

             Summary: Implement resource constraints for Derby.
                 Key: DERBY-6105
                 URL: https://issues.apache.org/jira/browse/DERBY-6105
             Project: Derby
          Issue Type: Improvement
          Components: SQL, Store
    Affects Versions:
            Reporter: Rick Hillegas

Resource constraints could help protect Derby from denial-of-service attacks. Resource constraints
would be useful for throttling runaway users or enforcing quota licenses in multi-tenant situations,
i.e., where an installation simultaneously runs multiple instances of the same application
or several different applications. Resource constraints are discussed in the following email
thread: http://apache-database.10148.n7.nabble.com/How-to-limit-Derby-size-on-Disk-td127797.html

The following file system constraints might be interesting:

1) Limits on the total space consumed by a database.

2) Limits on the total space consumed by an individual table.

3) Limits on the number of rows in an individual table.

4) Limits on the total space consumed by all tables owned by a given user or role.
