Summary: Schema and table filter
Key: METAMODEL-14
URL: https://issues.apache.org/jira/browse/METAMODEL-14
Project: Metamodel
Issue Type: New Feature
Reporter: Kasper Sørensen
Assignee: Henry Saputra
We sometimes encounter very big databases (mostly JDBC based) and even some
DBAs who get annoyed that we use the JDBC metadata API to query for the schema
structure. So...
Make a common abstraction for filtering out certain schemas or tables. For
instance a schema filter could provide either a pattern or a fixed set of
schemas to include in the data context.
It should be up to the datacontext to determine how to filter them. And at the
least we should provide an interceptor implementation that will work for every
datacontext implementation. Especially for JDBC it is important that the
datacontext is aware of the filter, so it can apply it in the metadata calls to
the DB.
