improve automatic space reclamation.
> enhance existing automatic space reclamation for tables

> Key: DERBY-512
> URL: https://issues.apache.org/jira/browse/DERBY-512
> Project: Derby
> Issue Type: Improvement
> Components: Store
> Reporter: Mike Matrigali
> Priority: Minor
>
> The current space reclamation system does a good job of reusing space if
> inserts follow deletes and if the
> deletes result in freeing complete pages. In other cases unused space can
> grow in tables and can only
> be reclaimed by explicitly calling the compress table interfaces by hand.
> As a zero admin database, derby should provide some way to automatically
> reclaim this space.
