> When data is not available in the data cache, OpenJPA dynamically creates SQL to look
up the requested data. OpenJPA should more aggressively cache this SQL to accelerate pathways
from a cache miss to the database.
> The generated SQL takes a number of factors into account, including the requested records,
transaction status, currently-loaded data, and the current fetch configuration. Any caching
would need to account for these factors as well.
