Problem
Flush() is incorrectly named and/or incorrectly implemented. I have no way of flushing a critical object to disk without necessarily making all data store on an aggressive time interval. This would be inappropriate.
Expectation
"Flush - (v) To copy data from a temporary storage area such as RAM to a more permanent storage medium such as a disk."
Any ObjectStore::Flush() method should fit the above definition, or should be renamed to convey its actual behavior.
Actual
ObjectStore::Flush() does not perform a flush operation, it performs a purge (it removes all dictionaries from _primaryStore and performs no saves before doing so. If you store an object, call flush, then shutdown the session the resulting .coll and .jnl files are 0 length (empty). This is highly undesirable behavior.
Proposal
ObjectStore::Flush() should instead signal StoreManager::SaveDBThreadMethod() so that the database/collection is stored as one would expect. Right now this method only signals during shutdown, or due to a signal timeout (default appears to be 5 minutes.)
