SQLITE_DBSTATUS_CACHE_WRITE This parameter returns the number of dirty cache entries that have been written to disk. Specifically, the number of pages written to the wal file in wal mode databases, or the number of pages written to the database file in rollback mode databases. Any pages written as part of transaction rollback or database recovery operations are not included. If an IO or other error occurs while writing a page to disk, the effect on subsequent SQLITE_DBSTATUS_CACHE_WRITE requests is undefined.

SQLITE_DBSTATUS_CACHE_SPILL This parameter returns the number of dirty cache entries that have been written to disk in the middle of a transaction due to the page cache overflowing. Transactions are more efficient if they are written to disk all at once. When pages spill mid-transaction, that introduces additional overhead. This parameter can be used help identify inefficiencies that can be resolved by increasing the cache size.
^(SQLITE_DBSTATUS_DEFERRED_FKS This parameter returns zero for the current value if and only if all foreign key constraints (deferred or immediate) have been resolved.
