enum db::TxCompletionMode Transaction completion mode. This determines whether the transaction will be flushed to disk immediately, or at a later time that would provide better performance at the cost of durability. See also: Database::tx_commit, Database::tx_abort, Database::set_default_completion_mode, Database::get_default_completion_mode, Database::create, Database::open, Table::set_sort_order Enumerator: DB_DEFAULT_COMPLETION  Use storage settings to determine completion mode. See also: Database::get_default_completion_mode, Database::set_default_completion_mode DB_LAZY_COMPLETION  Perform lazy completion. The transaction status is not written to disk, which may cause the transaction to abort if a crash occurs before the journal is flushed. Call Database::tx_flush to force lazily completed transactions to complete. DB_GROUP_COMPLETION  Perform group completion. The transaction will wait for all other active transactions to be committed and perform the commit for all transactions as a group. This improves performance when several transactions are active at the same time by reducing the amount of disk I/O that is performed. If no other transactions are active, or if 50 milliseconds elapses before the other transactions are committed, the transaction will stop waiting and complete immediately. Database::tx_commit will not return until the transaction is fully flushed to disk. DB_FORCED_COMPLETION  Force completion immediately. The transaction will be fully flushed to disk before Database::tx_commit returns.
