A complex result set bias the decision toward the use of co-routines. </ol> } chng {2017-10-24 (3.21.0)} { <li> Take advantage of the atomic-write capabilities in the [https://en.wikipedia.org/wiki/F2FS|F2FS filesystem] when available, for greatly reduced transaction overhead. This currently requires the [SQLITE_ENABLE_BATCH_ATOMIC_WRITE] compile-time option. |
