Enum CommitPolicy

pub enum CommitPolicy {
    SyncFlush = 0,
    Buffered = 1,
    Delayed = 2,
    NoSync = 3,
}

Transaction commit policy.

The default policy is SyncFlush.

Variants

SyncFlush = 0

Flush the cache and synchronize the filesystem buffers for both database and log files on every commit.

Buffered = 1

Don’t flush the database cache to disk upon transaction commit.

Delayed = 2

Keep modified pages in the page pool (like Buffered); commit delayed transactions to the persistent storage at once when the total size of all kept pages or the number of delayed commits reach a threshold value.

NoSync = 3

Don’t synchronize the file system buffers explicitly and let the filesystem determine when the data is actually written to the media.
