Struct Commit 

pub struct Commit {
    pub version: u64,
    pub base_version: u64,
    pub timestamp: DateTime<Utc>,
    pub actions: Vec<LogAction>,
}

A single, immutable commit in the metadata log.

Commits are written to files such as _timeseries_log/0000000001.json. The version field must match the file name; base_version records what the writer believed was the current version when the commit was prepared.

Fields

version: u64

The version number of this commit (monotonic, starting from 1).

base_version: u64

The version that the writer believed was current when preparing this commit. Used by the OCC layer as a guard.

timestamp: DateTime<Utc>

Commit creation timestamp, stored as RFC3339 UTC.

actions: Vec<LogAction>

Ordered list of actions that describe how table state changes in this commit.
