CommitMetadata

delta_kernel::committer

Struct CommitMetadata 

Source 
pub struct CommitMetadata { /* private fields */ }
Expand description

CommitMetadata bundles the metadata about a commit operation. This currently includes the commit path and version but will expand to things like Protocol, Metadata, etc. to allow for catalogs to understand/cache/persist more information about the table at commit time.

Note that this struct cannot be constructed. It is handed to the Committer (in the commit method) by the kernel when a transaction is being committed.

See the module-level documentation for more details.

Implementations§

Source§

impl CommitMetadata

Source

pub fn published_commit_path(&self) -> DeltaResult<Url>

The commit path is the absolute path (e.g. s3://bucket/table/_delta_log/{version}.json) to the published delta file for this commit.

Source

pub fn staged_commit_path(&self) -> DeltaResult<Url>

The staged commit path is the absolute path (e.g. s3://bucket/table/_delta_log/{version}.{uuid}.json) to the staged commit file.

Source

pub fn version(&self) -> Version

The version to which the transaction is being committed.

Source

pub fn in_commit_timestamp(&self) -> i64

The in-commit timestamp for the commit. Note that this may differ from the actual commit file modification time.

Source

pub fn table_root(&self) -> &Url
