PublishMetadata

delta_kernel::committer

Struct PublishMetadata 

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

Metadata required for publishing catalog commits to the Delta log.

PublishMetadata bundles all the information needed to publish catalog commits: the version up to which commits should be published, and the list of catalog commits themselves.

§Invariants

The following invariants are enforced at construction time:

  • commits_to_publish must be non-empty
  • commits_to_publish must be contiguous (no version gaps) in ascending order of version
  • The last catalog commit version must equal publish_to_version

See Committer::publish for details on the publish operation.

Implementations§

Source§

impl PublishMetadata

Source

pub fn try_new( publish_to_version: Version, commits_to_publish: Vec<CatalogCommit>, ) -> DeltaResult<Self>

Creates a new PublishMetadata with the given publish to version and catalog commits.

Source

pub fn publish_version(&self) -> Version

The snapshot version up to which all catalog commits must be published.

Source

pub fn commits_to_publish(&self) -> &[CatalogCommit]

The list of contiguous catalog commits to be published, in ascending order of version.
