CatalogManifestStore

laminar_core::cluster::control::catalog_manifest

Struct CatalogManifestStore 

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

I/O wrapper for the CatalogManifest on an object store.

Implementations§

Source§

impl CatalogManifestStore

Source

pub fn new(store: Arc<dyn ObjectStore>) -> Self

Wrap a pre-constructed object store.

Source

pub async fn load( &self, ) -> Result<Option<CatalogManifest>, CatalogManifestError>

Load the current catalog manifest; Ok(None) on a fresh cluster.

§Errors

Object-store I/O or JSON decode failure.

Source

pub async fn save( &self, manifest: &CatalogManifest, ) -> Result<(), CatalogManifestError>

Overwrite the catalog manifest. Last writer wins — the leader (or any node executing catalog DDL) publishes the latest full catalog.

§Errors

Object-store I/O or JSON encode failure.
