Type Aliasesยง

  • A durable store of the catalog state using Persist as an implementation. The durable store can serve any catalog data and transactionally modify catalog data.
  • Timestamp ๐Ÿ”’
    New-type used to represent timestamps in persist.
  • A Handle to an unopened catalog stored in persist. The unopened catalog can serve Config data, Setting data, or the current epoch. All other catalog data may be un-migrated and should not be read until the catalog has been opened. The UnopenedPersistCatalogState is responsible for opening the catalog, see OpenableDurableCatalogState::open for more details.
