A database system receives a request to access one of a plurality of data containers. Such request includes a file identification (ID) corresponding to the requested data container. Using this file ID, metadata associated with the requested data container is accessed. The metadata is stored in a page of page chain and such metadata identifies a location of the requested data container (so that it can be accessed). Thereafter, the metadata is used to enable access to the requested data container. The file ID in the request can encapsulate a page number and at least one index. This page number identifies a page in the page chain storing the metadata and the index identifies a location within the identified page where the metadata can be found. Related apparatus, systems, techniques and articles are also described.
