Abstract
In at least one embodiment, processing can include receiving a metadata (MD) structure including MD pages; and performing a MD split operation with respect to a first of the MD pages, wherein said performing the MD split operation includes: generating a first ALI (abstract logical index) representing a new MD page that is unallocated and is a child of the first MD page; and storing an entry in a bucket of an in-memory MD log for the first ALI, wherein the entry denotes a mapping between the first ALI and a corresponding LI (logical index), wherein the entry indicates that the corresponding LI associated with the first ALI is invalid since the first ALI represents a new MD page which is unallocated and not associated with physical storage; and destaging the in-memory MD log, wherein said destaging includes allocating first physical storage for the new MD page.
