Abstract
In at least one embodiment, processing can include: storing a metadata page at new physical location PA2 on non-volatile storage; and recording in a translation table (TT) log, a TT update to a mapping entry E1 of the TT, wherein the TT update updates E1 of the TT to map a logical address LA1 of the metadata page to PA2. Recording can include querying a unified hash table (UHT) in accordance with LA1 to determine whether the UHT includes a UHT entry mapping LA1 to a corresponding physical address or location of where the MD page is stored on non-volatile storage. Responsive to determining that the UHT includes a UHT entry for LA1, processing can include: determining whether the UHT entry is a cache type. If the UHT entry is the cache type, processing can include converting the UHT entry to a delta type entry of the TT log.
