Abstract

In at least one embodiment, processing can include: receiving, at a first node, a read operation that reads content of a logical address, wherein a second node, but not the first node, owns the logical address; and performing optimized read processing for the read operation. The optimized read processing can include: performing, in parallel, first processing that obtains a first address hint and first content corresponding to the logical address, and second processing that obtains a second address hint corresponding to the logical address; determining whether the first and second address hints match; if the first and second address hints match, determining that first content is valid content stored at the target logical address; if the first and second address hints do not match, determining the first content is not stored at the logical address, and using the second address hint to obtain second content stored at the logical address.
