Abstract
An aspect includes splitting a table of buckets into a fixed number of domains. Each of the domains includes a corresponding subset of the buckets. An aspect also includes providing a spare bucket for each of the subsets of the buckets and providing a metadata structure for each of the domains. The metadata structure includes a head pointer that points to a first bucket of a corresponding subset of the buckets and a spare_bucket pointer that points to the spare bucket of the subset of the buckets. An aspect further includes providing a split-spare bucket pointer that interleaves, during updates to data, among the subset of buckets in the domain. Data subject to the updates is stored in the spare bucket for a corresponding one of the domains. An aspect also includes updating the head pointer and the spare_bucket pointer for corresponding domains in response to updating the data.
