Abstract
Example implementations disclosed herein can be used to build, maintain, and use a hash table distributed across the plurality multiple nodes in a multi-node computing system. The hash table can include data pages associated by corresponding pointers according to a tree data structure. The data pages include leaf data pages. Each leaf data page can be associated with a corresponding hash value and include a tag bitmap. When a transaction associated with a key is executed, a hash value and a tag value are generated based on the key. The leaf data pages can be searched using the hash value. A probability that a leaf data page includes the key can be determined based on a comparison tag value with the tag bitmap.
