Storing and Querying Tree-Structured Records in Dremel
Summary: Formal data model and query language for tree-structured records in Dremel (nested relations, leaf-valued attributes, repeated attributes). Columnar processing of Dremel's filter/aggregate queries via repetition context and semi-flattening achieves linear-time complexity in the size of relevant data.
