Indexing HDFS Data in PDW: Splitting the data from the index
Summary: Proposes using B+-tree indices in an RDBMS to access data stored in HDFS, effectively splitting storage from indexing. Demonstrates that the PDW-driven approach yields efficient, highly selective query processing by exploiting RDBMS indexing on Hadoop data. (summarized by gpt-5-nano on Feb 09 2026)
