| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | MapReduce-based processing infrastructure is getting more important as a data analysis system,which executes ad-hoc queries, in addition to regular batch queries.In MapReduce environment, each map task scans all records and processes them.This all-scan access is repeated if similar queries is repeatedly issued - for example the queries which have the range condition on the same column. In this paper, in order to process efficiently ad-hoc but with-similar-range-condition query in Map Reduce environment, we will consider the introduction of adaptive indexing techniques into Map Reduce environment. Adaptive indexing is a DBMS technique \ddash index creation and update during the query execution.Every query, index is updated so that subsequent queries will take shorter execution time by using this improved index.We will discuss the challenge around the adaptation of the adaptive indexing into MapReduce environment and propose some model. |
