Index (Experimental Feature)ΒΆ

An index is a data structure that is used for efficient query processing. Using an index, the Tajo query engine can directly retrieve search values.

This is still an experimental feature. In order to use indexes, you must check out the source code of the index_support branch:

git clone -b index_support tajo-index

For the source code build, please refer to Getting Started.

The following sections describe the supported index types, the query execution with an index, and the future works.
