Jihoon Son commented on TAJO-835:
---------------------------------
Hi [~hyunsik],
I thought about your comment more deeply, and realized that I missed some of
your points.
For 3), did you mean that we need to provide an way of specifying the index
location like the LOCATION clause of CREATE EXTERNAL TABLE statement? If so, I
totally agree on that.

> Key: TAJO-835
> URL: https://issues.apache.org/jira/browse/TAJO-835
> Project: Tajo
> Issue Type: New Feature
> Reporter: Jihoon Son
> Priority: Minor
>
> Indexes are widely used to reduce I/O overhead in databases.
> In Tajo, some index structures such as BST are already implemented, but their
> usages are very limited. Currently, only BST is used for range partition.
> The better utilization of indexes can improve the query performance.
