Hyunsik Choi commented on TAJO-835:
-----------------------------------

Hi Jihoon,

I have two questions. 1) Will you put the completed indexing feature to 0.9.0? 
2) Do you have any plan to implement a different index structure other than 
BSTIndex?

> 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.
