 # MySQL Data Redistribution
+
+## Motivation
+While B-Tree is a ubiquitous index structure used in managing data, it is well known for its low space utilization in nodes. Such space under-utilization is detrimental to flash storage in terms of cost and performance. In particular, the logical space waste in B-tree will amplify physical writes inside flash storage, worsening the transaction throughput.
+
+## Contribution
+Our evaluation results from running OLTP benchmarks using the optimized MySQL/InnoDB prototype clearly show that those optimizations improve transaction throughput (i.e., more than 50%) with less space and cost (i.e., less than 40%) in flash storage.
+
+## Prerequisites & Installation Guide
+
+1. Install prerequisites of mysql-5.6.26. Follow the instructions in the [site](https://github.com/LeeBohyun/mysql-tpcc/blob/master/installation_guide/multi-mysql-tpcc.md).
+2. Clone this repository.
+```bash
+$ git clone https://github.com/FlashSQL/MySQL-Data-Redistribution.git
+```
+3. Run ``mysqld`` server to run MySQL.
