+YCSB
+====================================
+[![Build Status](https://travis-ci.org/brianfrankcooper/YCSB.png?branch=master)](https://travis-ci.org/brianfrankcooper/YCSB)
+
+
+
+Links
+-----
+* To get here, use https://ycsb.site
+* [Our project docs](https://github.com/brianfrankcooper/YCSB/wiki)
+* [The original announcement from Yahoo!](https://labs.yahoo.com/news/yahoo-cloud-serving-benchmark/)
+
+Getting Started
+---------------
+
+1. Download the [latest release of YCSB](https://github.com/brianfrankcooper/YCSB/releases/latest):
+
+    ```sh
+    curl -O --location https://github.com/brianfrankcooper/YCSB/releases/download/0.17.0/ycsb-0.17.0.tar.gz
+    tar xfvz ycsb-0.17.0.tar.gz
+    cd ycsb-0.17.0
+    ```
+    
+2. Set up a database to benchmark. There is a README file under each binding 
+   directory.
+
+3. Run YCSB command. 
+
+    On Linux:
+    ```sh
+    bin/ycsb.sh load basic -P workloads/workloada
+    bin/ycsb.sh run basic -P workloads/workloada
+    ```
+
+    On Windows:
+    ```bat
+    bin/ycsb.bat load basic -P workloads\workloada
+    bin/ycsb.bat run basic -P workloads\workloada
+    ```
+
+  Running the `ycsb` command without any argument will print the usage. 
+   
+  See https://github.com/brianfrankcooper/YCSB/wiki/Running-a-Workload
+  for a detailed documentation on how to run a workload.
+
+  See https://github.com/brianfrankcooper/YCSB/wiki/Core-Properties for 
+  the list of available workload properties.
+
+
+Building from source
+--------------------
+
+YCSB requires the use of Maven 3; if you use Maven 2, you may see [errors
+such as these](https://github.com/brianfrankcooper/YCSB/issues/406).
+
+To build the full distribution, with all database bindings:
+
+    mvn clean package
+
+To build a single database binding:
+
+    mvn -pl site.ycsb:mongodb-binding -am clean package

+# Apache Cassandra 2.x CQL binding
+
+Binding for [Apache Cassandra](http://cassandra.apache.org), using the CQL API
+via the [DataStax
+driver](http://docs.datastax.com/en/developer/java-driver/2.1/java-driver/whatsNew2.html).
+
+To run against the (deprecated) Cassandra Thrift API, use the `cassandra-10` binding.
+
+## Creating a table for use with YCSB
+
+For keyspace `ycsb`, table `usertable`:
+
+    cqlsh> create keyspace ycsb
+        WITH REPLICATION = {'class' : 'SimpleStrategy', 'replication_factor': 3 };
+    cqlsh> USE ycsb;
+    cqlsh> create table usertable (
+        y_id varchar primary key,
+        field0 varchar,
+        field1 varchar,
+        field2 varchar,
+        field3 varchar,
+        field4 varchar,
+        field5 varchar,
+        field6 varchar,
+        field7 varchar,
+        field8 varchar,
+        field9 varchar);
+
+**Note that `replication_factor` and consistency levels (below) will affect performance.**
+
