It is difficult to decide which system is right for your application, partially because the features differ between
|
|
systems, and partially because there is not an easy way to compare the performance of one system versus another.
|
|
<P>
|
|
The goal of the YCSB project is to develop a framework and common set of workloads for evaluating the performance of
|
|
different "key-value" and "cloud" serving stores. The project comprises two things:
|
|
<ul>
|
|
<LI>The YCSB Client, an extensible workload generator
|
|
<LI>The Core workloads, a set of workload scenarios to be executed by the generator
|
|
</UL>
|
|
Although the core workloads provide a well rounded picture of a system's performance, the Client is extensible so that
|
|
you can define new and different workloads to examine system aspects, or application scenarios, not adequately covered by
|
|
the core workload. Similarly, the Client is extensible to support benchmarking different databases. Although we include
|
|
sample code for benchmarking HBase and Cassandra, it is straightforward to write a new interface layer to benchmark
|
|
your favorite database.
|
|
<P>
|
|
A common use of the tool is to benchmark multiple systems and compare them. For example, you can install multiple systems
|
|
on the same hardward configuration, and run the same workloads against each system. Then you can plot the performance
|
|
of each system (for example, as latency versus throughput curves) to see when one system does better than another.

YCSB is designed to be extensible. It is easy to add a new database interface layer to support benchmarking a new database. It is also easy to define new workloads.
