 # NovaLSM
-Nova-LSM is a component-based design of the LSM-tree using fast and high bandwidth networks such as RDMA. These components implement the following novel concepts.  First, they use RDMA to enable nodes of a shared-nothing architecture to share their disk bandwidth and space. Second, they construct ranges dynamically at runtime to boost performance and parallelize compaction. Third, they scatter blocks of a file (SSTable) across an arbitrary number of disks to scale. Fourth, the logging component separates availability of log records from their durability.  These designs provide for alternative implementations of a component with different configuration settings.  We present an implementation of these designs using LevelDB.  Our evaluation shows Nova-LSM scales and outperforms its monolithic counter-part by several orders of magnitude.

 # Platform
 Linux. We have tested it on [CloudLab R320 and R6220](https://docs.cloudlab.us/hardware.html) instances.
