Memory Buffer Data Source

Introduction

When data is accessed through data source, it is fetched from the original data source. This approach is often the only feasible one due to size of data sets.

In some applications, especially in SOM vizualization, input data is accessed many times. If data set is not too large, by buffering data into memory, processing can be speeded up considerably.

Setup

Buffering can be achieved by introducing <memorybuffer> data source:

<som>
   <memorybuffer>
      <csv source="..."/>
   </memorybuffer>
</som>
