+# Parquet Example Data
+
+Parquet data can be stored in many different ways - with or without metadata, in key-value partitioned directories, or in flat partitioned directories. This directory contains a simple dataset stored in all of these different formats. These are used to demonstrate Deephaven's ability to read various kinds of Parquet data.
+
+
+## The `grades` dataset
+
+The `grades` dataset is a simple synthetic dataset used to demonstrate the various ways to store Parquet data. It looks like this:
+
+| Name   | Class   | Test1 | Test2 |
+| ------ | ------- | ----- | ----- |
+| Ashley | Math    | 92    | 94    |
+| Jeff   | Math    | 78    | 88    |
+| Rita   | Math    | 87    | 81    |
+| Zach   | Math    | 74    | 70    |
+| Ashley | Science | 87    | 91    |
+| Jeff   | Science | 90    | 83    |
+| Rita   | Science | 99    | 95    |
+| Zach   | Science | 80    | 78    |
+| Ashley | History | 82    | 88    |
+| Jeff   | History | 87    | 92    |
+| Rita   | History | 84    | 85    |
+| Zach   | History | 76    | 78    |
+
+This dataset can be partitioned by `Name` or `Class` to demonstrate the different ways to store Parquet data.
