Examples of RowKeySchema

com.salesforce.phoenix.schema.RowKeySchema
Schema for the bytes in a RowKey. For the RowKey, we use a null byte to terminate a variable length type, while for KeyValue bytes we write the length of the var char preceding the value. We can't do that for a RowKey because it would affect the sort order. @author jtaylor @since 0.1
