Hi,I just noticed something when i am playing with examples. Class.forName("org.apache.calcite.jdbc.Driver")val properties: Properties = new Properties() properties.setProperty("caseSensitive","true") val connection = DriverManager.getConnection("jdbc:calcite:", properties) val calciteConnection=connection.unwrap(classOf[CalciteConnection])val schema= (new CsvSchemaFactory()).create(calciteConnection.getRootSchema,null,Map[String,AnyRef]("directory" -> "src/main/resources/csv","flavor" -> "scannable").asJava)calciteConnection.getRootSchema.add("TEST",schema)val statement2=calciteConnection.prepareStatement("select \"tarih\" from \"TEST\".\"timeseries\" where \"sensor\" = ?")statement2.setString(1,"sensor38")val resultSet1=statement2.executeQuery() while(resultSet1.next()) println(resultSet1.getString("tarih"))My example like above. But when i call executeQuery i noticed that CsvScannableTable.scan called twice and enumerator iterating on values. When i inspected stacktraces i found that one of the call come from AvaticaConnection.java:463 and the other one is AvaticaConnection:481 . Is this a normal behaviour or bug?
Can you share what version of Calcite you are using, please?
