An error is reported when the amount of data is too large

An error is reported when the amount of data is too large
It is normal to test 200 million data of the same code for dozens of times, and 500 million data will report an error
The code is as follows：
public static void addDataToTable() {
try
{

	    	 Properties ro_prop = new Properties();
				ro_prop.setProperty("duckdb.read_only", "False");
			DuckDBConnection conn2=null;
			  try {
					conn2 = (DuckDBConnection) DriverManager.getConnection("jdbc:duckdb:C:\\test\\duckdb\\test.db");
				} catch (SQLException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			Statement stmt = conn2.createStatement();
			
			stmt.execute("CREATE TABLE data2 (n_id VARCHAR, vendor_id VARCHAR, pickup_at VARCHAR,dropoff_at VARCHAR,passenger_count VARCHAR,trip_distance VARCHAR,rate_code_id VARCHAR,store_and_fwd_flag VARCHAR,pickup_location_id VARCHAR,dropoff_location_id VARCHAR,payment_type VARCHAR,fare_amount VARCHAR,extra VARCHAR,mta_tax VARCHAR,tip_amount VARCHAR,tolls_amount VARCHAR,improvement_surcharge VARCHAR,total_amount FLOAT,congestion_surcharge FLOAT)");
			DuckDBAppender appender = conn2.createAppender("main", "test");
		
			conn2.setAutoCommit(false);
			
			stmt.execute("START TRANSACTION");
	     
	    	  for(int rowIndex=0;rowIndex<500000000;rowIndex++) {
	    		  
		    	  appender.beginRow();
		    	  appender.append("n"+rowIndex);
		    	  for(int i=1;i<=16;i++) {
		    		 
		    			  appender.append("str_"+rowIndex);
		    		  
		    	  }
		    	  appender.append(1F);
		    	  appender.append(rowIndex);
		    	  appender.endRow();
		    	  
		    	  if(rowIndex%(1024000*2)==0) {
		    		  stmt.execute("COMMIT");
		    		  stmt.execute("START TRANSACTION");
		    		 
		    	  }
		      
	    	  }
	      
	    	  appender.close();
		      stmt.execute("COMMIT");
	      stmt.close();
	      conn2.close();
	    }catch(Exception e) {
	    	e.printStackTrace();
	    }

}

The query code is as follows:

public static void main(String[] args) {
System.out.println("++++++++++++++");
String sql1="SELECT * FROM test";
queryTest(sql1);

}
public static int queryTest(String sql) {

try
{
Properties ro_prop = new Properties();
ro_prop.setProperty("duckdb.read_only", "false");
DuckDBConnection conn = (DuckDBConnection) DriverManager.getConnection("jdbc:duckdb:C:\test\duckdb\test.db");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(sql);
rs.close();
stmt.close();
conn.close();

}catch(Exception e) {
e.printStackTrace();
}

return count;
}

There is no problem when this code generates 200 million pieces of data, but there is a problem when it increases to 500 million

java.sql.SQLException: Catalog Error: Table with name test does not exist!
LINE 1: SELECT * FROM test
