> I am working with timeseries and I would like to extract all the values for a sensor (12M row for one year). I thought it would work with Phoenix as it would stream the result but it seems it can't.
> My table is as follows:
> |M|	VARCHAR	|13|
> |TS|	TIMESTAMP	|-|
> |V|	FLOAT	|-|
> |Q|	CHAR	|10|
> |N|	VARCHAR	|10|
> The code giving the exception:
> {code}
> final ResultSet rs = statement.executeQuery(
> 				"SELECT m, ts, v FROM myTable WHERE m = 'mySensor'");
> while (rs.next()) {
> 	final String line = rs.getString(1) + "," + rs.getDate(2).getTime() + "," +  rs.getFloat(3);
> 	ps.println(line);
> }
> {code}
> After a while I got the following stacktrace:
> {code}
> Exception in thread "main" org.apache.phoenix.exception.PhoenixIOException: org.apache.phoenix.iterate.SpoolTooBigToDiskException: result too big, max allowed(bytes): 1044971520
