Hi,
I have a problem with queries like
select var1,var2 from measure1 where time >= '2015-03-01' Limit 4
where the field var1 was added before the field var2 to the database. Influx
returns e.g.
measure1
time var1 var2
2015-03-01T00:00:00Z 3908
2015-03-01T00:00:00Z 3
2015-03-01T00:00:02Z 3794
2015-03-01T00:00:02Z 3
but I expected that there is an automatic join on the timestamp and influx
response looks like
measure1
time var1 var2
2015-03-01T00:00:00Z 3908 3
2015-03-01T00:00:02Z 3794 3
If I add another field var3 then the influx partly joins the series
measure1
time var1 var2 var3
2015-03-01T00:00:00Z 3908
2015-03-01T00:00:00Z 3 2
2015-03-01T00:00:02Z 3794
2015-03-01T00:00:02Z 3 1
I added the data via the DataFrameClient from the python influx library:
db.write_points(df, 'measure1', batch_size=1000)
where df is a pandas DataFrame containing the column var1.
And for the fields added afterwards:
db.write_points(pd.DataFrame(data={'var2': 3}, index=df.index), 'measure1',
batch_size=50000)
where df is again a pandas DataFrame which results from a influxdb query for
var1 in measure1.
Am I doing something wrong and is this behavior as expected? Then how is it
possible to merge the series?
I was using the version 1.0 of influxdb and updated to the current version on
github a few days ago (same behavior).
Thanks in advance!
Best regards,
Marc
