Is there a way to update the value by time?
I search again and can see some results says I have to delete the data and insert again.
insert example,a=1,b=3,c=4 value=“x=1;y=2;z=3” time=1111111111111111
if I need to change the “a” or “value”,
I will have to
delete example where time=11111111111111111
insert example,a=2,b=4,c=5value=“x=1;y=2;z=3” time=1111111111111111
is that high efficiency in realtime updates?
thanks e-dard my requiments is
receiving some realtime data of finance stocks. as you know. every raw data is in form of miliseconds and I don’t want to save it to database as its too big when I always receive it. so I have to conbine them to 1 minutes data. so the time format is “minute”,not “seconds” or “miliseconds” or “nanoseconds” for me. if I can update the data by “minute”, then I decouple the usage of keep the last minute on my memory.
If you are updating the TAG value it will result in a newer log entry or newer database entry. If you are updating a field value; it will only update the field value (or the entry will be overwritten with newer values).
Seems like based on your requirement you are looking at updating both TAG and FIELD values. Check if you are make schema changes so only fields are updated.
