Hi, I'm trying to insert timeseries data to HBase using Phoenix 4.4.0, I would need a row per device per day. I'm capturing data from devices every minute. So in a row per day 1440 records (columns) has to be stored. I have designed a schema as follows: create table devicedata (deviceId integer not null, day date not null, ts timestamp, val double CONSTRAINT my_pk PRIMARY KEY (deviceId, day)); But when I use upsert, it updates the values and in a row, I always have only the last value of the day. Help me design a schema using phoenix, to store continuous device data. My data is going to be huge and performance is my first concern.
