빌드 테이블

drop table iotjetsonjson ON CLUSTER '{cluster}';
drop table iotjetsonjson_local ON CLUSTER '{cluster}';

CREATE TABLE iotjetsonjson_local
(
    uuid String, 
    camera String,
    ipaddress String,  
    networktime String, 
        top1pct String, 
    top1 String, 
    cputemp String, 
    gputemp String,
        gputempf String,
    cputempf String, 
    runtime String,
    host String,
    filename String,  
    host_name String, 
        macaddress String, 
    te String, 
    systemtime String,
    cpu String,
        diskusage String,
    memory String, 
    imageinput String
)
ENGINE = MergeTree()
  PARTITION BY uuid
  ORDER BY (uuid);


CREATE TABLE iotjetsonjson ON CLUSTER '{cluster}' AS iotjetsonjson_local
ENGINE = Distributed('{cluster}', default, iotjetsonjson_local, rand());

쿼리

select uuid, top1pct, top1, gputempf, cputempf
from iotjetsonjson
where toFloat32OrZero(top1pct) > 40
order by toFloat32OrZero(top1pct) desc, systemtime desc


select uuid, systemtime, networktime, te, top1pct, top1, cputempf, gputempf, cpu, diskusage, memory,filename
from iotjetsonjson 
order by systemtime desc
