I faced a weird issue: the same qryn with the same query returns a different log volume value depending on whether I specified or not json parser. Here is a screenshot:
My current deployment:
Clickhouse 3 shards with 2 replicas -> chproxy (1 instance) -> qryn (1 instance)
I've tried to remove chproxy, but got the same result - different log volume value.
In the qryn logs I see below:
for query with json parser:
WITH sel_a AS (select `samples`.`string` as `string`,`samples`.`fingerprint` as `fingerprint`,samples.timestamp_ns as `timestamp_ns`,JSONExtractKeysAndValues(time_series.labels, 'String') as `labels` from cloki.samples_v3_dist as `samples` left any join `cloki`.`time_series` AS time_series on `samples`.`fingerprint` = time_series.fingerprint where (`samples`.`timestamp_ns` between 1697222530351000000 and 1697308930351000000) and (samples.fingerprint IN (select `sel_1`.`fingerprint` from (select `fingerprint` from `cloki`.`time_series_gin` where ((`key` = 'Product') and (`val` = 'Platform'))) as `sel_1` inner any join (select `fingerprint` from `cloki`.`time_series_gin` where ((`key` = 'service') and (`val` = 'platform-users-service'))) as `sel_2` on `sel_1`.`fingerprint` = `sel_2`.`fingerprint`)) order by `timestamp_ns` desc limit 1000) select * from sel_a order by `labels` desc,`timestamp_ns` desc
for query without json parser:
