4 years ago We tested Chronix with 2 cores....here is comments from one of my colleagues; (This is an old log)
Test Multicore basics
Created 2 cores - chronix & chronix_new (same as chronix)
Store data in both cores by /update to each core with chronological data without batching - Stored 2 timeseries each into chronix & chronix_new (metrics with same name but with different points)
Perform chronix/solr query with shards parameter: I got couple of errors
NullPointerException - Due to unique key is not set. Currently we have commented out the “id ”. To shards to work this must be needed. I uncommentout it. This resolve this error.
Conflict version - Solr expects the “version“ field to not set explicitly by our code when unique key is configured in schema. This is resolved by not setting “version” field from code.
ParseException - Could not parse date representation '[1567776032526' - Still debugging it. When I query from one core (without shards param), it returns metrics from that core only. It looks like while using shards the chronix server code not properly parsing the date param (_name:container_memory_utilizationc AND start:NOW-24HOURS AND end:NOW) properly. However When I query without time filter (name:container_memory_utilization_c) it returns metrics from both cores.
The ParseException Trace is as follows:

If we load data into 2 cores, the inserts go thru fine.
If we query any one core at a time, the data comes thru fine.
But if we specific more than one core in the query, the query fails.
There is a time format error.
