influxdb查询这么慢，如何提高性能

Question

I use the influxdb java api to query records from influxdb and found the performance not good have set the query fields to tag below is the sql and execution time in java anybody know how to change or do sth for the query performance thx!

> select count(*) from propRecords where devId='1000000005020009' and propKey='B_phs_V' and time >=1583424000000000000 and time <=1584028800000000000

        name: propRecords
        time                count_cmd count_propValue
        ----                --------- ---------------
        1583424000000000000 269632    269632

use below influx api to query:

InfluxDB.class

public QueryResult query(Query query) {
    return this.executeQuery(this.callQuery(query));
}

Not sure how invested you are in InfluxDB, but the performance of QuestDB is a lot better. https://questdb.io/ It supports full SQL for queries. I've been running queries against the 1.6B row NYC Taxi dataset and getting sub-second results on a sum() over all 1.6B rows.
