Influxdb2 is too slow on query any data!

write data to influxdb2 is very fast, but read too slow until the influxd.exe crashed. i just read limit 100 data from my meansure,why? how can i do next

Short answer, influxdb3 was created partly to solve the challenges with querying data that is faced with v2.

Influxdb 3 is hopefully just around the corner now.

If you have a specific question with why a query is slow or using a lot of memory, ask away.
