Overview
InfluxDB is a time series DBMS.
InfluxDB supports a text format of query plans, and does not explicitly show operations being performed in query plans, so we examined properties only.
Example
insert cpu,host=node1 value=10
Text format of the query plan
explain select * from cpu
The query plan includes a list of key-value pairs, in which keys are property names and values are property values.
