The part of InfluxDB's data structure that describes for how long InfluxDB keeps data (duration), how many copies of this data is stored in the cluster (replication factor), and the time range covered by shard groups (shard group duration). CREATE RETENTION POLICY "week" ON "graphite" DURATION 7d REPLICATION 1. InfluxDB stores the results of the CQ in a specified measurement. One of the first places to begin comparing QuestDB and InfluxDB is how data is handled and stored in each database. xts and zoo are libraries for working with time series data, influxdbr is the library for connecting with InfluxDB databases .

Congratulations on spinning up InfluxDB 2.0. tsm1 Indexes: Using tsm1 index (available from 2016 releases) instead of memory indexes will pave way to store high cardinality values. InfluxDB is an open-source time series database developed by InfluxData. We're going to use its retention policies and continuous queries to automatically aggregate and expire the ingested metering data in order to built an efficient Smart Metering dashboard.
