How much data can a single InfluxDB hold?

Is there any limit to the amount of data that can be stored in InfluxDB?

There are no systemic limits to the amount of data an individual instance can hold. Also the storage engine is very efficient (3 bytes per float or integer value). Data is naturally sharded by time so old data is not touched on most queries. There are InfluxDB users with TBs of data in a single instance.
