QuantumLeap is the first implementation of an API that supports the storage of FIWARE NGSIv2 data into a time series database. It currently also experimentally supports the injection of NGSI-LD in a backward compatible way with NGSI-v2 API. I.e. you can retrieve NGSI-LD stored data via NGSI v2 API and retrieve data will be describe following NGSI v2 format.
QuantumLeap is not a real time API, its purpose is to process notifications received from the Context Broker and to create temporal records for them. In general, the whole FIWARE stack, being based on a micro-service architecture, cannot be regarded as real time in case you have requirements on guaranteed delivery in a given amount of time.
However, even though hard real time may not be FIWARE's forte, in our experience a properly tuned FIWARE stack can perform extremely well and handle very demanding IoT workloads without a glitch - you just need to configure your infrastructure to handle that :)

QuantumLeap supports both Crate DB and Timescale as time-series DB backends but please bear in mind that at the moment we only support the following versions:
- Crate backend: Crate DB version
- Timescale backend: Postgres version
11.*+ Timescale extension
1.3.*+ Postgis extension
Refer to the User Manual.
Refer to the Troubleshooting section.
The following is a collection of external guides and pages where you may find additional documentation about QuantumLeap. Note that these guides could be outdated (so could the official docs!), so we appreciate all efforts to keep consistency.
