Release 0.8.0

QuantumLeap version 0.8.0highlights:

• Experimental support to store NGSI-LD payloads: The notify API endpoint now accepts both NGSI-LD and NGSI-v2 entities! While there are still some limitations to what NGSI-LD payloads QuantumLeap can process, the most common scenarios should be covered.
• Much improved data ingestion (notify API endpoint) performance with a brand new Redis query cache.
• Full support for Timescale: The Timescale backend is now on par, in terms of features, with the CrateDB backend---i.e. all API endpoints work both with Timescale and CrateDB. Running both backends side-by-side is also supported---e.g. routing data to a specific DB depending on tenant.
• Gunicorn support: You can now run QuantumLeap as a WSGI app in your own Gunicorn server or even start QuantumLeap with its own embedded Gunicorn instance.
• Ability to collect telemetry time-series for performance analysis---turn on telemetry then use e.g. Pandas to analyse your data.
• Better logs and documentation as well as a number of critical bug fixes.

See #434 for the details. We recommend QuantumLeap 0.7.6 users to upgrade to this version.

0.8-alpha

New features:

• gunicorn as web server
• implement basic redis cache for metadata (reducing number of queries to database)
• provide a reusable connection to database (nor crate driver or pg8000 seems to support pool natively)
• improve logs and use orion like format
• add support for fiware-correlator (facilitate tracking data chains between agents, orion and quantumleap)
• fix postgres issue in travis tests
• split create table from update table logic
• use alter table for adding column to crate
• change crate table column_policy from dynamic to strict
• support injection of NGSI-LD payloads in NGSI-V2 backcompatible way
• when type is not an NGSI type, it's type is derived from value (support #383)
• query api support for timescaledb (#374)
• Improve crate 4.x support (#370)
• update docs

Bugs:

• support mismatch between DateTime (as medatata) and column type (#386)
• fix date format to be compatible also with crate 3.x (#353)
• support for different servicepath when multiple notifications arrive at once (#208)
• issues with programmatic delete (#347)

Release 0.7.6

This release (0.7.6) is a stepping stone to 0.8 and comes with most of the features planned for 0.8. However, there still are some rough edges so 0.7.5 remains our latest stable.

New features, bug fixes and backward compatibility of this release are documented by PR #275 and also detailed in the release notes. As usual, you can pull a Docker image for this release from DockerHub.

Bump to 0.7.5 (#251)

* Bump to 0.7.5

• Optimised docker image, size is now down to 170 MB (#116)
• Support for missing entity attributes (#122)
• Metadata query fixes (#115)
