This is useful in modern cloud platforms which are not only huge

but also are dynamic and potentially multi-tenant.

Gnocchi takes all of that into account._

|

_Time Series Databases have to deal with specific workloads and requirements.
|
||||
They need to ingest millions of data points per second; to perform real-time
|
||||
queries across these large data sets in a non-blocking manner; to downsample
|
||||
and evict high-precision low-value data; to optimize data storage to reduce
|
||||
storage costs; and to perform complex time-bound queries to extract meaningful
|
||||
insight from the data. It is possible to meet these requirements only with a
|
||||
purpose-built platform that InfluxData provides._

# On essaye ?
|

|

Ok, c'est parti. Premier souci, la documentation est assez légère.
|
||||
|
||||
|
||||
On va tenter d'écrire un injecteur en Perl. Puis enchainer sur
|
||||
une visualisation dynamique des données en lancer de rayon.
|
||||
Projet ambitieux ? Non, la suite sera bien pire.
