Bonjour, pour la mise en place d'une solution de suavegarde se basant sur rollover et la notion j'ai voulu testé le cas expliqué dans le lien suivant:
> **[And the big one said "Rollover" — Managing Elasticsearch time-based indices...](https://www.elastic.co/blog/managing-time-based-indices-efficiently)**
>
> Introducing the new Rollover Pattern, and the APIs which support it, which is a simpler, more efficient way of managing time-based indices in Elasticsearch.
Je suis bloqué à la commande suivante:
curl -XPOST [http://node2:9200/active-logs/\_rollover](http://node2:9200/active-logs/_rollover) -d '
{
"conditions": {
"max\_age": "7d",
"max\_docs": 5
}
}'
Voilà le message d'erreur obtenu:
{"error":{"root\_cause":[{"type":"invalid\_index\_name\_exception","reason":"Invalid index name [_rollover], must not start with '_'","index":"\_rollover"}],"type":"invalid\_index\_name\_exception","reason":"Invalid index name [_rollover], must not start with '_'","index":"\_rollover"},"status":400}
J'ai l'impression que elasticsearch (2.3.5) ne comprend pas le mot clé \_rollover

Rollover API est introduit en 5.0.0 seulement.

Savez-vous quand elle sort la version stable 5.0.0?

Avant la fin de l'année très probablement.

David, je viens d'installer et testé la elasticsearch-5.0.0-alpha5 et positionné dans elasticsearch.yml:
node.box\_type: cold
