| Description |
|
zabbix use a custom hashset function to implement valuecache , this method on a small memory of the original machine is better, now uses redis or memcached as valuecache implementation than the more common some of it? Only need to re-design and implement valuecache.c, so we can easily support redis or memcached. |

Could you please elaborate a bit on the possible benefits of using Redis as opposed to Zabbix's own implementation? |

We can very quickly get the latest values for item. Now if we want to get the latest value, we need to call the API interface or through zabbix‘s database to cross-table query. |

And, This place is recommended to design a hook. |

So the feature request is not so much about Redis, but more about a convenient and efficient way of getting latest values from Zabbix? If so, Note that Zabbix does not store all historical data in the value cache. It only stores the values it needs for trigger calculation (and maybe a few other things like calculated items), so if an item does not have a trigger, the value cache will not contain data for this item. In general, the contents of the value cache should not be relied upon. |

I do not think it will ever be implemented. |
