Logstash: is it possible to save documents in memory?

Hello Folks,

I am trying to save data in memory that I would be able to retrieve quickly in my filter part. Indeed, when i receive new documents i want to retrieve former documents related in order to compute some new metrics.

Can anyone tell me if it is possible and if yes how could I achieve that ?

Thank you very much.


Depending on the specifics there's no stock filter for doing this. The ones that come closest are probably the collate, elasticsearch, and translate filters.

Ok thank you for the information. I am looking at these options.
I recently saw that there is an unofficial plugin 'memcached'. However, I don't know its performances.
