Hi all,

Just had a quick question regarding using a custom (paid for) Maxmind GeoIP database, rather than the bundled one in Logstash.

My question is if Logstash reads against the database each time the plugin is called in a Logstash filter, or if the database is opened/read into memory at the point Logstash starts up?  
I'm trying to determine if having the file simply update on disk is sufficient to see changes represented i Logstash, or if the Logstash daemon would need restarting after the database file has been updated?

Cheers,  
Mike

I see I didn't search hard enough -- Apparently the answer is that Logstash does require a restart in these cases: [GeoIP filter - database file updated - restart required?](https://discuss.elastic.co/t/geoip-filter-database-file-updated-restart-required/155200)
