>                 Key: ATLAS-4555
>                 URL: https://issues.apache.org/jira/browse/ATLAS-4555
>             Project: Atlas
>          Issue Type: Bug
>          Components:  atlas-core
>    Affects Versions: 2.1.0, 2.2.0
>            Reporter: Albert Bikeev
>            Priority: Major
>         Attachments: atlas-application.properties

> h3. Environment:
>  * Cassandra 3.x, 30GB RAM, 4 CPU VM, maximum read latency 30ms
>  * Solr 7.7, 8 GB of RAM, 4 CPU VM
>  * Tested on both 2.1.x and 2.2.x
> h3. Problems:
>  * Startup time is 1-2 hours - applying default type-models patches
>  * Deletes and purges rate is around 25 entities per minute, so if there is a thousand records to remove it'll take 40 minutes
>  * When you want to edit an entity with big amount of references (like MySQL instance with a lot of databases) you could wait up to 5 minutes or even more before you see the full edit form
