Hello, I just installed cratedb via docker and the header at the top says: License: crate (exp: 2019-03-31) I assume it’s the trial license documented here: [https://crate.io/products/cratedb-community-edition/](https://crate.io/products/cratedb-community-edition/) that I’m running now. Once expired will it automatically switch to community license? Is there a way to disable the trial license now and force it to switch to community one? (google doesn’t help) Thank you in advance, Roman ---

See [https://crate.io/docs/crate/reference/en/3.2/enterprise/index.html](https://crate.io/docs/crate/reference/en/3.2/enterprise/index.html). In short: You can switch to community edition by adding `license.enterprise: false` to your crate.yml configuration file of each node. ---

Unfortunately CrateDB 4.0.6 don’t know this config option anymore: ``` [2019-10-24T16:31:02,298][WARN][o.e.b.ElasticsearchUncaughtExceptionHandler] [Faulkogel] uncaught exception in thread [main] org.elasticsearch.bootstrap.StartupException: java.lang.IllegalArgumentException: unknown setting [license.enterprise] please check that any required plugins are installed, or check the breaking changes documentation for removed settings ``` Is there a new method of getting back to the community version? ---

Since CrateDB 4.0, we differentiate between CrateDB CE (Community Edition) and CrateDB (Enterprise) at build time. A CrateDB version cannot be switched to CrateDB CE by configuration anymore. Although the CrateDB variant can be run without a paid license on up to 3 nodes. This license switch was introduced in 3.3, see also [https://crate.io/a/cratedb-3-3-is-now-stable-and-ready-for-use/](https://crate.io/a/cratedb-3-3-is-now-stable-and-ready-for-use/). We also don’t distribute any CrateDB CE variant but it can be easily build from source by `./gradlew communityEditionDistTar`, see [https://github.com/crate/crate/blob/master/devs/docs/basics.rst#manual-build](https://github.com/crate/crate/blob/master/devs/docs/basics.rst#manual-build). ---

@smu I hope you’re planning on offering a community edition rpm similar to how docker works (docker vs docker-ce)…If you’re requiring people to build crate community edition, it seems like a step backwards for those of us who’ve been with you since 0.5 days 😃 and makes me wonder if crate will eventually pull a memsql where you no longer will offer a community edition or if you do, you’d limit it to a max number of nodes. ---

we don’t have plans to distribute a community edition, but you can either build it yourself - or apply for a special startup pricing (based on funding level and size of the cluster) or free licensing for non-commercial or educational projects. feel free to get in contact with me directly! ---

@jodok, @smu with all those version changes I don’t understand the final terms. Can CrateDB be used unlicensed up to three nodes? Because I am trying to upgrade a mono node deployment from version 3.0.7 to 4.0.10 and a trial license has been created to the instance. So, will my deployment stop when the trial license expires? would I be able to keep using version 4.0.10 if the deployment has 3 or fewer nodes? do I have to explicit this using any kind of env or configuration file? Thank you in advance ---

I am having a similar question as you’ve asked. +1 ---

Hi, starting with Crate 4.x the license for up to 3 nodes will not expire to allow using CrateDB without a license. If you add a 4th node, the cluster will run in restricted mode. If the trial license was generated by a 4.x node itself during first start you should be good to go. You do not have to reconfigure anything.
