Can we run elastic search "individually" on each Bitbucket cluster?

SATOSHI ISOMATSU_g4wgme

Hi 

I've been using Bitbucket Data Center version and I installed elastic search on the local instance. Then, 2nd cluster connects to the elastic search which is installed at 1st cluster. However, this is a risk to lost the functionality of elastic search when the 1st cluster (instance) is down.

My question is:

Is it OK to install and run elastic search on each cluster individually (no replication) ?

The reason why I do not want to use replication setting is to simplify those scale out.

As my guessing, it will consume CPU and memory more for indexing but the result would be same.

Please let me know if there is any issues.

Thanks.

Hi Satoshi,

 

You should only use one single Elasticsearch for Bitbucket Server, all Bitbucket Server nodes will then connect to it via the settings specified in the shared bitbucket.properties file. The instructions are available on the Install and configure a remote Elasticsearch instance page.

 

Elasticsearch also provides the ability to run in a clustered installation. Bitbucket Server can connect to a clustered Elasticsearch. From our documentation:

Bitbucket Data Center can have only one remote connection to Elasticsearch for your cluster. This may be a standalone Elasticsearch installation or a clustered installation behind a load balancer. 

 

@Craig Castle-Mead's suggestion to use an additional server for Elasticsearch is also a valid one to avoid issues if a node of the cluster is unavailable.
