Known issues

Error during migration of Dashboards when Updating from Optimize 3.2.0 to 3.3.0

During the update from Optimize 3.2.0 to 3.3.0 you may encounter the following error:

Starting step 6/7: UpdateIndexStep on index: dashboard
Progress of task (id:FwvhN1jsRUe1JQD49-C3Qg:12009) on index optimize-dashboard_v4: 0% (total: 1, updated: 0, created: 0, deleted: 0)
An Elasticsearch task that is part of the upgrade failed: Error{type='script_exception', reason='runtime error', phase='null'}

This can happen if you started using an Optimize version prior to 3.1.0 in your environment in the past and did not manually edit/update at least one particular dashboard created with such a version since then.

To recover from this situation you can run the following update script on all Optimize dashboards on your elasticsearch cluster:

curl --location --request POST 'localhost:9200/optimize-dashboard_v3/_update_by_query' \
--header 'Content-Type: application/json' \
--data-raw '{
    "script": {
        "source": "if (ctx._source.availableFilters == null) { ctx._source.availableFilters = [] }",
        "lang": "painless"
    }
}'

and then resume the update to Optimize 3.3.0 by just rerunning it, thanks to Optimize updates being resumable since Optimize 3.3.0.

Breaking Changes

Renamed environment folder to config

The environment folder, which holds all configuration files has been renamed to config.

Elasticsearch

Optimize no longer supports Elasticsearch versions 7.0, 7.1 or 7.2. See the Supported Environments sections for the full range of supported versions.

Docker Image Environment Variables

Previously it was possible to use the JAVA_OPTS environment variable on the official Optimize Docker Image to configure the JVM that runs Optimize. With Optimize 3.3.0 this variable got renamed to OPTIMIZE_JAVA_OPTS.
