L3 - Default Context:
The issue was raised that once a process instance has more than 10 000 activit instances/flow nodes Optimize will raise an exception since Elasticsearch won't allow Optimize to add more than 10 000 nested documents. In order to be able to fix the issue, the user should be able to adjust the limit.
Error that occurs:
[5]: index [optimize-process-instance_v4], type [_doc], id [], message [ElasticsearchException[Elasticsearch exception [type=mapper_parsing_exception, reason=The number of nested documents has exceeded the allowed limit of [10000]. This limit can be set by changing the [index.mapping.nested_objects.limit] index level setting.]]]
AT:
- the index.mapping.nested_objects.limit for all Optimize indexes in Elasticsearch can be configured in the Optimize configuration file
- the new configuration is added to the documentation
- the documenation of the config contains a hint that increasing this value might cause memory issue in Elasticsearch and/or slow down the search significantly
Hint:
Some possible options are:
- the index.mapping.nested_objects.limit for all Optimize indexes in Elasticsearch can be configured in the Optimize configuration file
- the documenation of the config contains a hint that increasing this value might cause memory issue in Elasticsearch and/or slow down the search significantly
