How to set the data directory of ElasticSearch with Spring Boot

Question

My problem is similar to [1] I have a spring boot appplication where I save some document in elasticsearch. The index is created in a data dir in the current directory each time. I want to change this default path to a given one. How can I do that? A such a simple task takes hours to find it out.

I tried many things:

1. @Setting(setting="/data/elasticsearch")
2. In an elasticseacrh.properties and application.properties file:
   1. path.data
   2. spring.data.elasticsearch.path.data

Without any luck.

Answer 1

1. Adding the path with the configuration file in my application class:

   @Setting(settingPath = "/home/topic/src/main/resources/elasticsearch.properties")
   

2. Set the path.data property in the file:

   path.data=/Users/mimis/Desktop/data
   

Did the trick.

Update:
With Spring Boot 1.3.0 we can add any Elasticsearch property in the application properties files by using the spring.data.elasticsearch.properties.* prefix. For example:

spring.data.elasticsearch.properties.data.path=/path/to/data
