I have the following index templates that have been working up until Elasticsearch 2.3.4. After I upgraded my Elasticsearch to 2.4, it seem to have broken. I am out of idea where I could be doing wrong. Some help is really appreciated. **step-1** : I have inserted and verified that the following index template exists: `curl "http://localhost:9200/_template"` `{"stats":{"order":0,"template":"stats-*",...,"mappings":{"_default_":{"dynamic_templates":[...{"timestamp_fields":{"match_pattern":"regex","mapping":{"type":"date","doc_values":true},"match":".*[tT]imestamp"}}],"date_detection":false,...}` (full index in Appendix) **step-2** : I understand that index templates are only applied during index creation. So I deleted all existing indices first. `curl -XDELETE "http://localhost:9200/stats-*"` **Step-3** : Then, I insert the data using Bulk API. `curl -XPOST "http://localhost:9200/_bulk" --data-binary @data.json` data.json `{"index":{"_index":"stats-2016.10","_type":"MyType","_id":"xxxxyyyy"}}` `{"@version":"1","@timestamp":"2016-10-30T06:00:00Z",....}` **Step-4** : Then, I checked the field data type (of @timestamp) as follows: `curl -XGET "http://localhost:9200/stats-2016.10/_mapping/MyType/field/@timestamp"` My understanding is that the bulk inserts should cause the indexes to be automatically created and since the index name (stats-2016.10) matches the index template (stats-\*), the template should have applied. Then, I expect that fields that end with "[tT]imestamp" should have "date" type mapping. Therefore, Expected (was seen in ES 2.3.4): > { > "stats-2016.10": { > "mappings": { > "MyType": { > "@timestamp": { > "full\_name": "@timestamp", > "mapping": { > "@timestamp": { > "type": "date", > "format": "strict\_date\_optional\_time||epoch\_millis" > } > } > } > } > } > } > } But, Actual (seen in ES 2.4): > { > "stats-2016.10": { > "mappings": { > "MyType": { > "@timestamp": { > "full\_name": "@timestamp", > "mapping": { > "@timestamp": { > "type": "string", > "fields": { > "raw": { > "type": "string", > "index": "not\_analyzed" > } > } > } > } > } > } > } > } > } All the above have been working fine until until ES 2.3.4. I upgrade my ES to version 2.4 and it stops working. Did I miss some configurations that should do but didn't? what else could be wrong? Thanks in advance.

Hi @kaung You should move `timestamp_fields` to the first in dynamic\_templates, I think. See: [https://www.elastic.co/guide/en/elasticsearch/reference/current/dynamic-templates.html#dynamic-templates](https://www.elastic.co/guide/en/elasticsearch/reference/current/dynamic-templates.html#dynamic-templates) ---

@johtani. Thanks and Indeed, swapping the order fixes it. Also since the doc page you mentioned says "Templates are processed in order — the first matching template wins." So that makes sense. I am curious why it has been working from ES 1.7 thru 2.3.x though. I re-did the test to be sure. Up until ES 2.3.5, the mapping for "[tT]imestamp fields was "date" regardless of the ordering in the index template. It seems to me there used to be something else apart from which template appear first. ---

Did you use exactly same template? Did you set `date_detection:false`? I didn't read the code honestly, I just would like to ask it. ---

Yep. It's exactly the same template. `date_detection:false`. Tested with the same 4 steps listed in my post . ---
