Failed to create Incremental Reflection on ElasticSearch

Hi, guys! I’m trying to create an Incremental Reflection from an index using the timestamp field but I’m getting this error:

Dremio only supports incremental column update on BIGINT types. The identified column was of type TIMESTAMP.

My mapping on ES of this field in particular is:

@timestamp": {
   "type": "date"

and the data is in this format: 2017-09-01 07:24:49.767.

Do you have some workaround? This index is append-only and grows really fast.

Dremio does recognize this field as Date and suggests to me using it:

Captura de Tela 2017-09-13 às 21.39.39

Any idea guys? :pensive:

Hi Allan,

Would you please be able to send us the profile from the failed job?


It doesn’t even have a plan :thinking:, look:


Hi Allan,

Can you please click on jobs, download the profile for this failed job and send us the zip file downloaded? I will get back to you once I have a look.

@allan.sene, did you manage to solve this? I’ve hit the same problem with MongoDB dataset. Reported it here: Dremio only supports incremental column update on BIGINT types - why?. But thought you may know a solution given that someone from Dremio was trying to help you.

No, I didn’t :pensive:

At the time, we decided to take a break of Dremio’s project and try other alternatives.

Hey guys,

Thanks for raising this requirement. We are tracking this internally, and will provide updates as they arise.


Hi all,

the issue seems to be backend independant. I have the same issue with a Postgres DB as backend where the incremental column (in my case a column named “modifed_at”) is defined as a TIMESTAMP.

Are there any news on the issue?

I will test a workaround by converting the timestamp to a BIGINT and see if the incremental update will work then.


Hello, did converting the timestamp to BIGINT work for you?
