I would like to store reflection data in S3, but cannot find any documentation of how to configure the connection. In `dremio.conf` I imagine I will need to put the path to the s3 bucket in the `paths.dist` field, but how do I specify the S3 access credentials?

You need to put your s3 credentials into core-site.xml

```
<property>
  <name>fs.s3a.access.key</name>
  <value>ACCESS-KEY</value>
</property>

<property>
  <name>fs.s3a.secret.key</name>
  <value>SECRET-KEY</value>
</property>

```

and have it sourced on dremio classpath (for example copy it to dremio conf directory)

Perfect, thanks for the reply. Is this documented somewhere?

Not at this time, but we will be adding it shortly. Thanks for pointing this out!
