andygrove opened a new issue, #2198:
URL: https://github.com/apache/datafusion-comet/issues/2198
### Describe the bug
When I implemented `auto` scan mode, I overlooked the checks for encryption
being enabled.
We choose a specific scan in the following code, which does not check for
encryption, so will likely pick `native_iceberg_compat` in most cases:
```scala
// if scan is auto then pick the best available scan
if (scanImpl == SCAN_AUTO) {
scanImpl = selectScan(scanExec, r.partitionSchema)
}
```
Later on we fall back to Spark if encryption is enabled and then scan is not
`native_comet`.
```scala
val encryptionEnabled: Boolean =
conf.getConfString("parquet.crypto.factory.class", "").nonEmpty &&
conf.getConfString("parquet.encryption.kms.client.class",
"").nonEmpty
if (scanImpl != CometConf.SCAN_NATIVE_COMET && encryptionEnabled) {
fallbackReasons +=
"Full native scan disabled because encryption is not supported"
return withInfos(scanExec, fallbackReasons.toSet)
}
```
