IMHO this naming can be simplified. Other APIs here do not have the upload prefix.
Usage will be from BigQuery with bq.load.uploadTypeRows.

I think this should be named

Since this is temp, shouldn't we clean if afterward ?

I was thinking about bucket retention policy, but yeah, deleting it would be more optimal

on the other hand if I do:

  avro(
        List(blobId.toGsUtilUri),
        tableSpec,
        schema = Some(bqt.schema),
        createDisposition = createDisposition,
        writeDisposition = writeDisposition
  )

  storage.delete(blobId)

I am not confident that avro is fully synchronous and BQ doesn't read that file on the background

execute contains jobService.waitForJobs(loadJob) so I think this is fine.

I'm wondering also if we should create a SaveOps to allow saving some file formats (avro/json)

writeDisposition: WriteDisposition = WriteDisposition.WRITE_APPEND,
createDisposition: CreateDisposition = CreateDisposition.CREATE_IF_NEEDED
): Try[TableReference] = {
val bqt = BigQueryType[T]

Try {
val out = new ByteArrayOutputStream()
val datumWriter = new GenericDatumWriter[GenericRecord]()
val dataFileWriter = new DataFileWriter[GenericRecord](datumWriter)
try {
dataFileWriter.create(bqt.avroSchema, out)
rows.foreach { row =>
dataFileWriter.append(bqt.toAvro(row))
}
} finally {
dataFileWriter.close()
}

val blobId =
BlobId.fromGsUtilUri(
s"${tempLocation.stripSuffix("/")}/upload_${RandomStringUtils.randomAlphanumeric(10)}.avro"
)
val blobInfo = BlobInfo.newBuilder(blobId).build
client.blobStorage.createFrom(
blobInfo,
new ByteArrayInputStream(out.toByteArray),
Storage.BlobWriteOption.doesNotExist(),
Storage.BlobWriteOption.crc32cMatch()

blobId
}.flatMap { blobId =>
avro(
List(blobId.toGsUtilUri),
tableSpec,
schema = Some(bqt.schema),
createDisposition = createDisposition,
writeDisposition = writeDisposition
)
}
}
