TPC-H with Trusted SparkSQL on Kubernetes#

Prerequisites#

Hardware that supports SGX
A fully configured Kubernetes cluster
Intel SGX Device Plugin to use SGX in K8S cluster (install following instructions here)

Prepare TPC-H kit and data#

Generate data

Go to TPC Download site, choose TPC-H source code, then download the TPC-H toolkits. Follow the download instructions carefully. After you download the tpc-h tools zip and uncompressed the zip file. Go to dbgen directory, and create makefile based on makefile.suite, and modify makefile according to the prompts inside, and run make.

This should generate an executable called dbgen
```
./dbgen -h
```
gives you the various options for generating the tables. The simplest case is running:
```
./dbgen
```
which generates tables with extension .tbl with scale 1 (default) for a total of rougly 1GB size across all tables. For different size tables you can use the -s option:
```
./dbgen -s 10
```
will generate roughly 10GB of input data.

You need to move all .tbl files to a new directory as raw data.

You can then either upload your data to remote file system or read them locally.

Encrypt Data

Encrypt data with specified Key Management Service (SimpleKeyManagementService, or EHSMKeyManagementService , or AzureKeyManagementService). Details can be found here: https://github.com/intel-analytics/BigDL/tree/main/ppml/services/kms-utils/docker

The example code of encrypt data with SimpleKeyManagementService is like below:

java -cp "$BIGDL_HOME/jars/bigdl-ppml-spark_3.1.2-2.1.0-SNAPSHOT.jar:$SPARK_HOME/conf/:$SPARK_HOME/jars/*:$BIGDL_HOME/jars/*"  \
  -Xmx10g \
  com.intel.analytics.bigdl.ppml.examples.tpch.EncryptFiles \
  --inputPath xxx/dbgen-input \
  --outputPath xxx/dbgen-encrypted
  --kmsType SimpleKeyManagementService
  --simpleAPPID xxxxxxxxxxxx \
  --simpleAPPKEY xxxxxxxxxxxx \
  --primaryKeyPath /path/to/simple_encrypted_primary_key \
  --dataKeyPath /path/to/simple_encrypted_data_key

Deploy PPML TPC-H on Kubernetes#

Pull docker image

sudo docker pull intelanalytics/bigdl-ppml-trusted-big-data-ml-python-graphene:2.1.0-SNAPSHOT

Prepare SGX keys (following instructions here), make sure keys and tpch-spark can be accessed on each K8S node

Start a bigdl-ppml enabled Spark K8S client container with configured local IP, key, tpch and kuberconfig path

export ENCLAVE_KEY=/path/to/enclave-key.pem

        $DOCKER_IMAGE bash

Attach to the client container

sudo docker exec -it spark-local-k8s-client bash

Modify spark-executor-template.yaml, add path of enclave-key, tpch-spark and kuberconfig on host

apiVersion: v1
kind: Pod
spec:
  containers:
  - name: spark-executor
    securityContext:
      privileged: true
    volumeMounts:
      ...
      - name: tpch
        mountPath: /ppml/trusted-big-data-ml/work/tpch-spark
      - name: kubeconf
        mountPath: /root/.kube/config
  volumes:
    - name: enclave-key
      hostPath:
        path:  /root/keys/enclave-key.pem
      ...
    - name: tpch
      hostPath:
        path: /path/to/tpch-spark
    - name: kubeconf
      hostPath:
        path: /path/to/kuberconfig

The optional parameter [QUERY] is the number of the query to run e.g 1, 2, …, 22.

The result is in OUTPUT_DIR. There should be a file called TIMES.TXT with content formatted like:
