The document outlines a presentation by Mariano Gonzalez at the Chicago Cloud Conference 2020, focusing on architecting analytic pipelines on Google Cloud Platform (GCP). It covers various GCP services such as BigQuery, Dataflow, and Pub/Sub, highlighting their features, benefits, and comparisons with other technologies like Kafka and Apache Spark. The presentation aims to find an elegant, scalable, and cost-effective way to build and deploy data/analytic pipelines using these services.
Architecting Analytic Pipelines on GCP - Chicago Cloud Conference 2020
- 1. Chicago Cloud Conference 2020 Architecting Analytic Pipelines on GCP
- 2. Who am I? Mariano is an engineer with more than 15 years of experience with the JVM. He enjoys working with and exploring a variety of big data technologies. He is an avid open-source contributor. Data/Platform Architect at Otus Mariano Gonzalez Most importantly, I am just a person trying to learn about and share big data technologies and approaches.
- 3. Agenda ● Goal for this session ● Overview of GCP services ● Apache Beam and GCP Dataflow ● Natural Language Processing for sentiment analysis ● Demo ETL/Analytics ● QA
- 4. Goal for this Session Find an elegant way to build and deploy data/analytic pipelines that: ● Support for multiple workloads ● Scale compute and storage independently ● Backed up by manage services ● Cost effective
- 5. Common Architecture Analytics Pipeline Data Storage Different Types and Formats of Data Analytic/Data Pipelines User
- 6. Overview of GCP services - App Engine ● Good alternative if K8s infrastructure is not in place ● Easy deployment ○ Similar to AWS SAM from a CLI perspective ○ Similar to AWS Beanstalk from a deployment perspective ● Well integrated with other cloud services ○ GCP docker Registry ● Multiple Runtimes ○ Custom (Docker) ○ JVM/Node/Python
- 7. Overview of GCP services - Storage ● Hot - durable, available performance object storage for frequently accessed data ○ Amazon S3 Standard ○ Microsoft Azure Hot Blob Storage ○ Google Cloud Storage standard ● Cool - storage class for data that is accessed less frequently, but requires rapid access when needed ○ Amazon S3 Standard I/A and S3 Standard Z-I/A ○ Microsoft Azure Cool Blob Storage ○ Google Cloud Storage Nearline ● Cold - secure, durable, and low-cost storage service for data archiving ○ Amazon S3 Glacier ○ Microsoft Azure Blob Archive Storage ○ Google Cloud Storage Coldline
- 8. Overview of GCP services - Pubsub Why not just use Kafka? ● Fully managed services ○ Both system can have fully managed version in the cloud ● Cloud vs On-prem ○ Pubsub is only offered as part of the GCP ecosystem whereas Apache Kafka can be used as a both cloud service and on-prem service ● Message duplication ○ Kafka manage the offsets via zookeeper ○ Pubsub works using acknowledging the message
- 9. Overview of GCP services - Pubsub Why not just use Kafka? ● Retention policy ○ Both Kafka and Pubsub have options to configure the maximum retention time ● Consumers Group vs Subscriptions ○ Pubsub use subscriptions, you create a subscription and then you start reading messages from that subscription ○ Kafka use the concept of "consumer group" and "partition"
- 10. Overview of GCP services - BigQuery ● Query engines probably one of the most competed service today: ○ Snowflake ○ Presto ○ Redshift ● How are these warehouses different?
- 11. ● Presto ○ Self hosted open source solution ● Pre-RA3 Redshift ○ Somewhat more fully managed, but still requires the user to configure individual compute clusters with a fixed amount of memory, compute and storage ● Redshift RA3 ○ Closer to the user experience of Snowflake by separating compute from storage ● Snowflake ○ The user only configures the size and number of compute clusters ○ Every compute cluster sees the same data ○ Compute clusters can be created and removed in seconds Overview of GCP services - BigQuery
- 12. BigQuery ● Flat-rate is similar to Snowflake except there is no concept of a compute cluster, just a configurable number of "compute slots" ● Pure serverless model, where the user submits queries one at a time and pays per query ● On-demand mode can be much more expensive, or much cheaper, depending on the nature of your workload A "steady" workload that utilizes your compute capacity 24/7 will be much cheaper in flat-rate mode. A "spiky" workload that contains periodic large queries spaced with long periods of idleness or lower utilization will be much cheaper in on-demand mode. Overview of GCP services - BigQuery
- 13. What is Google Cloud Dataflow? ● Data processing service for both: ○ batch ○ real-time data streaming applications ● Benefits ○ Enables developers to set up analytic pipelines immediately ● Nextgen MapReduce ○ Designed to bring to an entire analytics pipelines the style of fast parallel execution that MapReduce brought to a single type of computational for batch processing jobs ○ It's based partly on MillWheel and Flume (two Google-developed data ingestion and low-latency processing). Overview of GCP services - Dataflow
- 14. Apache Beam SDK and Dataflow Runner Google Cloud Dataflow overlaps with services such as: ● Amazon Kinesis ● Apache Storm ● Apache Spark ● Facebook Flux $ java -jar build/libs/transformation-1.0-all.jar --project=ccc-2020-289323 --runner=DataflowRunner --streaming=true --region=us-east1 --tempLocation=gs://chicago-cloud-conference-2020/temp/ --stagingLocation=gs://chicago-cloud-conference-2020/jars/ --filesToStage=build/libs/transformation-1.0-all.jar --maxNumWorkers=2 --numWorkers=1
- 15. Apache Beam SDK and Dataflow Runner
- 16. Overview of GCP services - Dataproc On demand Hadoop Cluster ● From all the 3 managed services for Hadoop Clusters (Amazon EMR, Azure Hdinsight) Dataproc is the fastest to provision ● Easy runtime customization via PIP commands ● Not as well integrated with third party services (Azure Hdinsight - Databricks, Amazon EMR - Apache Zeppelin) $ gcloud beta dataproc clusters create cluster-name --optional-components=ANACONDA,JUPYTER --image-version=1.4 --enable-component-gateway --bucket=chicago-cloud-conference-2020 --region=us-east1 --project=ccc-2020-289323 --metadata 'PIP_PACKAGES=google-cloud-bigquery google-cloud-storage numpy pandas matplotlib'
- 17. Overview of GCP services - Cloud Natural Language API ● What can we do Cloud Natural Language API? ○ Reveal the structure and meaning of text via machine learning models ○ Extract information about people, places, and events, mentioned in text documents, news articles or blog posts ○ Understand sentiment about product on social media or parse intent from customer conversations happening in a call center or a messaging app ● How can we use it? ○ Analyze text uploaded as part of a HTTP request ○ Integrate with Google Cloud Storage
- 18. NLP - Sentiment Analysis Two type of metrics to consider: 1. Score a. It ranges between -1.0 (negative) and 1.0 (positive) and corresponds to the general emotional tendency of the text 1. Magnitude a. Indicates the general intensity of emotion (both positive and negative) in a given text, between 0.0 and inf b. Magnitude is not normalized and each expression of emotion in the text (both positive and negative) contributes to the value Sentiment Sample Values Positive score: 0.8, magnitude: 3.0 Negative score: -0.6, magnitude: 4.0 Neutral score: 0.1, magnitude: 0.0 Mixed score: 0.0, magnitude: 4.0
