15. Why MongoDB
Flexible Schema
• No need to define Schema at collection creation
• Customized Schema per Stream
• Schema can be enriched in the middle of the Stream
{
"_id" : 1,
"timestamp" : 1521234568,
…
"data" : {
"hole_depth" : 10516.0,
"bit_depth" : 10513.8,
”rop" : 230.3,
"ml_predicted_rop”: 231.1,
”ml_optimized_rop" : 270.4
...
},
}

16. Why MongoDB
Enable Fast Data Growth
• Data growth is at 100GB/day
• Data in/out of our API is around 4TB / day
• One collection with 4.5TB of data
• Ability to add Shard and increase storage at exponential growth
• Response time with properly tuned index is near constant at growth
• Price per Storage compare to other solutions

17. Scale MongoDB
Index
• Design index for any type of query
• Primary ID + timestamp
• Partial Index
• Cluster query behavior based on existing index
• Create new index for new feature, consider what can be dropped
• Save on Index size, save the world
• Build index on 5TB collection takes a while
Shard
• Shard key needs to be indexed. Duh, or is it? What if it doesn’t fit?
• Try to utilize the most often used index.
• Using Hashed key for Shard.

18. Data-Driven Platform Features
Flexible Data Stream
• Data stream architecture that allow custom pipeline configuration
• Able to add custom apps to different streams depending on
customer
• Able to change configurations for each app
• Able to pilot custom apps with very limited system impact
Flexible Schema
• Flexible data driven API that allow one endpoint to handle
requests to different collections with different data schema
• /data/{provider}/{collection}/

19. Pot holes along the way
Tuning MongoDB
• Index / Sharing / Aggregation collections
• When to shard, how to shard
Lambda (Smoke and Mirrors of Serverless)
• 500+ million invokes per month
• Cold / Warm invoke & invoke exception behavior
• Logging; the 7 levels of CloudWatch hell
Scale and tune Kafka
• Topics / Partitions / Consumers configuration
Scale API
• Capability comes with responsibility and how to limit functions on
API (limits, index only queries)

20. Vision for Connected Wells Platform
Empowering users to optimize and improve operations while they happen
Reservoir Drilling
Completion
Production

21. Future Plans for MongoDB
IoT Time-series schema design
• Store data in aggregated format in raw collections
• Save on data storage
• Save on index size <- huge impact
Atlas Stitch
• Serverless functions enable REST API directly to Internet
• We utilize Google SSO & Key Auth
• VM? Docker? That’s so 2018…
• Automation of manual data input & workflows
• Automation for parsing PDF/Excel daily reports
