MongoDB Query Language is Powerful

How do we see customers using Tableau on MongoDB

• Use Case–Data Exploration/Mining–Ad-Hoc Report Conceptual Modeling–Query directly/Explore Concepts to Migrate to Analytically Optimized

Data Stores

MongoDB

• Financial Services: Analyze ticks, tweets, satellite imagery, weather trends, and any other type of data to inform trading algorithms in real time.

• Government: Identify social program fraud within seconds based on program history, citizen profile, and geospatial data.

• HighTech: Identify unique individuals across any type of device, browser or app and use a holistic behavioral model to advertise to them.

• Retail: Set up a digital geo-fence around your brick-and-mortar locations to push in-store incentives to shoppers in real time.

• MongoDB – Verticals & Use Cases

Basic MongoDB Optimizations

✔ DO: ✗ AVOID

• Model for use

• Index effectively

• Use prejoined array tables

• Leverage custom pipelines in DRDL

• Let dates (SQL timestamp) and decimal

types flow w/o conversion to string

• Casts

• Date arithmetic

• Cross-collection

• Non-equijoins

• Subqueries

Tableau Data Extracts – When to use them?

Extracts Recommended Live Connection Recommended

• Slow SQL to MQL translation

• Smaller dataset sizes needed

• Offline analysis required

• Reduce “big query” impact on

nominal workload performance**

• Fast SQL to MQL translation

• Larger dataset sizes needed

• Real-time analysis required

• Extract Sampling Techniques• Filters

• Keep only well-known dimensions and measures• Use short date ranges

• Aggregates• Aggregate dimensions and measures when possible• Roll-up dates when possible

• Samples• Utilize Custom SQL with sample function

• Top N• May be skewed since non-random sampling

Optimize your Tableau Data Extracts

General Techniques for Improvement

Partition field as filter

Single denormalized table

Monitor for long running queries• Data blending large datasets

– Executed on the Tableau client side• Cull Unnecessary joins

– …and take advantage of prejoined tables in the BI Connector– Imperfectly implemented on many big data systems– Assume referential integrity

• Inefficient formulas

MongoDB

Leverage a multi-tiered approach based on your data

Raw data (large)

MongoDB

• Chunks of Human Consumable Data• Aggregation of Data Tiers

• Year to Quarter to Month to Week to Day to Records

• Region to Country to State to County to Zip Code

• Drill Down to Raw Data with Context• Use Aggregates for Guided Drilling• Use Action Filters to Navigate the

Pyramid

1. Do you have sufficient infrastructure/hardware to deal with the kind of data that will be analyzed? ~ Law of inertia , nothing moves till there is sufficient force applied to move it

2. Have you chosen an underlying data source that matches your performance aspirations, and have you engineered it for interactive performance? ~ law of dynamics, Force = mass * acceleration

3. Have you designed your Tableau vizzes so that the queries run efficiently? ~ For every action (viz) there is an equal and opposite reaction (from the data source)

Don’t forget the laws of Data Motion
