6. Talk track: Both genotyping and market segmentation solutions have a useful design component known as percolation. The key idea is that there is a fast push to store data and an offline processing step that modifies data. The modified data could go back to the same data store or….Speaker: you might note that we show real-time steps in red; and non-real time steps in black.

9. Talk track: In market segmentation, you want to identify useful segments of your customer base to target for a market campaign, for retention, for specific product offerings, etc. What makes “good” segments depends on what you want to do and how the environment changes. You may not know ahead of time what categories make useful segments. One way to find this is to capture customer histories and do a clustering step for discovery and definition of the market segments.This market segment db is then queried and updated in response to new real-time data insertion or new rounds of clustering. Specific feature extraction may also be a useful step from the customer history persistence layer.
10. Talk track: the feature extraction step could be triggered by real-time data insertion…
11. Talk track: a second percolator processes new customer histories relative to the market segments.
12. Talk track: the clustering step is not triggered by the real-time insertion; it is a scheduled step and thus not an example of percolation.What about the other use case we said was similar, the Genotyping?
13. Talk track: MapR advantages include the smooth use of HBase on a MapR cluster for the persistence layer at the insertion point, or even better, the use of MapR M7 tables instead. There are two specific advantages to M7 (besides the all-important reliability):a)Less risk of delays/ IO storms etc that can happen with HBase. This is VERY important when pushing real-time data to a data store.b) Strategic advantage of using in-memory flags on column families – very efficient in M7 where you can have lots of column families as opposed to only a few in HBase, operationally speaking.
14. Talk track: Now let’s consider the other health data example, genome sequencing for personalized medicine. This is an approach that can be used to get the particular genomic characteristics of a cancerous tumor and compare to known patient histories in order to select the best option for a customized therapy.
15. Talk track: While percolation is not used in this example, it does represent a specialized form of recommendation: user-based recommendation.In this genome sequencing/ personalized medicine example, A very high bar is set for the accuracy of the recommendation. Here a user-based pattern is best. Let’s look at the generalized form…
16. Talk track: here is the basic pattern for user-based recommendation, as used in the real use case of personalized medicine. In contrast, In consumer recommendation for shopping or movie or music recommendation, rapid response is key and accuracy is slightly less important. There item-based recommendation is generally best, because the expensive step in computing co-occurrence can be done offline prior to a user query.
