TransCo
A customer requests a quote
A server goes down
A website visitor clicks on a link
A financial transaction is booked
A delivery truck pings its GPS coördinates
TransCo
All these have a similar thing:
They Generate Events

Events
Events
Events used to manipulate their master data
Events
Today, events ARE their master data
TransCo
Isn't this a big data presentation?
Hang on, We'll get to that
Events
An event isTime basedRecord linkedField orientedIncrementalImmutable
Events
A new customer is addedADD [ts=1,id=123,field="name",value="Daan Gerits"]
ADD [ts=1,id=123,field="address",value="MyStreet 40"]
A customer is updatedADD [ts=13,id=123,field="address",value="AnotherStreet 1"]
Eventually a customer is removedADD [ts=43,id=123,field="address",value=]
Events
Notice I only created new records
No UpdatesNo Deletes
CRUD becomes CR
Events
Oh no, I shouldn't have done that!DELETE [ts=43,id=123,field="address"]

Big Data
So what has all this to do with Big Data?
Only appending eventsneed to store a lot of data
=> HDFS, HBase, ...
need batch processing=> MapReduce, Pig, Hive, ...
need real-time processing=> Storm, S4, ...
Big Data
Allows trendingdriver statistics for his whole career
Allows state regenerationthe state of all master data on februari 12, 2005
Is human-error-proofremove the last event on this record
Scales very well
Event Driven Organisation
By storing events
By generating focussed views

How to solve this?Store events in 2 locations

Buffer DB has - data of last x hours- data, not events
