Market Recognition

• Named as a Strong Performer in The Forrester Wave™: Big Data Streaming Analytics, Q1 2016.

• Highest score possible in 'Acquisition and Pricing' criteria, and among second-highest scores in 'Ability to execute' criteria

• The Forrester Report notes…..

“WSO2 is an open source middleware provider that includes a full spectrum of architected-as-one components such as application servers, message brokers, enterprise service

bus, and many others.

Its streaming analytics solution follows the complex event processor architectural approach, so it provides very low-latency analytics. Enterprises that already use WSO2 middleware can add CEP seamlessly. Enterprises looking for a full middleware stack that includes streaming analytics will

find a place for WSO2 on their shortlist as well.”

Experian delivers a digital marketing platform, where CEP plays a key role to analyze in real-time customers behavior and offer targeted promotions. CEP was chosen after careful analysis, primarily for its openness, its open source nature, the fact support is driven by engineers and the availability of a complete middleware, integrated with CEP, for additional use cases.

Eurecat is the Catalunya innovation center (in Spain) - Using CEP to analyze data from iBeacons deployed within department stores to offer instant rebates to user or send them help if it detected that they seem “stuck” in the shop area. They chose WSO2 due to real time processing, the variety of IoT connectors available as well as the extensible framework and the rich configuration language. They also use WSO2 ESB in conjunction with WSO2 CEP.

Pacific Controls is an innovative company delivering an IoT platform of platforms: Galaxy 2021. The platform allows to manage all kinds of devices within a building and take automated decisions such as moving an elevator or starting the air conditioning based on certain conditions. Within Galaxy2021, CEP is used for monitoring alarms and specific conditions.Pacific Controls also uses other products from the WSO2 platform, such as WSO2 ESB and Identity..

A leading airline uses CEP to enhance customer experience by calculating the average time to reach their boarding gate (going through security, walking, etc.). They also want to track the time it takes to clean a plane, in order to better streamline the boarding process and notify both the airline and customers about potential delays. They evaluated WSO2 CEP first as they were already using our platform and decided to use it as it addressed all their requirements.

Realtime Analytics

Realtime Analytics

It’s about :

• Gather data from multiple sources• Correlate data streams over time• Find interesting occurrences • And Notify • All in Realtime!

Realtime Processing Pipeline

Realtime Execution

• Process in streaming fashion (one event at a time)

• Execution logic written as Execution Plans • Execution Plan

– An isolated logical execution unit– Includes a set of queries, and relates to multiple input and output

event streams– Executed using dedicated WSO2 Siddhi engine

Realtime Processing Patterns

• Transformation

– projection, transformation, enrich, split

• Temporal Aggregation

– basic stats, group by Aggregation, moving averages

• Alert and Threshold

• Event Correlation

• Trends

– detecting rise, fall, turn, triple bottom

• Partitioning

• Join Streams

• Query Data Store

Siddhi Query Syntax

define stream <event stream>(<attribute> <type>,<attribute> <type>, ...);

from <event stream>select <attribute>,<attribute>, ...insert into <event stream> ;

define stream SoftDrinkSales (region string, brand string, quantity int, price double);

from SoftDrinkSalesselect brand, quantityinsert into OutputStream ;

Output Streams are inferred

Siddhi Query ...

from SoftDrinkSalesselect brand, avg(price*quantity) as avgCost,‘USD’ as currencyinsert into AvgCostStream

from AvgCostStreamselect brand, toEuro(avgCost) as avgCost,‘EURO’ as currencyinsert into OutputStream ;

Enriching Streams

Using Functions

Siddhi Query ...

from SoftDrinkSales[region == ‘USA’ and quantity > 99]select brand, price, quantityinsert into WholeSales ;

from SoftDrinkSales#window.time(1 hour)select region, brand, avg(quantity) as avgQuantity

group by region, brandinsert into LastHourSales ;

Filtering

Aggregation over 1 hour

Other supported window types: timeBatch(), length(), lengthBatch(), etc.

Siddhi Query (Filter & Window)

define stream Purchase (price double, cardNo long,place string);

from every (a1 = Purchase[price < 10] ) -> a2 = Purchase[ price >10000 and a1.cardNo == a2.cardNo ]

within 1 dayselect a1.cardNo as cardNo, a2.price as price, a2.place as placeinsert into PotentialFraud ;

Siddhi Query (Pattern) ...

define stream StockStream (symbol string, price double, volume int);

partition by (symbol of StockStream)begin from t1=StockStream, t2=StockStream [(t2[last] is null and t1.price < price) or

(t2[last].price < price)]+within 5 min

select t1.price as initialPrice, t2[last].price as finalPrice,t1.symbol insert into IncreaingMyStockPriceStream end;

Siddhi Query (Trends & Partition)

define table CardUserTable (name string, cardNum long) ;

@from(eventtable = 'rdbms' , datasource.name = ‘CardDataSource’ , table.name = ‘UserTable’, caching.algorithm’=‘LRU’)define table CardUserTable (name string, cardNum long)

Cache types supported

• Basic: A size-based algorithm based on FIFO.• LRU (Least Recently Used): The least recently used

event is dropped when cache is full.• LFU (Least Frequently Used): The least frequently used event is dropped

when cache is full.

Siddhi Query (Table) ...

Supported for RDBMS, In-Memory, Analytics Table,

In-Memory Data Grid (Hazelcast )

from Purchase#window.length(1) join CardUserTableon Purchase.cardNo == CardUserTable.cardNum

select Purchase.cardNo as cardNo, CardUserTable.name as name,Purchase.price as price

insert into PurchaseUserStream ;

from CardUserStreamselect name, cardNo as cardNumupdate CardUserTable

on CardUserTable.name == name ;

Similarly insert into and delete are also supported!

Data Abstraction Layer

Custom

Data Persistence ...

• Analytics Tables– The data persistence entity in WSO2 Data Analytics Server– Provides a backend data source agnostic way of storing and

retrieving data– Allows applications to be written in a way, that it does not

depend on a specific data source, e.g. JDBC (RDBMS), Cassandra APIs etc..

– WSO2 DAS gives a standard REST API in accessing the Analytics Tables

Data Persistence ...

• Analytics Record Stores– An Analytics Record Store, stores a specific set of Analytics

Tables– Event persistence can configure which Analytics Record

Store to be used for storing incoming events– Single Analytics Table namespace, the target record store

only given at the time of table creation– Useful in creating Analytics Tables where data will be stored

in multiple target databases

Incremental Processing

• Requirement– Data aggregations to be done efficiently as time series data is updated

continuously– Aggregation lookup operations to be done with any given time range

Spark

Incremental Processing ...

• Solution– Streaming data is first processed using the CEP engine for immediate

aggregation operations such as “avg”, “min”, “max”, “sum” etc… for smaller time intervals, such as 1s and 1m. And the resultant data records are persisted

– The persisted aggregation data for smaller time ranges (i.e. 1s, 1m) are looked up and further larger level aggregations are done. This step is done using batch analytics (Spark SQL). A custom extension is done here to allow incremental processing to Spark, where earlier processed data is not recomputed, rather the last checkpoint is remembered by the system

– O(log n) computation complexity
