Informix MQTT Streaming

Informix Spark Streaming is an extension of Informix that allows data to be streamed out of the database as soon as it is inserted, updated, or deleted.
The protocol currently used to stream the changes is MQTT v3.1.1 (older versions not supported!). This extension is able to stream data to any MQTT broker where it can be processed or passed on to subscribing clients for processing.

  9. 9. Real-Time Operational Database Streaming Analytics with Spark  Applications that drive business have positioned relational databases at the center of operations.  To continue their success, businesses need to use streaming analytics to gain real-time insights into their operations and take actions to optimize outcomes.  Infrequent batch analytics on “stale” data losing competitive edge. Increasing demand for real-time analytics to stay in the lead. 9
  10. 10. SENSE -> ANALYZE -> ACT  As data ages, business value diminishes.  Sense → Analyze → Act in seconds/ milliseconds, not days or weeks Sens e Analyze ActSens e Analyz e ActDays Days Seconds Days Seconds Batch Real- time 10

  12. 12. Real-time analytics - Industry  Information technology – Systems & Network monitoring  IoT - sensor data analytics and processing  Financial transactions – authentication, fraud detection, validation  Inventory control – consumer trends and demands  Website analytics – ad targeting  Many others…. 12
  13. 13. Real-time analytics - applications  Data analyzed as it arrives – data in motion  Simple: Monitoring, alerts/reports, statistics  Complex: predictive analytics (regressions, machine learning, etc…), K-means clusters (classification, anomaly detection)  Many store events as well, combine with later batch processing.  Immediate actions possible. 13
  14. 14. Informix to Spark Challenges 14
  15. 15. Exploring data and discovering actionable business insights  The problem - Often users will not know what exact analytics they want to do  Difficult to justify cost/risk of a complex solution without specific business value  Need to reduce the cost/risk of adding real-time data analytics pipeline to application architecture  Let data scientist explore data to find useful data analytics without interfering with existing business. 15
  16. 16. We're running an Informix database. How to incorporate real-time analytics into our application architecture? Application Server Database 16
  17. 17. Out-dated approach - requires additional complexity Increased risk and cost. Application Server Additional Component Additional Component 17
  18. 18. Informix to Spark Prototype Implementation 18
  19. 19. Real-Time Operational Database Streaming Analytics with Spark  Newly prototyped feature for the Informix database.  Enables Informix customers to stream data added to their database in real-time via MQTT, which can then be consumed by an analytics platform such as Apache Spark. 19
  20. 20. Informix MQTT Streamer – Enable real- time analytics pipeline which drastically reduces complexity, cost and risk 20
  21. 21. How is it implemented?  Uses Informix Virtual-Index Interface (VII)  VII allows us to write UDRs that will be triggered whenever certain SQL statements are executed  This is typically used to create indexes for custom data types. Instead, we use it to write data to a socket during INSERT/UPDATE statements VII UDR: Publish to MQTT broker MQTT broker 21
  22. 22. Installation and basic usage  Open Sourced!  Available on github – https://github.com/IBM-IoT/InformixSparkStreaming  Run install script  Add the streaming index to the column whose values you want to stream create index stream on table(col1, col2) USING streaming_index; 22
  23. 23. The Nitty gritty • Installed into Informix is a set of custom UDRs that convert data into MQTT messages and sends them to a specified address • Virtual Table Indexes detect data insert/update/deletes as they happen and trigger the messages to be sent • Once in an MQTT broker, almost anything can consume it – MQTT clients available for most programming languages (include Java for Apache spark) • Spark can analyze the data, compare it to historical data, use streaming k-means algorithms to determine changes in the data
  24. 24. The Nitty gritty continued  Once installed, the custom “streaming_index” index type will be available for use.  Running the “create index” command and specifying to use the “streaming_index” index type will run the code in the custom UDRs that will push the data via MQTT.  Then, whenever you run the INSERT statement on the column that you created the streaming index on, the data that you inserted will automatically be published to an MQTT broker.  See the “IBM Informix Virtual-Index Interface Programmer's Guide” for more details. 24
  25. 25. In-depth  Does the prototype work for Temp. tables?  No specific index-related restrictions to temp. tables  Do we lock the tables?  The VII will lengthen the amount of time a lock is held  Future item - multiple concurrent writers to a per-table queue, flushed asynchronously by a separate thread  Would this work for multi-nodes (sharding)?  The current prototype is really delegating this to Spark, where multiple input streams could be merged into one 25
  26. 26. In-depth  Installs in seconds  No need to upgrade database  No need to restart database server  Can be installed and activated on a live production database!  Minimal interference with existing business application 26

  28. 28. Heart To Spark • Demonstration for real time streaming of data from the Informix engine into a message broker for digestion by one or more services • Simulates IOT data from a heart rate monitor • Watches for trends in heart rates – Poor health/stress can cause a rise in baseline heartrate which is measurable • Uses Spark Analytics to determine baseline heartrates and plots the trend (heartrate rising, steady, or falling) • Graphing tools in browser show us a view of the data
