Big Objects in force.com platform

With Winter'14 salesforce introduced a feature called "Field History Retention". It was in pilot and with Spring'14 release, it's still in pilot. It is first force.com feature that uses big data technologies.


For more scalability, salesforce is working on big data technologies. And for this salesforce is working on new type of SObject 'Big Data'. Big objects are just like regular SObjects with more scalability, but less functionality.



Platform is built on top of relation technology using Oracle as main data repository for multi tenant environment. Now for more scalability salesforce is working on multi tenant big data store using HBase, which is open source database. Salesforce is working on Phoenix project, which allows to run low latency queries on top of HBase.



Initially Big Objects will come with let functionality and more scalability. When to use Big Object:-


  • if record count > 100 millions
  • can live with some platform limitations



In initial version following things will be difficult to do:-


  • Complex SOQL
  • Sharing
  • Isolated Transaction



We can expect following potential features in initial version:-


  • Flexible Schema
  • Powerful Data Processing
