SaaS Insight for Building a Real time CRM ApplicationBackgroundTo store large volumes of real time user data like email and provide insights is not easy If your application is layered on top of Gmail to automatically extract and organize the useful information buried inside of our inboxes It became clear that they were going to need a better system for organizing terabytes of email metadata to power collaboration as their customer base rapidly increased it is not easy to provide insights You need to organize email data by first applying a unique identifier to the emails and then proactively indexing the email metadata The unique identifier is what connects the same email headers across For each email inserted in real time the system extracts meta information from it and builds indices for high concurrent access When data volume is small it s all good traditional databases provide all you need However when data size grows beyond a single node s capacity everything becomes very hard Potential Database SolutionsRegarding databases there are some options you might consider NoSQL database While fairly scalable it does not provide you indexing and comprehensive query abilities You might end up implementing them in your application code Sharing cluster of databases Designing sharding key and paying attention to the limitations between shards are painful It might be fine for applications with simple schema designs but it will be too complicated for CRM Moreover it s very hard to maintain Analytical databases They are fine for dashboard and reporting But not fine for high concurrent updates and index based serving How to get real time insightsTiDB is a distributed database with user experience of traditional databases It looks like a super large MySQL without the limitations of NoSQL and sharding cluster solutions With TiDB you can simply have the base information indices and metadata being updated in a concurrent manner with the help of cross node transaction ability To build such a system you just need following steps Create schemas according to your access pattern with indices on user name organization job title etc Use streaming system to gather and extract meta information from your base dataInsert into TiDB via ordinary MySQL client driver like JDBC You might want to gather data in small batches of hundreds of rows to speed up ingestion In a single transaction updates on base data indices and meta information are guaranteed to be consistent Optionally deploy a couple of TiFlash nodes to speed up large scale reporting queries Access the data just like in MySQL and you are all done SQL features for analytics like aggregations multi joins or window functions are all supported with great performance For more cases please see here |
