Kdb+ developers often find themselves working with some of the largest and most important real-time and historical data sets in the world. Managing such data sets can involve consuming feeds from multiple sources in parallel, performing in-memory analysis, and storing data on disk for future reference.
In the latest in our ongoing series of kdb+ technical white papers published on the KX Developer’s site, KX engineer Paula Clarke has written about the sym file, a key component of kdb+ application architecture.
In this whitepaper, Paula discusses what the sym file is and gives suggestions for table setup, the maintenance of the sym file and safety measures that can be taken to protect the sym file.
