Sorry for beginner question, but I was wondering how is data and indexes stored in voltdb? I've read a lot of documentation and papers from voltdb about how tables are partitioned and replicated and stored at the high level, but how does VoltDB handle the storage efficiently in code/backend and how is it stored in the memory?
I've read Which data structures are used in voltdb but was wondering if some one can point me in the direction of where this is handled in the voltdb codebase? Thanks alot.
I work at VoltDB. The data is stored in main memory (but not on the java heap. It is in data structures that are allocated and used independently by the C++ execution engines. The relevant code is in the src/ee subdirectory.
