This open-source database provides nearly-linear scalability and real-time querying predictability at the microsecond level.To achieve such higher availability it’s crucial to ensure that each release is thoroughly validated. Thousands of automated tests are run daily, for different versions and platforms to ensure defects are detected early and fixed. Testing is everyone’s ... Read More
