The Canary Historian is a non-SQL, proprietary database that specializes in the storage and retrieval of time-series process data using “lossless” compression. Unlike other historians, Canary never converts actual data to approximations. Also, the historian never purges or dumps data and resolution remains the same whether the data is one day or several decades old.
The historian is capable of write speeds up to 2,800,000 TVQs per second and can support sub-second data with a timestamp resolution of 100 nanoseconds. Manual data entry is also supported and can be done directly into the historian. Read retrieval speeds approach 4,600,000 TVQs per second and due to the time-based database structure allow for effortless data recall even when spanning large timeframes.
