FlashDB is an ultra-lightweight embedded database that focuses on providing data storage solutions for embedded products. Different from traditional database based on file system, FlashDB combines the features of Flash and has strong performance and reliability. And under the premise of ensuring extremely low resource occupation, the service life of Flash should be extended as much as possible.
FlashDB provides two database modes:
Nowadays, there are more and more types of IoT products, and the types and total amount of data generated during operation are also increasing. FlashDB provides a variety of data storage solutions, not only has a small resource footprint, but also has a large storage capacity, which is very suitable for IoT products. The following are the main application scenarios:
msh />tsl bench Append 1250 TSL in 5 seconds, average: 250.00 tsl/S, 4.00 ms/per Query total spent 2218 (ms) for 1251 TSL, min 1, max 2, average: 1.77 ms/per
Insert average: 4 ms, query average: 1.8 ms
msh />tsl bench Append 13421 TSL in 5 seconds, average: 2684.20 tsl/S, 0.37 ms/per Query total spent 1475 (ms) for 13422 TSL, min 0, max 1, average: 0.11 ms/per
Insert average: 0.37 ms, query average: 0.12 ms
