High Performance

QuantaDB is designed from the ground up for exceptional performance, making it a leading choice for demanding local data storage needs in Dart and Flutter applications.

At the core of QuantaDB's speed is its Log-Structured Merge Tree (LSM-Tree) based storage engine. Unlike traditional B-tree databases that perform in-place updates, LSM-Trees append data to sequential logs. This design offers significant advantages for write-heavy workloads:

• Optimized Writes: Sequential writes are generally much faster than random writes, reducing disk I/O overhead.
• Reduced Write Amplification: Data is written in larger, sequential blocks.
• Efficient Reads (with optimizations): While basic reads might require checking multiple levels of sorted data, QuantaDB employs optimizations like Bloom Filters and MemTables to quickly locate data, minimizing the need to read from disk.

The LSM-Tree architecture, combined with careful optimization in pure Dart, allows QuantaDB to achieve superior performance for both read and write operations, as demonstrated by the performance benchmarks.
