What is an LSM-Tree and How Does it Handle Writes?
A Log-Structured Merge-tree (LSM-tree) is a storage engine design that turns random writes into fast sequential appends by first buffering writes in an in-memo…
What is Write Amplification and Why Does it Matter?
Write amplification is the ratio between the amount of data actually written to physical storage and the amount of data the application logically intended to w…
SSD Scheduling Considerations vs Hard Disks
Because SSDs have no moving read/write head, seek-minimizing algorithms like SCAN or SSTF give little benefit and can even hurt performance, so OS I/O schedule…
What is Database Indexing at Scale?
Database indexing at scale is the practice of building auxiliary data structures, typically B-trees or hash indexes, that let queries locate rows without scann…
What is Write Amplification and Why Does It Matter for Storage Engines?
Write amplification is the phenomenon where a single logical write from an application triggers a much larger amount of physical data actually written to durab…
What is a Log-Structured Merge (LSM) Tree?
A log-structured merge (LSM) tree is a write-optimized storage data structure that buffers writes in an in-memory sorted table and periodically flushes them as…
B-Tree vs LSM-Tree Storage: Which Should You Choose?
B-trees update data in place with balanced, sorted disk pages that favor fast, low-amplification reads, while LSM-trees buffer writes in memory and flush them…
