8 Key Data Structures That Power Modern Databases:
- Skiplist: a common in-memory index type. Used in Redis
- Hash index: a very common implementation of the “Map” data structure (or “Collection”)
- SSTable: immutable on-disk “Map” implementation
- LSM tree: Skiplist + SSTable. High write throughput
- B-tree: disk-based solution. Consistent read/write performance
- Inverted index: used for document indexing. Used in Lucene
- Suffix tree: for string pattern search
- R-tree: multi-dimension search, such as finding the nearest neighbor
