1. Apple FoundationDB A Database To Rule Them All Amirouche BOUBEKKI @ 2018/08/31
2. • data expert system = database • space vs time • read vs write • indexing • structure vs query language • operations
3. History & Ecosystem - MySQL / PostgreSQL / Oracle / MSSQL / IBM DB2 / sqlite - Big Data / NoSQL - HBase / Cassandra (CQL) / Riak / MongoDB / CouchDB / DynamoDB / REDIS / ElasticSearch - dbm, bsddb, Kyoto Cabinet, LMDB, LevelDB, RocksDB, WiredTiger - Google Spanner, CockroachDB, TiDB & FoundationDB
4. Atomic Consistent Isolated Durable https://apple.github.io/foundationdb/transaction-manifesto.html
5. Consistent A read sees all previously completed writes. Availability Reads and writes always succeed. Partition Guaranteed properties are maintained even when network failures prevent some machines from communicating with others. https://apple.github.io/foundationdb/cap-theorem.html
6. Features - Scalable - ACID transactions - Fault tolerance - Replicated Storage - Ordered Key-Value API - Watches - Atomic Operations - OLTP / OLAP https://apple.github.io/foundationdb/features.htm l
7. Anti-features - Data models - Query languages - Analytic frameworks - Disconnected operation - Long-running read/write transactions https://apple.github.io/foundationdb/anti-features.html
8. Known Limitations https://apple.github.io/foundationdb/known-limitations.html
9. FDB vs PostgreSQL - Similar guarantees - Directory instead of tables - Indices are built by layers / applications - Watches instead notify / triggers - Layers instead extensions - Scalability / Distributed Fault Tolerance
10. FDB vs ElasticSearch - Stronger guarantees - Key-Value instead of Document - Indices are built by layers / applications - No map / reduce
11. FDB vs REDIS - Stronger guarantees - Ordered key space - Disk based
12. FDB vs MongoDB 3.4 - Stronger guarantees - Key-Value instead of Document - Indices are built by layers / applications - No map / reduce
