Fulcrum

Distributed Ultra Scalable Database

Staying on shoulders of Giants:

• Best in Breed storage
• Best in Breed netwoking
• Fit for purpose modern languages
• Proven big blocks, no reinvented bycicles

Plans

• Grpc for remoting
• Client-side load balancing
• TLS enabled communication
• Authentication
  • OAuth
  • NTLM
  • Kerberos
• Protobuf .proto files for stored data
• Flatbufs for stored data (as per Apache Arrow)
• Async Rust server
• Native clients for
  • Rust
  • .Net
  • Java/Kotlin
  • Javascript
• sled, as embedded storage (millions/sec reads/writes for short data)
• Special treatment for long keys
• Special treatment for long value
  • Zero-cost value cloning
  • Long values partitioning
• CDN-like LRU cache-through servers for value parts
• Server replication via Raft and Reliable Casual Broadcast (with CRDT)
  • Reimplement RCB from https://github.com/cotyar/braindump in Rust
  • Sync-free Primitives and partitioning resistence similar to AntidotDB
• Merkle-tree-based data consistency
• "soft-delete"
• keys TTL (expirations)
• Orleans inspired distributed transactions (aka external ACID)
• RavenDB-inspired automated index management
• ACL-based authorizations
  • LDAP3 integration (Active Directory, etc)
• Column-oriented indices
• Regex indices
• Full-text search
• ActorDB inspired multi-island sharding
• Automatic query optimisation
• Remote logging and instrumentation
  • tokio-tracing
  • Opentracing
• Write auto batching
• Persistent Subscriptions
• Value compression
• Value encryption
• Externaly consistent SQL
• WebAssembly-based stored procedures (somewhat inspired by EOS)
