From 78c226a0985ec3143f8393ac72a71996ee4b165f Mon Sep 17 00:00:00 2001 From: Gulshan Yadav Date: Sat, 10 Jan 2026 17:40:18 +0530 Subject: [PATCH] feat(database): add Phase 10 Synor Database L2 foundation Multi-model database layer for Synor blockchain: - Key-Value Store: Redis-compatible API with TTL, INCR, MGET/MSET - Document Store: MongoDB-compatible queries with filters - Vector Store: AI/RAG optimized with cosine, euclidean, dot product similarity - Time-Series Store: Metrics with downsampling and aggregations - Query Engine: Unified queries across all data models - Index Manager: B-tree, hash, unique, and compound indexes - Schema Validator: Field validation with type checking - Database Pricing: Pay-per-use model (0.1 SYNOR/GB/month) Updates roadmap with Phase 10-12 milestones: - Phase 10: Synor Database L2 - Phase 11: Economics & Billing - Phase 12: Fiat Gateway (Ramp Network integration) 41 tests passing --- Cargo.toml | 1 + crates/synor-database/Cargo.toml | 39 ++ crates/synor-database/src/document.rs | 621 ++++++++++++++++++++++++ crates/synor-database/src/error.rs | 64 +++ crates/synor-database/src/index.rs | 522 ++++++++++++++++++++ crates/synor-database/src/keyvalue.rs | 442 +++++++++++++++++ crates/synor-database/src/lib.rs | 436 +++++++++++++++++ crates/synor-database/src/query.rs | 570 ++++++++++++++++++++++ crates/synor-database/src/schema.rs | 336 +++++++++++++ crates/synor-database/src/timeseries.rs | 534 ++++++++++++++++++++ crates/synor-database/src/vector.rs | 494 +++++++++++++++++++ docs/PLAN/README.md | 126 +++++ 12 files changed, 4185 insertions(+) create mode 100644 crates/synor-database/Cargo.toml create mode 100644 crates/synor-database/src/document.rs create mode 100644 crates/synor-database/src/error.rs create mode 100644 crates/synor-database/src/index.rs create mode 100644 crates/synor-database/src/keyvalue.rs create mode 100644 crates/synor-database/src/lib.rs create mode 100644 crates/synor-database/src/query.rs create mode 100644 crates/synor-database/src/schema.rs create mode 100644 crates/synor-database/src/timeseries.rs create mode 100644 crates/synor-database/src/vector.rs diff --git a/Cargo.toml b/Cargo.toml index 0f57bcf..a9b8da5 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -8,6 +8,7 @@ members = [ "crates/synor-network", "crates/synor-storage", "crates/synor-hosting", + "crates/synor-database", "crates/synor-governance", "crates/synor-rpc", "crates/synor-vm", diff --git a/crates/synor-database/Cargo.toml b/crates/synor-database/Cargo.toml new file mode 100644 index 0000000..15b7c94 --- /dev/null +++ b/crates/synor-database/Cargo.toml @@ -0,0 +1,39 @@ +[package] +name = "synor-database" +version.workspace = true +edition.workspace = true +description = "Multi-model database layer for Synor blockchain" +license.workspace = true + +[dependencies] +# Internal crates +synor-types = { path = "../synor-types" } +synor-crypto = { path = "../synor-crypto" } +synor-storage = { path = "../synor-storage" } + +# Serialization +serde.workspace = true +serde_json.workspace = true +borsh.workspace = true + +# Utilities +thiserror.workspace = true +parking_lot.workspace = true +tracing.workspace = true +hex.workspace = true + +# Hashing +blake3.workspace = true + +# Async +tokio = { workspace = true, features = ["sync", "rt-multi-thread"] } + +# Data structures +lru = "0.12" +indexmap = "2.2" + +# Vector operations (for AI/RAG) +# Using pure Rust for portability + +[dev-dependencies] +tempfile.workspace = true diff --git a/crates/synor-database/src/document.rs b/crates/synor-database/src/document.rs new file mode 100644 index 0000000..e5d198d --- /dev/null +++ b/crates/synor-database/src/document.rs @@ -0,0 +1,621 @@ +//!
