From 930aeb9c90730b1b661f8571d13d67a4bbf063e4 Mon Sep 17 00:00:00 2001 From: jonathanmagambo Date: Sat, 7 Mar 2026 20:31:11 -0500 Subject: [PATCH 1/2] feat(storage/query): implement secondary indexes and safe joins - Added `extract_field_raw` for zero-allocation MessagePack field extraction. - Introduced `IndexRegistry` to natively manage secondary indexes. - Wired atomic MVCC index updates during `insert`, `update_doc`, and `delete`. - Flattened pagination params to handle dynamic `where[field]` intercept routing. - Implemented `POST /v1/_query` relational BFS executor with N+1 B-Tree traversals. - Designed `JoinQuery` AST in `forge-types` enforcing max depth caps. --- Cargo.lock | 3 + crates/server/src/lib.rs | 204 ++++++++++++++++++- crates/storage/Cargo.toml | 2 + crates/storage/src/engine.rs | 351 ++++++++++++++++++++++++++++++++- crates/storage/src/extract.rs | 254 ++++++++++++++++++++++++ crates/storage/src/index.rs | 132 +++++++++++++ crates/storage/src/lib.rs | 3 + crates/types/Cargo.toml | 1 + crates/types/src/lib.rs | 2 + crates/types/src/pagination.rs | 7 + crates/types/src/query.rs | 151 ++++++++++++++ 11 files changed, 1092 insertions(+), 18 deletions(-) create mode 100644 crates/storage/src/extract.rs create mode 100644 crates/storage/src/index.rs create mode 100644 crates/types/src/query.rs diff --git a/Cargo.lock b/Cargo.lock index 676bfda..24c238f 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -819,8 +819,10 @@ dependencies = [ "bytes", "forge-types", "redbx", + "rmp", "rmp-serde", "serde", + "serde_json", "tempfile", "tokio", "tracing", @@ -833,6 +835,7 @@ version = "0.2.0" dependencies = [ "redbx", "serde", + "serde_json", "thiserror 2.0.18", "toml", "uuid", diff --git a/crates/server/src/lib.rs b/crates/server/src/lib.rs index f1dcf74..765f0bf 100644 --- a/crates/server/src/lib.rs +++ b/crates/server/src/lib.rs @@ -68,7 +68,15 @@ pub fn app(state: AppState) -> Router { "/v1/{collection}/{id}", get(get_doc).patch(update_doc).delete(delete_doc), ) - .route("/v1/_query", axum::routing::post(query_docs_stub)) + .route( + "/v1/_indexes/{collection}", + axum::routing::post(create_index), + ) + .route( + "/v1/_indexes/{collection}/{field}", + axum::routing::delete(drop_index), + ) + .route("/v1/_query", axum::routing::post(query_docs)) // Everything inside /v1 requires a valid PASETO token. // The middleware parses the Bearer header and rejects bad tokens fast. .route_layer(axum::middleware::from_fn_with_state( @@ -128,7 +136,32 @@ async fn list_docs( let limit = params.limit.unwrap_or(50).clamp(1, 100) as usize;
