From 65c041637609d55302e80a8e850da680cb33dbcc Mon Sep 17 00:00:00 2001 From: Avi Avni Date: Sun, 12 Apr 2026 16:05:51 +0300 Subject: [PATCH 01/38] Implement RDB serialization and deserialization for graph data - Added `decoder/mod.rs` to handle loading graphs from RDB streams, supporting both single-key and multi-key formats. - Implemented `rdb_load_graph` function to decode graph headers, schemas, and payloads, managing pending graphs for multi-key scenarios. - Introduced `encoder/mod.rs` for encoding graphs into RDB format, including functions for single-key and multi-key payload distribution. - Created `mod.rs` to manage serialization modules, including global states for virtual key management and decoding. - Updated tests in `test_persistency.py` and `test_replication.py` to reflect changes in index creation syntax and ensure compatibility with new serialization methods. --- Cargo.lock | 2 + Cargo.toml | 2 + flow.sh | 4 +- flow_tests_done.txt | 2 + flow_tests_todo.txt | 2 - graph/src/graph/attribute_store.rs | 117 ++- graph/src/graph/graph.rs | 291 ++++++- graph/src/graph/graphblas/matrix.rs | 126 ++- graph/src/graph/graphblas/mod.rs | 1 + graph/src/graph/graphblas/serialization.rs | 213 +++++ graph/src/graph/graphblas/tensor.rs | 81 +- graph/src/graph/graphblas/vector.rs | 229 ++++- graph/src/graph/graphblas/versioned_matrix.rs | 54 +- graph/src/graph/mvcc_graph.rs | 10 + graph/src/index/indexer.rs | 12 + graph/src/runtime/pending.rs | 13 +- graph/src/runtime/value.rs | 138 ++- src/graph_core.rs | 12 + src/lib.rs | 5 +- src/module_init.rs | 13 + src/redis_type.rs | 803 ++++++++++++++++-- src/serializers/buffered_io.rs | 310 +++++++ src/serializers/decoder/mod.rs | 333 ++++++++ src/serializers/encoder/mod.rs | 213 +++++ src/serializers/mod.rs | 559 ++++++++++++ tests/flow/test_persistency.py | 14 +- tests/flow/test_replication.py | 2 +- 27 files changed, 3418 insertions(+), 143 deletions(-) create mode 100644 graph/src/graph/graphblas/serialization.rs create mode 100644 src/serializers/buffered_io.rs create mode 100644 src/serializers/decoder/mod.rs create mode 100644 src/serializers/encoder/mod.rs create mode 100644 src/serializers/mod.rs diff --git a/Cargo.lock b/Cargo.lock index 47bc2ddc..c3584c1a 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -394,7 +394,9 @@ dependencies = [ "parking_lot", "redis-module", "redis-module-macros", + "roaring", "ryu", + "thin-vec", ] [[package]] diff --git a/Cargo.toml b/Cargo.toml index 8a021999..3b88f2d1 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -28,7 +28,9 @@ graph = { path = "graph", version = "0.1.0" } lazy_static = "1.5.0" parking_lot = "0.12.5" redis-module = { git = "https://github.com/AviAvni/redismodule-rs", branch = "master" } +roaring = "0.11.3" ryu = "1.0.23" +thin-vec = "0.2.14" orx-tree = "2.2.0" [build-dependencies] diff --git a/flow.sh b/flow.sh index 3792cc78..816de50e 100755 --- a/flow.sh +++ b/flow.sh @@ -42,7 +42,7 @@ fi # TEST="tests/flow/test_function_calls" FAIL_FAST=1 ./flow.sh if [[ ${#TEST_FILTER[@]} -eq 0 ]];
