feat(connectors): add SurrealDB sink connector by countradooku · Pull Request #3453 · apache/iggy

countradooku · 2026-06-11T08:48:26Z

Summary

Adds a SurrealDB sink connector for writing Iggy messages into SurrealDB over the HTTP API via reqwest.

The connector supports deterministic record IDs, bulk INSERT IGNORE writes for idempotent replay, configurable batch sizing, root/namespace/database/no-auth modes, optional table and offset-index definition, payload modes (auto, json, text, base64/binary), metadata/header/checksum/origin timestamp fields, retry/backoff handling, and runtime metrics logging.

This PR does not depend on the SurrealDB Rust SDK. The v3.1.4 reference is only the Docker image tag used by the integration-test fixture, so the earlier SurrealDB SDK BUSL licensing concern is not applicable to this connector.

It also wires the connector into workspace membership, connector docs, binary artifact builds, edge-release output, version bump scripts, and Docker-backed integration test scaffolding.

Tests

cargo fmt --all
cargo test -p iggy_connector_surrealdb_sink
cargo clippy -p iggy_connector_surrealdb_sink --all-targets -- -D warnings
cargo test -p integration --no-run
cargo build -p iggy_connector_surrealdb_sink
cargo test -p integration -- connectors::surrealdb::surrealdb_sink
cargo sort --no-format --workspace --check
./scripts/ci/taplo.sh --check
git diff --check

./scripts/ci/markdownlint.sh could not be run locally because markdownlint is not installed in this shell.

SurrealDB is a document database target for Iggy connector users, so the sink writes batches with deterministic record ids and bulk INSERT IGNORE to keep runtime redelivery idempotent without per-message round trips. Constraint: User explicitly requested the latest SurrealDB Rust SDK and chose to keep it despite BUSL-1.1 license-validation warnings for SurrealDB crates. Constraint: Local Docker daemon was unavailable, so real-container integration execution could not run here. Rejected: Per-message SDK writes | too many round trips and weaker batching throughput. Rejected: Using the testcontainers SurrealDB module | module source hardcodes an older SurrealDB image. Confidence: medium Scope-risk: moderate Directive: Keep record ids deterministic across releases; changing build_record_id breaks replay idempotency. Tested: cargo fmt --all; cargo sort --no-format --workspace; cargo clippy --all-features --all-targets -- -D warnings; cargo check --all --all-features; cargo test -p iggy_connector_surrealdb_sink; cargo test -p integration --no-run connectors::surrealdb; cargo test --locked --doc; cargo doc --no-deps --all-features --quiet; taplo/license/shellcheck/version/diff/binary checks; prek install Not-tested: Docker-backed SurrealDB integration execution, because Docker daemon was not running locally.

Sure

HawkEye maps Rust files to the double-slash license style, so the block comments in the new SurrealDB connector files were treated as missing headers by CI. Constraint: CI runs the updated HawkEye-based license check with strict header matching.

The Rust pre-merge machete job reported that the SurrealDB sink crate declared toml without using it. Removing the dev-dependency is simpler than adding an ignore entry. Constraint: CI runs cargo machete --with-metadata and fails on unused dependencies. Rejected: Add cargo-machete metadata ignore | the dependency is genuinely unused.

how much time do the newly added tests take, on your machine?

countradooku · 2026-06-24T15:28:47Z

On my machine, the focused SurrealDB integration test filter:
cargo test -p integration -- connectors::surrealdb::surrealdb_sink
runs 4 tests in 1.94s test time, 11.57s wall-clock including incremental compile.
The SurrealDB sink unit tests:
cargo test -p iggy_connector_surrealdb_sink
run 35 tests in 0.02s test time, 0.61s wall-clock.

a few non-line notes:

the description says this uses the surrealdb rust sdk 3.1.4 and flags BUSL-1.1 license failures from surrealdb sdk crates, but the code uses raw reqwest and the lockfile adds no surrealdb crate. 3.1.4 is the test-container image tag, not a dep, so the BUSL concern is moot. please fix the description and drop that item.
the jwt default crypto-provider install (under core/server/src/http/jwt + the a2a_jwt tests) and the cpp-bazel cargo registry retries look unrelated to the surrealdb sink. if the jwt change is a rustls feature-unification fix triggered by linking the sink into the all-crates build, please say so; otherwise split these out.
no adversarial round-trip test for the query builder (quotes/brackets in payloads and identifiers). it's safe by construction - identifiers are validated and bodies go through serde_json escaping - but a test would lock that in.
