From 749613f61948e9f4c3b5380fa0fcfad26e47c6d1 Mon Sep 17 00:00:00 2001 From: ryerraguntla Date: Mon, 9 Mar 2026 14:50:45 -0400 Subject: [PATCH 01/29] Add InfluxDB source and sink example configs Add example TOML configuration files for InfluxDB source and sink connectors under core/connectors/runtime/example_config/connectors/influx. Each file includes connector metadata (type, key, name, path, plugin format) and stream/plugin_config sections. The sink config defines connection (url, org, bucket, token), measurement/precision, payload and metadata/tag options, batching, retries and timeouts. The source config provides connection and token, a Flux query template using $cursor and $limit, polling, batch/cursor settings, initial offset, and retry/timeout settings. These serve as runtime examples for connector development and testing. --- .../connectors/influx/influxdb_sink.toml | 52 ++++++++++++++++++ .../connectors/influx/influxdb_source.toml | 53 +++++++++++++++++++ 2 files changed, 105 insertions(+) create mode 100644 core/connectors/runtime/example_config/connectors/influx/influxdb_sink.toml create mode 100644 core/connectors/runtime/example_config/connectors/influx/influxdb_source.toml diff --git a/core/connectors/runtime/example_config/connectors/influx/influxdb_sink.toml b/core/connectors/runtime/example_config/connectors/influx/influxdb_sink.toml new file mode 100644 index 0000000000..b7d407f316 --- /dev/null +++ b/core/connectors/runtime/example_config/connectors/influx/influxdb_sink.toml @@ -0,0 +1,52 @@ +# Licensed to the Apache Software Foundation (ASF) under one +# or more contributor license agreements.

Adds exponential backoff with ±20% jitter for open/poll/write retries, honours Retry-After on HTTP 429, and caps backoff delays. Introduces a simple consecutive-failure circuit breaker (threshold + cool-down) to avoid hammering unavailable InfluxDB instances and new config fields (max_open_retries, open_retry_max_delay, circuit_breaker_threshold, circuit_breaker_cool_down). Sink now propagates batch write errors (preventing silent data loss) and resets/records circuit state on success/failure. Consolidates helper functions (duration parsing, backoff, jitter, retry-after parsing, escaping), minor logging improvements, and type fixes. Adds integration test scaffolding for InfluxDB (docker-compose, sink/source tests) and updates connector Cargo.toml entries (rand/workspace and small feature tweaks in integration Cargo.toml). --- Cargo.lock | 26 + .../connectors/sinks/influxdb_sink/src/lib.rs | 771 +++++++++++++++++ core/connectors/sinks/mongodb_sink/Cargo.toml | 3 + .../sources/influxdb_source/Cargo.toml | 54 ++ .../sources/influxdb_source/src/lib.rs | 808 ++++++++++++++++++ core/integration/Cargo.toml | 6 +- .../connectors/influxdb/docker-compose.yml | 77 ++ .../connectors/influxdb/influxdb_sink.rs | 536 ++++++++++++ .../connectors/influxdb/influxdb_source.rs | 601 +++++++++++++ .../tests/connectors/influxdb/mod.rs | 24 + .../tests/connectors/influxdb/test_utils.rs | 179 ++++ core/integration/tests/connectors/mod.rs | 1 + 12 files changed, 3083 insertions(+), 3 deletions(-) create mode 100644 core/connectors/sinks/influxdb_sink/src/lib.rs create mode 100644 core/connectors/sources/influxdb_source/Cargo.toml create mode 100644 core/connectors/sources/influxdb_source/src/lib.rs create mode 100644 core/integration/tests/connectors/influxdb/docker-compose.yml create mode 100644 core/integration/tests/connectors/influxdb/influxdb_sink.rs create mode 100644 core/integration/tests/connectors/influxdb/influxdb_source.rs create mode 100644 core/integration/tests/connectors/influxdb/mod.rs create mode 100644 core/integration/tests/connectors/influxdb/test_utils.rs diff --git a/Cargo.lock b/Cargo.lock index 6f4d7aa024..3ce93eb9d8 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -5441,10 +5441,36 @@ dependencies = [ "humantime", "iggy_connector_sdk", "mongodb", + "once_cell", + "rand 0.9.2", + "reqwest", + "serde", + "serde_json", + "tokio", + "tracing", +] + +[[package]] +name = "iggy_connector_influxdb_source" +version = "0.2.2-edge.1" +dependencies = [ + "async-trait", + "base64 0.22.1", + "csv", + "dashmap", + "futures", + "humantime", + "iggy_common", + "iggy_connector_influxdb_sink", + "iggy_connector_sdk", + "once_cell", + "rand 0.9.2", + "reqwest", "serde", "serde_json", "tokio", "tracing", + "uuid", ] [[package]] diff --git a/core/connectors/sinks/influxdb_sink/src/lib.rs b/core/connectors/sinks/influxdb_sink/src/lib.rs new file mode 100644 index 0000000000..c89ae740ba --- /dev/null +++ b/core/connectors/sinks/influxdb_sink/src/lib.rs @@ -0,0 +1,771 @@ +/* Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.

Fix source polling to avoid unconditional sleep and to sleep when circuit breaker is open.

Enhance InfluxDB sink implementation with robust retry behavior: true exponential backoff, jitter, honoring Retry-After, connectivity retries on open, a circuit breaker for consecutive failures, propagation of batch errors, and releasing the HTTP client on close. Update SDK error enum with value-specific variants. Update source/sink code to use updated rand APIs and adjust integration tests/fixtures (Flux queries, assertions, and logging). Tidy Cargo.toml entries (remove unused deps from mongodb sink) and update Cargo.lock to include csv, csv-core and connector package metadata. These changes aim to improve connector reliability and test coverage. --- Cargo.lock | 65 ++++++++++++++++- Cargo.toml | 3 + core/connectors/sdk/src/lib.rs | 4 + .../connectors/sinks/influxdb_sink/src/lib.rs | 73 +++++++------------ core/connectors/sinks/mongodb_sink/Cargo.toml | 3 -
