Practical overview

When it fits

Use it when Solana data needs to enter an Apache Kafka pipeline from a self-hosted validator/plugin environment, with either broad event publishing or configured program and account filters.

Who it is for

  • Solana validator and plugin operators
  • Engineers building Kafka-based blockchain data pipelines
  • Teams developing Solana monitoring, indexing or analytics systems

Documented uses

  • Stream Solana account changes into Kafka.
  • Publish complete transaction details, including instructions, fees and success or failure.
  • Track slot progress, confirmation status and health-related slot events.
  • Feed Solana data into monitoring, indexing, analytics or warehouse pipelines.
Before you choose

Requirements & limits

The repository is public and lists an Apache-2.0 license. The project is described for Linux, server and self-hosted environments. No pricing or account requirement is documented.

  • Kafka is required as the event destination through the configured bootstrap servers and topics.
  • Account and transaction events use whitelist filtering unless all accounts are enabled; slot-status events are not affected by filters.
  • The plugin must be built against the same Solana and Rust versions as the validator.
  • Source builds require Rust 1.93.1 and Protobuf 3.15 or later.
  • The configuration can control topics, ignored programs or accounts, failed and vote transactions, message wrapping, producer buffering and optional Prometheus metrics.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Build the Kafka plugin from source

Produce the plugin library for use with a Solana validator and Kafka configuration.

Before you start

  • Rust 1.93.1, as specified by the repository toolchain.
  • Protobuf compiler version 3.15 or later.
  • A build environment identical to the Solana validator environment, including Solana and Rust versions.

Steps

  1. Install the documented Rust toolchain and a compatible Protobuf compiler.

  2. Run the command below.

    Documented command
    cargo build --release

  3. Use the generated Linux library at ./target/release/libsolana_accountsdb_plugin_kafka.so or the macOS library at ./target/release/libsolana_accountsdb_plugin_kafka.dylib.

  4. Reference the library path in the plugin JSON configuration.

Expected outcome

A release-built plugin library is available to reference from the Solana plugin configuration.

Guide limitations

  • The documented build requires matching validator and plugin build environments; mismatched Solana or Rust versions can cause memory corruption and crashes.
  • The guide documents compilation and library paths, not validator deployment or a successful runtime test.
