A high performance / realtime C++17 stream-processing framework with avro support. The design is influenced by apache kafka streams library. Change data capture for a postgres and sql server. Export to kafka, mqtt, postgres, elastic search, influxdb and avrofiles


  • kafka (uses librdkafka)
  • kafka grpc proxy
  • aws kinesis (experimental, using aws sdk)
  • postgres (uses libpq)
  • microsoft sqlserver (uses freetds)
  • memory stream

Offset storage:

  • kafka
  • file
  • S3 (uses aws sdk)


  • kafka (using librdkafka)
  • mqtt (using paho libraries)
  • postgres (uses libpq)
  • influxdb
  • elastic search
  • files (avro)
  • S3 (avro)
  • memory stream


  • rocksdb
  • memory


  • avro (with confluent schema registry or grpc proxy)
  • text
  • json


  • prometheus

It is intended to be run in kubernetes but works equally well standalone

Platforms: Linux (Windows and Mac build are outdated)

Ubuntu 18.04 x64:

Remove stuff that you should not have...

sudo apt-get purge libprotobuf-dev libgrpc++-dev protobuf-compiler
sudo apt-get purge openssl-dev

Install build tools

sudo apt-get install -y software-properties-common
sudo apt-get update
sudo apt-get install -y g++ sudo pax-utils automake autogen shtool libtool git wget cmake unzip build-essential pkg-config sed bison flex

Install build deps

sudo apt-get install -y python-dev autotools-dev libicu-dev zlib1g-dev openssl libssl-dev libbz2-dev libsnappy-dev liblz4-dev libzstd-dev \

install 3rd party deps we need to build from source (you can hack versions - see the file)
