bds-bch is one of the independent modules in open source project of block chain data service (BDS) - provides full node service.

bds-bch Based on the v0.18.1 version of Bitcoin-ABC/bitcoin-abc,bds-bch redeveloped to support sending new block data directly to message middleware service of kafka to facilitate upstream services to subscribe and consume.

build-unix

1. Compile

  ./autogen.sh
  ./configure
  make
  make install # optional

2. Run full node and support sending messages to Kafka

    # log file position: <data_dir>/debug.log

   /usr/local/bin/bitcoind -kafka -kafkaproxyhost=<kafka proxy host> -kafkaproxyport=<kafka proxy port，default 8082> -kafkatopic=bch -datadir=<data directory> -rpcuser=<user> -rpcpassword=<password>

See kafka

• message.max.bytes=1048576000

see confluent

Unzip the confluent package and run Confluent REST Proxy

• max.request.size = 1048576000
• buffer.memory = 1048576000
• send.buffer.bytes = 1048576000

1. The new function of sending messages to Kafka is added（every time a new block is synchronized by full node, the data of the block is sent to kafka and the data structure is customized).
2. Sendblock and sendbatchblock are newly added as RPC interfaces to trigger full node to send data for a specific block.
