Install steps

Build

JDK 1.8 (JDK 1.9+ are not supported yet)

   cd java-tron
   ./gradlew build

Run full node and support sending messages to Kafka

    cd build/libs
    java -jar FullNode.jar -c your config.conf (Example：/data/java-tron/config.conf) -d <data directory>

add kafka.endpoint into config.conf, for example:

    kafka.endpoint = {
        url = "http://localhost:8082/topics/trx"
    }

Install confluent and kafka

Install kafka

See kafka

Modify config/server.properties

message.max.bytes=1048576000

Install confluent

see confluent

Unzip the confluent package and run Confluent REST Proxy

Modify /etc/kafka-rest/kafka-rest.properties

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

Install BDS

See BDS

Database

Database we now support SQL Server, PostgreSQL, you can choose one as a data storage method.

New funtion

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).
Sendblock and sendbatchblock are newly added as RPC interfaces to trigger full node to send data for a specific block.
