基于seatunnel-engine快速开始任务

第一步:部署seatunnel和插件

详解《seatunnel部署》

第二步:通过job定义文件编排任务

文件目录:config/v2.batch.config.template,下面是例子
env {
 execution.parallelism = 1
 job.mode = "BATCH"
}

source {
 FakeSource {
 result_table_name = "fake"
 row.num = 16
 schema = {
 fields {
 name = "string"
 age = "int"
 }
 }
 }
}

transform {
 FieldMapper {
 source_table_name = "fake"
 result_table_name = "fake1"
 field_mapper = {
 age = age
 name = new_name
 }
 }
}

sink {
 Console {
 source_table_name = "fake1"
 }
}

第三步:跑任务

cd "apache-seatunnel-${version}"
./bin/seatunnel.sh --config ./config/v2.batch.config.template -e local
