Task Example

Simple:

The following example is for a Kudu table named "kudu_source_table", The goal is to print the data from this table on the console and write kudu table "kudu_sink_table"

# Defining the runtime environment
env {
parallelism = 2
job.mode = "BATCH"
}

source {
# This is a example source plugin **only for test and demonstrate the feature source plugin**
kudu {
kudu_masters = "kudu-master:7051"
table_name = "kudu_source_table"
result_table_name = "kudu"
enable_kerberos = true
kerberos_principal = "xx@xx.COM"
kerberos_keytab = "xx.keytab"
}
}

transform {
}

sink {
console {
source_table_name = "kudu"
}

kudu {
source_table_name = "kudu"
kudu_masters = "kudu-master:7051"
table_name = "kudu_sink_table"
enable_kerberos = true
kerberos_principal = "xx@xx.COM"
kerberos_keytab = "xx.keytab"
}
}

Multiple Table

env {
# You can set engine configuration here
parallelism = 1
job.mode = "STREAMING"
checkpoint.interval = 5000
}

source {
# This is a example source plugin **only for test and demonstrate the feature source plugin**
kudu{
kudu_masters = "kudu-master:7051"
table_list = [
{
table_name = "kudu_source_table_1"
},{
table_name = "kudu_source_table_2"
}
]
result_table_name = "kudu"
}
}

transform {
}

sink {
Assert {
rules {
table-names = ["kudu_source_table_1", "kudu_source_table_2"]
}
}
}
