Task Example

Simple:

The following example refers to a FakeSource named "kudu" cdc write kudu table "kudu_sink_table"


env {
parallelism = 1
job.mode = "BATCH"
}
source {
FakeSource {
result_table_name = "kudu"
schema = {
fields {
id = int
val_bool = boolean
val_int8 = tinyint
val_int16 = smallint
val_int32 = int
val_int64 = bigint
val_float = float
val_double = double
val_decimal = "decimal(16, 1)"
val_string = string
val_unixtime_micros = timestamp
}
}
rows = [
{
kind = INSERT
fields = [1, true, 1, 2, 3, 4, 4.3,5.3,6.3, "NEW", "2020-02-02T02:02:02"]
},

}
}
