Task Example
Simple:
The following example describes writing multiple data types to SelectDBCloud, and users need to create corresponding tables downstream
env {
parallelism = 1
job.mode = "BATCH"
checkpoint.interval = 10000
}
source {
FakeSource {
row.num = 10
map.size = 10
array.size = 10
bytes.length = 10
string.length = 10
schema = {
fields {
c_map = "map<string, array<int>>"
c_array = "array<int>"
c_string = string
c_boolean = boolean
c_tinyint = tinyint
c_smallint = smallint
c_int = int
c_bigint = bigint
c_float = float
c_double = double
c_decimal = "decimal(16, 1)"
c_null = "null"
c_bytes = bytes
c_date = date
c_timestamp = timestamp
}
}
}
}
sink {
SelectDBCloud {
load-url = "warehouse_ip:http_port"
jdbc-url = "warehouse_ip:mysql_port"
cluster-name = "Cluster"
table.identifier = "test.test"
username = "admin"
password = "******"
selectdb.config {
file.type = "json"
}
}
}
Use JSON format to import data
sink {
SelectDBCloud {
load-url = "warehouse_ip:http_port"
jdbc-url = "warehouse_ip:mysql_port"
cluster-name = "Cluster"
table.identifier = "test.test"
username = "admin"
password = "******"
selectdb.config {
file.type = "json"
}
}
}
Use CSV format to import data
sink {
SelectDBCloud {
load-url = "warehouse_ip:http_port"
jdbc-url = "warehouse_ip:mysql_port"
cluster-name = "Cluster"
table.identifier = "test.test"
username = "admin"
password = "******"
selectdb.config {
file.type = "csv"
file.column_separator = ","
file.line_delimiter = "\n"
}
}
}
