How to Build

You need to copy customer_env.sh.tpl to customer_env.sh before build and you need to configure it before build.

git clone git@github.com:apache/doris-spark-connector.git
cd doris-spark-connector/spark-doris-connector
./build.sh

QuickStart

download and compile Spark Doris Connector from https://github.com/apache/doris-spark-connector, we suggest compile Spark Doris Connector by Doris official image。

$ docker pull apache/doris:build-env-ldb-toolchain-latest

the result of compile jar is like：spark-doris-connector-3.1_2.12-1.0.0-SNAPSHOT.jar
download spark for https://spark.apache.org/downloads.html .if in china there have a good choice of tencent link https://mirrors.cloud.tencent.com/apache/spark/spark-3.1.2/

#download
wget https://mirrors.cloud.tencent.com/apache/spark/spark-3.1.2/spark-3.1.2-bin-hadoop3.2.tgz
#decompression
tar -xzvf spark-3.1.2-bin-hadoop3.2.tgz

config Spark environment

vim /etc/profile
export SPARK_HOME=/your_parh/spark-3.1.2-bin-hadoop3.2
export PATH=$PATH:$SPARK_HOME/bin
source /etc/profile

copy spark-doris-connector-3.1_2.12-1.0.0-SNAPSHOT.jar to spark jars directory。

cp /your_path/spark-doris-connector/target/spark-doris-connector-3.1_2.12-1.0.0-SNAPSHOT.jar  $SPARK_HOME/jars

created doris database and table。

create database mongo_doris;
use mongo_doris;
CREATE TABLE data_sync_test_simple
 (
         _id VARCHAR(32) DEFAULT '',
         id VARCHAR(32) DEFAULT '',
         user_name VARCHAR(32) DEFAULT '',
         member_list VARCHAR(32) DEFAULT ''
 )
 DUPLICATE KEY(_id)
 DISTRIBUTED BY HASH(_id) BUCKETS 10
 PROPERTIES("replication_num" = "1");
INSERT INTO data_sync_test_simple VALUES ('1','1','alex','123');

Input this coed in spark-shell.

import org.apache.doris.spark._
val dorisSparkRDD = sc.dorisRDD(
  tableIdentifier = Some("mongo_doris.data_sync_test"),
  cfg = Some(Map(
    "doris.fenodes" -> "127.0.0.1:8030",
    "doris.request.auth.user" -> "root",
    "doris.request.auth.password" -> ""
  ))
)
dorisSparkRDD.collect()

mongo_doris:doris database name
data_sync_test:doris table mame.
doris.fenodes:doris FE IP:http_port
doris.request.auth.user:doris user name.
doris.request.auth.password:doris password

if Spark is Cluster model,upload Jar to HDFS，add doris-spark-connector jar HDFS URL in spark.yarn.jars.

spark.yarn.jars=hdfs:///spark-jars/doris-spark-connector-3.1.2-2.12-1.0.0.jar

Link：https://github.com/apache/doris/discussions/9486

in pyspark,input this code in pyspark shell command.

dorisSparkDF = spark.read.format("doris")
.option("doris.table.identifier", "mongo_doris.data_sync_test")
.option("doris.fenodes", "127.0.0.1:8030")
.option("user", "root")
.option("password", "")
.load()
# show 5 lines data 
dorisSparkDF.show(5)
