+# Byzer-Doris
+This extension enables Byzer-lang to read and write [Apache Doris](https://github.com/apache/doris)
+
+## Usage
+To read Doris table, use `load` statement. The following statement reads **Doris db**: zjc_1
+**table**: table_hash_1. 
+
+Please note: `doris.fenodes user password` are required
+```sql
+load doris.`zjc_1.table_hash_1`
+and `doris.fenodes`="127.0.0.1:8030"
+and `user`="user"
+and `password`="xxx"
+AS abc;
+```
+
+To insert into Doris table, use `save` statement:
+```sql
+SELECT 11 k1, 11.1 k2 , current_timestamp() dt AS data;
+
+SAVE append data AS doris.`zjc_1.table_hash_1`
+WHERE `doris.fenodes`="127.0.0.1:8030"
+and `user`="user"
+and `password`="xxx";
+```
+Please note that `overwrite` mode is not supported, `overwrite` is silently changed into
+`append` by [spark-doris-connector](https://github.com/apache/doris-spark-connector)
+
+To make your code clean, use `Connect` statement to setup common config. 
+The previous examples can be rewritten to:
+```sql
+CONNECT doris 
+WHERE `doris.fenodes`="127.0.0.1:8030"
+and `user`="user"
+and `password`="xxx"
+AS zjc_1;
+
+load doris.`zjc_1.table_hash_1` AS abc;
+
+SELECT 11 k1, 11.1 k2 , current_timestamp() dt AS data;
+
+SAVE append data AS doris.`zjc_1.table_hash_1`;
+```
+
+## Build
+To build this extension, please follow [spark-doris-connector document](https://doris.apache.org/zh-CN/docs/ecosystem/spark-doris-connector) 
+to compile it first. Then run `mvn package install -P shade` to build and install the extension.
+
+## Deploy
+Please copy jar file into `${BYZER_HOME}/plugin` .
