Added a JAR file on Flink SQL but can't create a Clickhouse sink table properly

[nsia-henry]

Hi,

I am trying to create a Clickhouse (CH) sink table using Flink SQL. I am new at using Flink SQL and I was trying to create a sink table to store data into CH. To do so,

1. I dowloaded a flink-clickhouse-sink-1.3.1.jar from https://jar-download.com/artifacts/ru.ivi.opensource/flink-clickhouse-sink/1.3.1

2. Included it in the CLI;
   

3. I created a target table in CH

CREATE TABLE default.flink_table (    
  CUSTOMERID String,
  CAMPAIGNID String,
  TOTALRECIPIENTS Int32, 
  DELIVERYRATE Int32,
  STATUS String
) 
Engine = MergeTree()
ORDER BY tuple;
 

4. I created a sink table from flink like so;

CREATE TABLE flink_table_sink (
    CUSTOMERID STRING, 
    CAMPAIGNID STRING,
    TOTALRECIPIENTS INT,
    DELIVERYRATE Int32,
    STATUS String,
    PRIMARY KEY (CAMPAIGNID) NOT ENFORCED
) 
WITH (
    'connector' = 'clickhouse',
    'url' = 'clickhouse://ip:port',
    'database-name' = 'default',
    'table-name' = 'flink_table'
);

5. I tried to insert values into the sink table (flink_table_sink), I got this error message;
   
   To me it looks like Flink didn't recognize the clickhouse flink jar file, but I can't figure out why. Because it still shows it in the jar files.

Can anyone help?

This is a "High-performance library for loading data to ClickHouse". There is no stable high level table api yet before flink version 1.13. So you may take a look at the readme page, and use it in a streaming API way by programming.
