2) SQL file

• user_sql.sql

SELECT
    id,
    user_name userName,
    user_phone userPhone,
    create_time createTime,
    update_time updateTime
FROM c_user
WHERE update_time > : sql_last_value

• log_sql.sql

SELECT
    id,
    param_value paramValue,
    request_ip requestIp,
    create_time createTime,
    update_time updateTime
FROM c_log
WHERE update_time > : sql_last_value

3) Description of configuration parameters

• input parameter

statement_filepath: Read the location of the SQL statement
 schedule: Here the configuration executes every minute
 type: type, the identifier written to ES
 lowercase_column_names: Are fields lowercase?
record_last_run: Record the last execution time
 use_column_value: Use column values
 tracking_column: Distinguish incremental data based on the updateTime field written to ES
 tracking_column_type: The distinguished field type

• output parameter

hosts: ES service address
 Index: Index name, understand database name by analogy
 document_type: Type name, analogy understanding table name
