TDengine Writer ​

TDengine Writer plugin implements writing data to TDengine database system. In the underlying implementation, TDengine Writer connects to remote TDengine database through JDBC JNI driver and executes corresponding SQL statements to batch write data to TDengine database.

Prerequisites ​

Considering performance issues, this plugin uses TDengine's JDBC-JNI driver, which directly calls the client API (libtaos.so or taos.dll) to send write and query requests to taosd instances. Therefore, dynamic library link files need to be configured before use.

First copy plugin/writer/tdenginewriter/libs/libtaos.so.2.0.16.0 to /usr/lib64 directory, then execute the following commands to create soft links:

bash
ln -sf /usr/lib64/libtaos.so.2.0.16.0 /usr/lib64/libtaos.so.1
ln -sf /usr/lib64/libtaos.so.1 /usr/lib64/libtaos.so

Example ​

Assume the table to be written is as follows:

sql
create table test.addax_test (
    ts timestamp,
    name nchar(100),
    file_size int,
    file_date timestamp,
    flag_open bool,
    memo nchar(100)
);

This plugin is based on RDBMS Writer, so you can refer to all configuration items of RDBMS Writer.
