current stable version

3.2.3

Note: As of 3.2.1, the package class names have been changed and are therefore no longer compatible with 3.1.x versions.

The project, originally from Ali's DataX, has been streamlined and adapted, as described below

Description of functional differences

Removed

Deleted databases that were restricted to Ali internal databases that were not available in non-Ali groups and were therefore deleted outright, including:

ADS
DRDS
OCS
ODPS
OSS
OTS

Added

Added some plug-ins, which currently include

reader plugin

clickhousereader
dbffilereader
hbase20xreader
jsonfilereader
kudureader
influxdbreader
httpreader
elastichsearchreader
tdenginereader

writer plugin

dbffilewrite
greenplumwriter
kuduwriter
influxdbwriter
tdenginewriter

Some plug-in enhancements are listed below

rdbms-ralative plugins

add support for almost basic data type, and some complex data type.

hdfswriter

Add support for Decimal data type.
Add support for writing Parquet files.
Add support for writing with the overwrite mode.
Add support for more compression algorithm.
The temporary directory location is changed to a hidden directory under the current write directory, which solves the problem of automatic partition increase caused by the previous parallelism with the write directory.
In overwrite mode, the file deletion mechanism has been improved to reduce the time window when the corresponding table query is empty

hdfsreader

Add support for reading Parquet files.
Add support for more compression algorithm.

hbasex11sqlwrite

Add support for Kerberos authentication.

oraclewriter

Add support for merge into statement.

postgresqlwriter

Add support for insert into ... on conflict statement.

rdbmsreader/rdbmswriter

Add support TDH Inceptor, Trino query engine

compile and package

git clone https://github.com/wgzhao/datax.git DataX
cd DataX
mvn clean package
mvn package assembly:single

If you want compile doc, you can execute the following instructions.

cd docs
mvn clean package

After successful compilation and packaging, a datax-<version> folder will be created in the target/datax directory of the project directory, where <version indicates the version.

begin your first job

The job subdirectory contains many sample jobs, of which job.json can be used as a smoke-out test and executed as follows

cd target/datax/datax-<version>
python bin/datax.py job/job.json

The output of the above command is roughly as follows.
