# 介绍 *[Chunjun 1.12 新特性](docs/changeLog.md)* Chunjun是一个基于Flink的批流统一的数据同步工具，既可以采集静态的数据，比如MySQL，HDFS等，也可以采集实时变化的数据，比如MySQL binlog，Kafka等。**同时，Chunjun也是支持原生FlinkSql所有语法和特性的计算框架**，**并且提供了大量[案例](Chunjun-examples)**。Chunjun目前包含下面这些特性： - 大部分插件支持并发读写数据，可以大幅度提高读写速度； - 部分插件支持失败恢复的功能，可以从失败的位置恢复任务，节约运行时间；[失败恢复](docs/restore.md) - 关系数据库的Source插件支持间隔轮询功能，可以持续不断的采集变化的数据；[间隔轮询](docs/offline/reader/mysqlreader.md) - 部分数据库支持开启Kerberos安全认证；[Kerberos](docs/kerberos.md) - 可以限制source的读取速度，降低对业务数据库的影响； - 可以记录sink插件写数据时产生的脏数据； - 可以限制脏数据的最大数量； - 支持多种运行模式； - **同步任务支持执行flinksql语法的transformer操作；** - **sql任务支持和flinkSql自带connectors[共用](docs/conectorShare.md)；** Chunjun目前支持下面这些数据库： | | Database Type | Source | Sink | Lookup |:----------------------:|:--------------:|:---------------------------------------------------------:|:---------------------------------------------------------:|:---------------------------------------------------------:| | Batch Synchronization | MySQL | [doc](docs/connectors/mysql/mysql-source.md) | [doc](docs/connectors/mysql/mysql-sink.md) |[doc](docs/connectors/mysql/mysql-lookup.md) | | | TiDB | | 参考mysql |参考mysql | | | Oracle | [doc](docs/connectors/oracle/oracle-source.md) | [doc](docs/connectors/oracle/oracle-sink.md) |[doc](docs/connectors/oracle/oracle-lookup.md) | | | SqlServer | [doc](docs/connectors/sqlserver/sqlserver-source.md) | [doc](docs/connectors/sqlserver/sqlserver-sink.md) |[doc](docs/connectors/sqlserver/sqlserver-lookup.md) | | | PostgreSQL | [doc](docs/connectors/postgres/postgres-source.md) | [doc](docs/connectors/postgres/postgres-sink.md) |[doc](docs/connectors/postgres/postgres-lookup.md) | | | DB2 | [doc](docs/connectors/db2/db2-source.md) | [doc](docs/connectors/db2/db2-sink.md) |[doc](docs/connectors/db2/db2-lookup.md) | | | ClickHouse | [doc](docs/connectors/clickhouse/clickhouse-source.md) | [doc](docs/connectors/clickhouse/clickhouse-sink.md) |[doc](docs/connectors/clickhouse/clickhouse-lookup.md) | | | Greenplum | [doc](docs/connectors/greenplum/greenplum-source.md) | [doc](docs/connectors/greenplum/greenplum-sink.md) | | | | KingBase | [doc](docs/connectors/kingbase/kingbase-source.md) | [doc](docs/connectors/kingbase/kingbase-sink.md) | | | | MongoDB | [doc](docs/connectors/mongodb/mongodb-source.md) | [doc](docs/connectors/mongodb/mongodb-sink.md) |[doc](docs/connectors/mongodb/mongodb-lookup.md) | | | SAP HANA | [doc](docs/connectors/saphana/saphana-source.md) | [doc](docs/connectors/saphana/saphana-sink.md) | | | | ElasticSearch7 | [doc](docs/connectors/elasticsearch7/es7-source.md) | [doc](docs/connectors/elasticsearch7/es7-lookup.md) |[doc](docs/connectors/elasticsearch7/es7-sink.md) | | | FTP | [doc](docs/connectors/ftp/ftp-source.md) | [doc](docs/connectors/ftp/ftp-sink.md) | | | | HDFS | [doc](docs/connectors/hdfs/hdfs-source.md) | [doc](docs/connectors/hdfs/hdfs-sink.md) | | | | Stream | [doc](docs/connectors/stream/stream-source.md) | [doc](docs/connectors/stream/stream-sink.md) | | | | Redis | | [doc](docs/connectors/redis/redis-sink.md) |[doc](docs/connectors/redis/redis-lookup.md) | | | Hive | | [doc](docs/connectors/hive/hive-sink.md) | | | | Hbase | [doc](docs/connectors/hbase/hbase-source.md) | [doc](docs/connectors/hbase/hbase-sink.md) |[doc](docs/connectors/hbase/hbase-lookup.md) | | | Solr | [doc](docs/connectors/solr/solr-source.md) | [doc](docs/connectors/solr/solr-sink.md) | | | | File | [doc](docs/connectors/file/file-source.md) | | | | | StarRocks | | [doc](docs/connectors/starrocks/starrocks-sink.md) | | | Stream Synchronization | Kafka | [doc](docs/connectors/kafka/kafka-source.md) | [doc](docs/connectors/kafka/kafka-sink.md) | | | | EMQX | [doc](docs/connectors/emqx/emqx-source.md) | [doc](docs/connectors/emqx/emqx-sink.md) | | | | MySQL Binlog | [doc](docs/connectors/binlog/binlog-source.md) | | | | | Oracle LogMiner | [doc](docs/connectors/logminer/LogMiner-source.md) | | | | | Sqlserver CDC | [doc](docs/connectors/sqlservercdc/SqlserverCDC-source.md) | | | # 快速开始 请点击[快速开始](docs/quickstart.md) # 通用配置 请点击[插件通用配置](docs/generalconfig.md) # 统计指标 请点击[统计指标](docs/statistics.md) # Iceberg 请点击 [Iceberg](docs/iceberg.md) # Kerberos 请点击[Kerberos](docs/kerberos.md) # Questions 请点击[Questions](docs/questions.md) # 如何贡献Chunjun 请点击[如何贡献Chunjun](docs/contribution.md) # License Chunjun is under the Apache 2.0 license.
