-------------------------------
Summary: Support to only read changelogs of specific database and
table for canal-json format
Key: FLINK-19002
URL: https://issues.apache.org/jira/browse/FLINK-19002
Project: Flink
Issue Type: New Feature
Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
Reporter: Jark Wu
Fix For: 1.12.0
Usually, users use Canal to synchronize binlog data from various MySQL
databases and tables into a single Kafka topic. However, currently, canal-json
can't support this case, because it requires the canal data in the topic should
be in the same data format.
This issue propose to introduce a new option "canal-json.database" and
"canal-json.table" to filter out the specific data. It would be great to
support table list or table pattern in case of all the tables have the same
schema.
