gubinjie opened a new issue, #6914:
URL: https://github.com/apache/hudi/issues/6914
Hudi:0.10.1
Here is my script for a hudi table created via Flink:
`create table paat_hudi_flink_tyc_company
(
company_id string,
company_name string,
update_time timestamp(3) comment 'Last update time',
primary key (company_id) not enforced
) with (
'connector' = 'hudi',
'path' = 'hdfs://******/user/hudi/warehouse/paat_ods_hudi.db/',
'hoodie.datasource.write.recordkey.field' = 'company_id',
'write.precombine.field' = 'update_time', 'write.tasks' = '1',
'compaction.tasks' = '1', 'write.rate.limit' = '2000', 'table.type' =
'MERGE_ON_READ',
'compaction.async.enable' = 'true', 'compaction.trigger.strategy' =
'num_or_time',
'compaction.max_memory' = '1024', 'changelog.enable' = 'true',
'read.streaming.enable' = 'true',
'read.streaming.check-interval' = '30', 'hive_sync.enable' = 'true',
'hive_sync.mode' = 'hms',
'hive_sync.metastore.uris' = 'thrift://******:9083',
'hive_sync.jdbc_url' = 'jdbc:hive2://******:10000',
'hive_sync.table' = '******', 'hive_sync.db' = '******',
'hive_sync.username' = '******',
'hive_sync.password' = '******', 'hive_sync.support_timestamp' = 'true'
);`
hoodie.datasource.write.recordkey.field is company_id.
write.precombine.field is update_time
When the same data (_hoodie_commit_time is different, update_time is the
same) is inserted into Hudi in different time periods, duplicate data will
appear.
may I ask if this is normal?
The following is the specific data:
_hoodie_commit_time|_hoodie_commit_seqno
|_hoodie_record_key|_hoodie_partition_path|_hoodie_file_name
|company_id |company_name |update_time |
-------------------|---------------------------|------------------|----------------------|--------------------------------------------------------------------|-----------|--------------------|-------------|
