HunterXHunter updated HUDI-4726:
--------------------------------
Description:
{code:java}
-- create
CREATE TABLE hudi_4726(
id string,
msg string,
`partition` STRING,
PRIMARY KEY(id) NOT ENFORCED
)PARTITIONED BY (`partition`)
WITH (
'connector' = 'hudi',
'write.operation'='upsert',
'path' = 'hudi_4726',
'index.type' = 'BUCKET',
'hoodie.bucket.index.num.buckets' = '2',
'compaction.delta_commits' = '2',
'table.type' = 'MERGE_ON_READ',
'compaction.async.enabled'='true')
-- insert
INSERT INTO hudi_4726 values ('id1','t1','par1')
INSERT INTO hudi_4726 values ('id1','t2','par1')
INSERT INTO hudi_4726 values ('id1','t3','par1')
INSERT INTO hudi_4726 values ('id1','t4','par1')
-- .hoodie
t1.deltacommit (t1)
t2.deltacommit (t2)
t3.commit (t2)
t4.deltacommit (t3)
t5.deltacommit (t4)
t6.commit (t4)
t3.parquet
t6.parquet
-- read
exp1 : 'read.start-commit'='t1', 'read.end-commit'='t1' -- (true,+I[id1, t1,
par1])
exp2 : 'read.start-commit'='t1', 'read.end-commit'='t2' -- (true,+I[id1, t2,
par1])
exp3 : 'read.start-commit'='t1', 'read.end-commit'='t3' -- (true,+I[id1, t2,
par1])
-- but
'read.start-commit'='0', 'read.end-commit'='t3' -- (nothing) -- expect should
be like exp3.
--
The root of the problem is `IncrementalInputSplits.inputSplits`, because
`startCommit` is out of range, `fullTableScan` is `true`, finally, the file
read is t6..parquet instead of t3.parquet.{code}
> When using Flink for incremental query, when `read.start-commit is out of
> range`, full table scanning should not be performed.
