Guanpx opened a new issue #5132:
URL: https://github.com/apache/hudi/issues/5132
**Describe the problem you faced**
OOM occurred when use bulk_insert cow table with flink BUCKET index
**To Reproduce**
Steps to reproduce the behavior:
1. use bulk_insert cow table with flink BUCKET index, that data size about
200w (flink batch mode)
**Expected behavior**
data source from hive, sink to hudi with flink
**Environment Description**
* Hudi version : master 0.11.0
* Flink version : 1.14.3
* Hadoop version : 3.0.0
* Storage (HDFS/S3/GCS..) : HDFS
* Running on Docker? (yes/no) : no
**Additional context**
hudi config
```
'path' = 'hdfs://nameservice-ha/hudi/dw/rds.db/hudi_fms_repay_plan',
'hoodie.parquet.compression.codec'= 'snappy',
'index.type' = 'BUCKET',
'table.type' = 'COPY_ON_WRITE',
'write.operation' = 'bulk_insert',
'write.tasks' = '3',
'hoodie.bucket.index.num.buckets' = '6',
'write.sort.memory' = '256',
'write.bulk_insert.shuffle_by_partition' = 'false',
'hoodie.bucket.index.hash.field' = 'id'
```
