---------------------------------
Summary: Add get off heap buffer in memory segment
Key: FLINK-32213
URL: https://issues.apache.org/jira/browse/FLINK-32213
Project: Flink
Issue Type: Improvement
Components: Runtime / Task
Affects Versions: 1.18.0
Reporter: Fang Yong
When flink job writes data to data lake such as paimon, iceberg and hudi, the
sink will write data to writer buffer first, then flush the data to file
system. To manage the writer buffer better, we'd like to allocate segment from
managed memory in flink and get off heap buffer to create writer buffer
