memory:
* Writer's memory buffer, shared and preempted by all writers of a single
task. This memory value can be adjusted by the `write-buffer-size` table
property.
* Memory consumed when merging several sorted runs for compaction. Can be
adjusted by the `num-sorted-run.compaction-trigger` option to change the number
of sorted runs to be merged.
* If the row is very large, reading too many lines of data at once will
consume a lot of memory when making a compaction. Reducing the
`read.batch-size` option can alleviate the impact of this case.
-* The memory consumed by writing columnar (ORC, Parquet, etc.) file.
Decreasing the `orc.write.batch-size` option can reduce the consumption of
memory for ORC format.

* If files are automatically compaction in the write task, dictionaries for
certain large columns can significantly consume memory during compaction.
* To disable dictionary encoding for all fields in Parquet format, set
`'parquet.enable.dictionary'= 'false'`.
* To disable dictionary encoding for all fields in ORC format, set
`orc.dictionary.key.threshold='0'`. Additionally,set
`orc.column.encoding.direct='field1,field2'` to disable dictionary encoding for
specific columns.
