Paimon中如何创建动态分桶？

# 设置bucket为-1（主键表）
'bucket' = '-1'
#设置每个桶的目标行数
'dynamic-bucket.target-row-num' = 2000000
#设置初始化时的桶数量
`dynamic-bucket.initial-buckets` = 1

CREATE TABLE if not EXISTS product2 (product_id BIGINT, price DOUBLE, sales BIGINT)
WITH
  (
    -- 'target-file-size' = '256 MB',
    -- 'file.format' = 'parquet',
    -- 'file.compression' = 'zstd',
    -- 'file.compression.zstd-level' = '3',
    -- 'write-only' = 'true',
    -- 'bucket' = '-1',
    -- 'dynamic-bucket.target-row-num' ='2000000',
    -- 'dynamic-bucket.initial-buckets' = '1'
  );
