…s first written ### Change Logs Although hudi has the function of dynamically estimating the size of the record, but it can only take effect if certain conditions are met, when the user commits for the first time, the default is to use [hoodie.copyonwrite.record.size.estimate = 1024], if the amount of data for the first commit is very large, and the user [hoodie.copyonwrite.record.size.estimate] parameter setting is not reasonable, it will lead to a lot of small files. ### Impact This pr avoids producing a lot of small files under certain circumstances ### Risk level (write none, low medium or high below) medium It has been verified in our production environment, you can refer to the test report in the issue https://issues.apache.org/jira/browse/HUDI-5315 ### Documentation Update _Describe any necessary documentation update if there is any new feature, config, or user-facing change_ - _The config description must be updated if new configs are added or the default value of the configs are changed_ - _Any new feature or user-facing change requires updating the Hudi website.
