@hejufang the issue should be fixed if you rebase your branch

@flinkbot run azure

[hejufang]

@JingGe Thank you for your advice. The issue is fixed.

[hejufang]

@pnowojski kindly remind.

[Zakelly]

Thanks for the PR! It looks good.

I would suggest a refine, such as "Monitor the count of reads avoided by full filter while the data actually exists in RocksDB".

[hejufang]

Thanks for your advice, I’ve refined this description.
