> Nowadays, record level index is mainly implemented for `tagLocation`, and queries do not benefit from this, see [https://github.com/apache/hudi/pull/3508] for more detail. In this issue, we will implement record level index based on Apache Lucene to gain the following abilities:
> 1. For point query, we can get file level row number from record level index, combining parquet column index brought by Spark 3.2 to achieve accurate reading;
> 2. For `tagLocation`, we can directly get record location info from record level index.
