> We have a basic implementation of inline filesystem, to read a file format
> like Parquet, embedded "inline" into another file.
> [https://github.com/apache/hudi/blob/master/hudi-common/src/test/java/org/apache/hudi/common/fs/inline/TestInLineFileSystem.java]
> for sample usage.
> This idea here is to see if we can embed parquet/hfile formats into the Hudi
> log files, to get columnar reads on the delta log files as well. This helps
> us speed up query performance, given the log is row based today. Once Inline
> FS is available, enable parquet logging support with HoodieLogFile. LogFile
> can expose a writer (essentially ParquetWriter) and users can write records
> as though writing to parquet files. Similarly on the read path, a reader
> (parquetReader) will be exposed which the user can use to read data out of
> it.
> This Jira tracks work to implement such parquet inlining into the log format
> and have the writer and reader use it.
