> Currently writing t/h Spark DataSource connector, does not respect "
> "hoodie.parquet.max.file.size" setting: in the snippet pasted below i'm
> trying to limit the file-size to 16Mb, while on disk i'm getting ~80Mb files.
>
> The reason for that seem to be that we rely on ParquetWriter to control the
> file size (`canWrite` method), that relies in turn on FileSystem to trace how
> much was actually written to FS.
>
> The problem with this approach is that Spark is writing {*}lazily{*}:
> It creates instances of ParquetWriter which in turn cache the whole record
> group when `write` methods are invoked and only flushes the data to FS only
> _when closing_ the Writer (ie when `close`) is invoked
