yugu created PARQUET-1056:
-----------------------------
Summary: Partial Reading when process crash
Key: PARQUET-1056
URL: https://issues.apache.org/jira/browse/PARQUET-1056
Project: Parquet
Issue Type: Wish
Components: parquet-cpp
Affects Versions: cpp-1.1.0
Reporter: yugu
questions are actually twofold:
1. is there a way to write data column by column ?
I see a columnwriter but seems that's for arrow..
2. was wondering if there is a way to preserve the footer information once in a
while, in case the process crashes. for now if the proc crash the parquet file
become unreadable...
In the code the close function (for parquetfilewriter) basically just flushes
and close the stream. maybe a separate api for flush footer to target file?
(or maybe there is an existing way for making things robust I missed)
thanks!
