Lefty Leverenz commented on HIVE-16222:
---------------------------------------
Doc note: This adds *hive.vectorized.row.serde.inputformat.excludes* to
HiveConf.java and changes the default value of
*hive.vectorized.use.row.serde.deserialize* to true, so the wiki needs to be
updated.
* [Configuration Properties -- Vectorization |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-Vectorization]
** [hive.vectorized.use.row.serde.deserialize |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.vectorized.use.row.serde.deserialize]
Added a TODOC3.0 label.
(Welcome back, Sergey.)
> add a setting to disable row.serde for specific formats; enable for others

> Per [~gopalv]
> {quote}
> row.serde = true ... breaks Parquet (they expect to get the same object back,
> which means you can't buffer 1024 rows).
> {quote}
> We want to enable this and vector.serde for text vectorization. Need to turn
> it off for specific formats.
