Overview
The OpenX SerDe. Used by Firehose for deserializing data, which means converting it from the JSON format in preparation for serializing it to the Parquet or ORC format. This is one of two deserializers you can choose, depending on which one offers the functionality you need. The other option is the native Hive / HCatalog JsonSerDe.

#column_to_json_key_mappings ⇒ Hash<String,String>
Maps column names to JSON keys that aren't identical to the column
names. This is useful when the JSON contains keys that are Hive
keywords. For example, timestamp
is a Hive keyword. If you have a
JSON key named timestamp
, set this parameter to {"ts":
"timestamp"}
to map this key to a column named ts
.

#convert_dots_in_json_keys_to_underscores ⇒ Boolean
When set to true
, specifies that the names of the keys include
dots and that you want Firehose to replace them with underscores.
This is useful because Apache Hive does not allow dots in column
names. For example, if the JSON contains a key whose name is
"a.b", you can define the column name to be "a_b" when using
this option.
The default is false
.
