* Add flattenSpec support to the Avro parser.
Also:
- Refactor the JSONPathParser a bit so it can share flattening code
with Avro (see ObjectFlatteners).
- Remove the JSONParser. It was only used in two places: by
UriNamespaceExtractor, and as a base for JSONToLowerParser. Migrated
the former to JSONPathParser and made the latter a standalone.
- Move GenericRecordAsMap to the Parquet extension, since the Avro
extension no longer uses it.
* Fix indentation.
* Fix equals/hashCode.
* Add Date support to the parquet reader
Add support for the Date logical type. Currently this is not supported. Since the parquet
date is number of days since epoch gets interpreted as seconds since epoch, it will fails
on indexing the data because it will not map to the appriopriate bucket.
* Cleaned up code and tests
Got rid of unused json files in the examples, cleaned up the tests by
using try-with-resources. Now get the filenames from the json file
instead of hard coding them and integrated general improvements from
the feedback provided by leventov.
* Got rid of the caching
Remove the caching of the logical type of the time dimension column
and cleaned up the code a bit.
Hi guys,
Since Spark 2.x uses Parquet 1.8.2, we would like to update Druid's parquet library from 1.8.1 to 1.8.2 as well. It includes a lot of patches, performance improvements and better compatibility:
