Configuration settings that are used during decoding or reading Parquet files
Configuration settings that are used during decoding or reading Parquet files
timeZone
set it to TimeZone which was used to encode time-based data that you want to read; machine's time zone is used by default
hadoopConf
use it to programmatically override Hadoop's Configuration

def read[T](path: String, options: Options = Options(), filter: Filter = Filter.noopFilter)(implicit reader: ParquetReader[T]): ParquetIterable[T]

Creates new ParquetIterable over data from given path.
Creates new ParquetIterable over data from given path.
Path can represent local file or directory, HDFS, AWS S3, Google Storage, Azure, etc. Please refer to Hadoop client documentation or your data provider in order to know how to configure the connection.
T
type of data that represents the schema of the Parquet file, e.g.:
```
case class MyData(id: Long, name: String, created: java.sql.Timestamp)
```
path
URI to Parquet files, e.g.:
```
"file:///data/users"
```
options
configuration of how Parquet files should be read
filter
optional before-read filtering; no filtering is applied by default; check Filter for more details
Note
Remember to call close() on iterable in order to free resources!
implicit def reader[T](implicit arg0: ParquetRecordDecoder[T]): ParquetReader[T]
