chitralverma opened a new issue, #38730: URL: https://github.com/apache/arrow/issues/38730
### Describe the enhancement requested Some important changes are suggested in the list below to improve the developer experience with the Dataset API of java/arrow. Most of these suggestions if implemented will lead to consistency with the [pyarrow dataset API](https://arrow.apache.org/docs/python/generated/pyarrow.dataset.dataset.html#pyarrow.dataset.dataset). 1. Support for providing Filesystem options like access_key etc. programmatically 2. Support for globbed paths and directories 3. Excluding invalid files 4. Additional documentation for already implemented functionality 1. Reading and writing to remote/ cloud stores (HDFS, S3, GCS ...) 2. Clarification of behaviour when reading multiple files. Why 2 or more files supplied, they may have different schema. Currently, only the schema of the last files is shown by `.inspect()` and this is not documented anywhere. This behaviour is the same in pyarrow. Maybe it's a good idea to allow users to provide a strategy like Error, Merge, LastFile etc. 3. Reading and writing partitioned datasets 4. Difference between `FileSystemDatasetFactory.inspect()` and `FileSystemDatasetFactory.finish().newScan(...).schema()`. Which one to use in which case? ### Component(s) Java -- This is an automated message from the Apache Git Service.
