Jiaming Yuan 41c6813496 Preserve order of saved updaters config. (#9355) 
- Save the updater sequence as an array instead of object.
- Warn only once.

The compatibility is kept, but we should be able to break it as the config is not loaded
in pickle model and it's declared to be not stable.

Jiaming Yuan f4798718c7 Use hist as the default tree method. (#9320) 2023-06-27 23:04:24 +08:00
Jiaming Yuan 1f9a57d17b [Breaking] Require format to be specified in input URI. (#9077) 
Previously, we use `libsvm` as default when format is not specified. However, the dmlc
data parser is not particularly robust against errors, and the most common type of error
is undefined format.

Along with which, we will recommend users to use other data loader instead. We will
continue the maintenance of the parsers as it's currently used for many internal tests
including federated learning.

Jiaming Yuan c1786849e3 Use array interface for CSC matrix. (#8672) 
* Use array interface for CSC matrix.

Use array interface for CSC matrix and align the interface with CSR and dense.

- Fix nthread issue in the R package DMatrix.
- Unify the behavior of handling `missing` with other inputs.
- Unify the behavior of handling `missing` around R, Python, Java, and Scala DMatrix.
- Expose `num_non_missing` to the JVM interface.
- Deprecate old CSR and CSC constructors.
