DSS 5.1 Release notes¶

Migration notes ¶

Migration paths to DSS 5.1 ¶

From DSS 5.0: Automatic migration is supported, with the restrictions and warnings described in Limitations and warnings

From DSS 4.3: In addition to the restrictions and warnings described in Limitations and warnings, you need to pay attention to the restrictions and warnings applying to your previous versions. See 4.2 -> 4.3 and 4.3 -> 5.0

From DSS 4.2: In addition to the restrictions and warnings described in Limitations and warnings, you need to pay attention to the restrictions and warnings applying to your previous versions. See 4.2 -> 4.3 and 4.3 -> 5.0

From DSS 4.1: In addition to the restrictions and warnings described in Limitations and warnings, you need to pay attention to the restrictions and warnings applying to your previous versions. See 4.1 -> 4.2 and 4.2 -> 4.3 and 4.3 -> 5.0

From DSS 4.0: In addition to the restrictions and warnings described in Limitations and warnings, you need to pay attention to the restrictions and warnings applying to your previous versions. See 4.0 -> 4.1, 4.1 -> 4.2 and 4.2 -> 4.3 and 4.3 -> 5.0

Migration from DSS 3.1 and below is not supported. You must first upgrade to 5.0. See DSS 5.0 Release notes

How to upgrade ¶

It is strongly recommended that you perform a full backup of your DSS data directory prior to starting the upgrade procedure.

For automatic upgrade information, see Upgrading a DSS instance.

Pay attention to the warnings described in Limitations and warnings.

Limitations and warnings ¶

Automatic migration from previous versions (see above) is supported, but there are a few points that need manual attention.

Upgrade of Python packages ¶

The following Python packages have been upgraded in the builtin environment:

pandas (0.20 -> 0.23)
numpy (1.13 -> 1.15)
scikit-learn (0.19 -> 0.20)
xgboost (0.72 -> 0.80)

The pandas dependency is also upgraded in code environments.

Importantly, the dataiku Python package is not compatible with pandas 0.20 anymore. You must upgrade to pandas 0.23.

Rebuild of code environments ¶

Due to the upgraded dependency on pandas, it is necessary to update all previous Python code environments.

In most cases, you simply need, for each code environment, to go to the code environment page and click on the “Update” button (since the pandas 0.23 requirement is part of the base packages).

Retraining of machine-learning models ¶

XGBoost models trained with prior versions of DSS must be retrained when upgrading to 5.1. This includes models deployed to the flow (re-run the training recipe), models in analysis (retrain them before deploying) and API package models (retrain the flow saved model and build a new package)
“Isolation forests” models trained with prior versions of DSS and using “In-memory” engine must be retrained when upgrading to 5.1. This includes models deployed to the flow (re-run the training recipe), models in analysis (retrain them before deploying) and API package models (retrain the flow saved model and build a new package)

Multi-user-security configuration file move ¶

For improved security, the security module configuration file for Multi-User-Security has been moved from DATADIR/security/security-config.ini to /etc/dataiku-security/INSTALL_ID/security-config.ini.

DSS will automatically move the file upon upgrade, so you don’t need to perform any operation. However, any further update must be done on the /etc/dataiku-security/INSTALL_ID/security-config.ini. For more information, and details about INSTALL_ID, see the MUS setup documentation.

Dashboard exports ¶

Like with any upgrade, the Dashboards export feature must be reinstalled after upgrade. For more details, on how to reinstall this feature please see Setting up DSS item exports to PDF or images

Support removal notice ¶

DSS 5.1 removes support for Python 3.4. This constraint is caused by external libraries (notably pandas) that have removed the support for Python 3.4. Python 3.4 is also out of support upstream.

It is not possible to switch the version of Python used by code environments. If you have code environments using Python 3.4, you’ll need to (for each Python 3.4 code env):

Install Python 3.6
Delete the Python 3.4 code env
Create a Python 3.6 code env with the same name and same packages

Deprecation notice ¶

DSS 5.1 deprecates support for some features and versions. Support for these will be removed in a later release.

The prepare recipe running on the Hadoop Mapreduce engine is deprecated. We strongly advise you to use the Spark engine instead.

Version 5.1.0 - January 29th, 2019 ¶

DSS 5.1.0 is a very major upgrade to DSS with major new features.

New features ¶

Git integration for plugins editor ¶

The plugin editor now features full Git integration, allowing you to view the history of a plugin, revert changes, and to push and pull changes from a remote Git repository.

For more details, please see our tutorial and reference.

Import code libraries from Git ¶

In the library editor of each project, you can now import code from external Git repositories. For example, if you have code that has been developed outside of DSS and is available in a Git repository (for example, a library created by another team), you can import this repository (or a part of it) in the project libraries, and use it in any code capability of DSS (recipes, notebooks, web apps, …).

This code can then be updated from the external Git repository, either manually or automatically.

For more details, please see our tutorial and reference.

More code reuse capabilities ¶

Combined with the ability to import code libraries from Git, new features for code reuse have been added:

R code can now use per-project libraries, just like Python code.
For both Python and R code, you can now have multiple libraries folders per project
For both Python and R code, you can now use the libraries of one project in another project

For more details, please see reusing Python code and reusing R code

Prepare recipe in-database (SQL)¶

A subset of preparation processors can now be translated to SQL queries. When a prepare recipe contains translatable processors, it can be executed fully in-database, which can provide speed-ups up to hundreds of times.

For more details, please see Execution engines.

Lightning-fast prepare recipe on Spark ¶

DSS now includes a new engine for data preparation on Spark that can provide significant performance boosts.

A subset of preparation processors are compatible with the optimized Spark engine, which will be used automatically whenever possible. When non-compatible processors are present, DSS automatically falls back to the previous engine.

For more details, please see Execution engines.

Containerized execution of notebooks ¶

Notebooks (Python and R) can now be run in Docker and Kubernetes

For more details, please see Containerized notebooks.

Databricks ¶

DSS now features an experimental and limited integration with Databricks to leverage Databricks as a Spark execution engine. Please contact your Dataiku Account Executive for more details.

Web apps as plugins ¶

Web apps can now be turned into plugins. This allows you to have reusable and instantiable web apps.

Some use cases notably include making custom visualizations for datasets.

For more details, please see our tutorial and reference.

Use Dataiku libs and develop code outside of DSS ¶

You can now use the Dataiku Python and R libraries outside of DSS in order to develop code for DSS (recipes, webapps, …) outside of DSS and in your favorite IDE.

For more details, please see using Python API outside of DSS and using R API outside of DSS

Folding the Flow view ¶

You can now hide parts of the Flow in order to improve the readability of very large flows. You can easily hide all parts of a flow upstream/downstream of a single node.

External hosting of runtime databases ¶

DSS maintains a number of databases, called the “runtime databases” that store some additional information, which is mostly “non-primary” information (i.e. which can be rebuilt), like history of jobs, metrics, state of datasets, timelines, discussions, …

By default, the runtime databases are hosted internally by DSS, using an embedded database engine (called H2). You can also move the runtime databases to an external PostgreSQL server. Moving the runtime databases to an external PostgreSQL server improves resilience, scalability and backup capabilities.

For more details, please see The runtime databases.

Exporting the Flow as an image ¶

You can now export the Flow of a project as an image or a PDF.

For more details, please see Exporting the Flow to PDF or images.

Probability calibration ¶

When training a classification model, you can now choose to apply a calibration of the predicted probabilities.

The purpose of calibrating probabilities is to bring the actual frequency of classes occurrence as close as possible to the predicted probability of such occurrence.

For more details, please see Prediction settings.

Models export as PMML and POJO ¶

You can now export a trained model as a PMML file for scoring with any PMML-compatible scorer.

You can also export trained models as a set of Java classes for extremely efficient scoring in any JVM application.

For more details, please see Exporting models.

Duplicate projects ¶

You can now easily duplicate a DSS project, optionally duplicating the content of some datasets.

RStudio integration ¶

In addition to the ability to use the DSS R API outside of DSS, DSS now features several integration points with RStudio:

Ability to develop code for DSS (recipes, …) directly in RStudio
RStudio Desktop/Server addins for easy connection to DSS and download/upload of recipes
Embedding of the RStudio Server UI in DSS
Easy configuration of RStudio Server for connection with DSS

For more details, please see our tutorial and reference.

Other notable enhancements ¶

Copy-paste preparation steps ¶

You can now copy and paste preparation steps, either within a single preparation recipe or across preparation recipes, or even across DSS instances.

Copy-paste scenario steps ¶

You can now copy and paste scenario steps, either within a single scenario or across scenarios, or even across DSS instances.

Support for CDH 6 ¶

DSS now supports CDH 6.0 and 6.1

For more details, please see Cloudera CDH

New capabilities for Snowflake ¶

DSS now supports a fast-path to sync from S3 to Snowflake.

For more details, please see Snowflake.

Setting distribution / primary index on Teradata, Redshift and Greenplum ¶

Additional options are now available for these databases:

Ability to control the primary index for Teradata datasets
Ability to control the distribution keys for Greenplum datasets
Ability to control the distribution and sort keys for Redshift datasets

Support for impersonation on Teradata ¶

You can now use the “proxyuser” mechanism of Teradata to impersonate end-users for all database access.

For more details, please see Teradata

Support for custom query banding on Teradata ¶

In order to provide for better audit, it can be interesting to add in the Query band of your Teradata queries information about the queries that are being performed.

DSS now lets you easily do that and track which users and jobs, … perform Teradata queries.

For more details, please see Teradata.

The join recipe now supports < and > operators (in addition to <= and >=)

Datasets ¶

A potential memory overrun when listing too many partitions has been fixed
GCS: Fixed issue with datasets whose size was a multiple of 4MB
“Cell value” metric now works properly even in the presence of other metrics
Reduced the number of “getBucketLocation” AWS API calls

Code ¶

It is now possible to use datasets in a Python or R recipe, even if they are not declared as inputs or outputs. For example:

dataset = dataiku.Dataset("mydataset_that_is_not_in_input", ignore_flow=True)
df = dataset.get_dataframe()

Various bugs on SQL code formatter have been fixed

Data preparation ¶

CJK characters can now be used as literals in the Python processor

Dashboards ¶

It is now possible to export dashboards on a machine without outgoing Internet connection (after initial setup)

Machine learning ¶

Don’t try to use Optimized scoring when a custom text preprocessing is in effect
It is now possible to tune the scoring batch size when using the Local (Python) engine for scoring

Misc ¶

Clear job logs macro now removes the job folders instead of just emptying them
