Enterprise Data Lake (EDL)


Core Data Preparation


  • New Advanced Data Preparation functions: Users can utilizemore than 50 new advanced data preparation functions for Statistical, Text, Math, Date/Time manipulations. Window functions help with calculation on a data window such as Rolling Average, Rolling Sum, Lead/Lag, Fill, Sessionize etc. Cluster and Categorize function uses phonetic algorithms to cluster data and then help users easily standardize. Delete duplicate rows function helps removing exact duplicates from the data.
  • Apply Active Rules: Users can Apply external pre-built rules with Active Transformations to support DQ processing like Fuzzy Matching and Consolidation. Expert users can use Informatica Developer Tool to build complex rules including active transformation and then expose those to the data preparation users. This helps collaboration, standardization, extensibility and re-usability.
  • Data Preparation for Avro and Parquet files: Users can add Avro and Parquet files to a project in addition to Hive tables and other file formats such as delimited files and JSONL files. This eliminates the need for creating a Hive table on top of files. They can structure the hierarchical data in row-column form by extracting specific attributes from the hierarchy, and canexpanding (or exploding) arrays into rows in the worksheet.


Self-service and Collaboration

  • Functional and UX Improvements: Users can apply conditions during aggregation, reorder sheets as needed. Recipe panel clearly shows steps that failed during data and recipe refresh. The “Back-in-time” functionality is now more on-demand to improve user experience for Edit step, Copy/Paste step etc.
  • Improved CLAIRE based recommendations: Improved user productivity with additional CLAIRE based recommendations for alternate assets upstream and related by PK-FK. During join, users are prompted to review sampling criteria in case of low overlap of join keys. User also get new data prep suggestions based on data types that are handy shortcuts to frequently used functions.
  • Ability to add recipe comments: Users can add comments to various recipe steps, view comments by other users for better collaboration and auditing.
  • Save mappings for Recipes: Users have option to save mappings corresponding to recipes for a worksheet instead of executing full at-scale execution and creation of new output table. This way expert IT users can inspect the mapping and execute at the appropriate time and resource levels.


Enterprise Focus

  • Support for S3, ADLS/WASB and MapR-FS files: Users can prepare data files directly from various file systems such as AWS S3, Azure ADLS and WASB and also for MapR-FS in addition to HDFS.
  • Spark Execution: Spark is used as the default execution engine for better performance and it also allows data prep users apply executing rules built with mapplets using advanced transformations such as Python transforms .
  • Autoscaling on AWS EMR: Customers can start with minimal number of EMR nodes and then auto-scale based on rules for resource consumption to lower overall total cost of ownership for data lakes in AWS.
  • Integration with Informatica Dynamic Data Masking: Data protection and governance is improved using Informatica Dynamic Data Masking. Based on DDM policies, data will be masked at various touch points such as preview, prepare, publish and download etc.
  • Scalability improvements: Performance, scalability and longevity improvements have been made in various services to support enterprise scale deployments with large number of users.


Enterprise Data Catalog (EDC)


  • Collaboration: Data Analysts, Data Scientists and Line of Business users will now be able to find the most relevant, most trusted datasets for their analytic needs faster with Enterprise Data Catalog(EDC) v10.2.2. EDC 10.2.2 includes both top down and bottom up collaboration capabilities that bring to forefront the otherwise deeply siloed knowledge about trustworthiness and usefulness of datasets. This new capability will help data consumers save weeks, sometimes months of efforts in finding and using the right dataset.
    • Dataset Certifications: With EDC v10.2.2, Subject Matter Experts, Data Stewards and Data Owners will be able to certify datasets and data elements adding context information like data usage and constraints. Using EDC’s machine learning based semantic search, EDC will surface these certified datasets at the top of the search results to guide users to use these certified datasets among all other similarly named datasets in the organization.
    • Reviews and Ratings: Data consumers like Data Analysts and Data Scientists can now review and rate datasets. EDC pushes datasets that are rated highly to the top of the search results. There are new facets that are available to narrow down search results to highly rated datasets only.
    • Questions and Answers: Users will be able to use a new question/answer platform that allows subject matter experts to answer the most common questions of the data consumers. This will help data consumers to find experts, ask questions and see answers in the context of the dataset. For subject matter experts, this will mean less work and more reuse of information as they need not response to multiple emails and phone calls for the same queries on data.
  • Change Notifications: With change notifications, EDC will provide data consumers an easy way to stay on top of any metadata changes happening to their data assets. Users will be able to follow any datasets in the catalog and whenever scanners detect any changes to these datasets, both in-app and email notifications will be sent to the user. Additionally super users like database administrators, stewards and owners can follow entire databases and other metadata resources to get notified on any changes happening in the database.
  • Intelligent Business Glossary Associations: One of the most important and most tedious data governance tasks is to associate business glossary terms to physical data assets. In EDC v10.2.2 the glossary association process is a lot more easier. By using the CLAIRE based AI engine, the right business glossary terms are matched with the right physical assets at the data element level. This method uses the data domain discovery and data similarity capabilities to power automatic glossary associations with the goal of making the data stewards and business analysts responsible for this task about 2X more productive by providing these machine learning based assistants.
    • Business Glossary Assignment Report: EDC v10.2.2 includes a new business glossary assignment report at the resource level to help data stewards understand glossary association coverage for a resource in one place. Data Stewards will also be able to curate(accept/reject) all glossary recommendations from this new report as well.
  • Metadata and Profile Filters: Catalog and profile only selected metadata from databases, data warehouses and big data sources. Users will be able to provide both inclusion and exclusion criteria to filter datasets that are cataloged and profiled. The filter criteria can be a list of names or regular expressions that are matched against table/view names.
  • Remote Metadata Scanner: Catalog metadata from data sources that are behind a firewall or are remote with port restrictions. With EDC v10.2.2 a direct network connection from the Catalog to the data source is no longer required. Remote Metadata Scanner Utility can be downloaded and setup in a server close to the data source/in the same network and the extracted metadata can be uploaded to the catalog. Currently only metadata scan is supported for Oracle, SQL Server and Teradata.
  • New Scanners
    • Workday: Manage Workday metadata for governance, risk/compliance andself service analytics
    • Google BigQuery: Manage Google BigQuery metadata for governance, risk/compliance andself service analytics
  • Performance Improvements: EDC v10.2.2 includes a new graph schema that improves the performance of tasks like parameter assignment (63x faster), resource purge (5x faster) and re-index (2.5x faster). Additionally, there are all round scanner performance improvements in the areas of auto-connection assignments (340x faster), SAP Business Objects scanner (1.5x faster), Oracle scanner (2x faster) and IBM Cognos scanner (2x faster).

Informatica 10.2.2 Release Notes



Customers use Informatica Big Data Management (BDM) product to access metadata (using developer client tool) as well as data (through Data Integration Service) for Hadoop based sources (HDFS files, HBase, Hive, MapR-DB) as well as non-Hadoop sources. One of the major pain points with accessing Hadoop data sources is related to the non-trivial configuration effort that goes in configuring access to the Hadoop systems including the Kerberos configuration using kinit tool, keytab files etc. This document explains how Metadata Access Service simplifies the configuration effort and also enables more secure metadata access from Hadoop data sources.

Metadata access process without Metadata Access Service

The metadata access process before Metadata Access Service to import metadata from a Hadoop data source like HDFS files, HBase, Hive, MapR-DB included the following steps. Note that the below steps were needed to be performed on each developer client box installation that needed to be configured to access metadata from a Hadoop data source.

  1. Informatica developer needs to execute kinit command on the developer client box to get and cache the initial ticket-granting ticket from the KDC server. This requires providing appropriate keytab and krb5 configuration files to individual developers and asking them to execute the command manually before requesting metadata using the developer client. Since keytab files include sensitive information, distributing the same to each developer box appropriately and asking developers to execute these commands manually requires a lot of careful handling on the customer side.
  2. If the cluster is SSL enabled, developer needs to import the corresponding certificates in each developer client installation using keytool commands to import the certificates in the jre folder.
  3. Developer also needs to export the cluster configuration XML from Informatica Admin console and manually extract the zip file and place the same into the 'conf' folder under the appropriate Hadoop distribution folder on the developer client installation.
  4. Developer also needs to update the variable 'INFA_HADOOP_DIST_DIR' defined in 'developerCore.ini' file on each client box under the client installation if connecting to a Hadoop distribution other than the default Cloudera version.
  5. Finally, after performing the above steps (needed on each developer client box), developer can launch the import wizard for the data source in the developer client to import and save the metadata.

As apparent from the above steps, performing the above steps on each developer client box (customer may potentially have tens or even hundreds of developer client installations) is a big hassle. Metadata Access Service was introduced to ease the above configuration and also provide improved security architecture w.r.t metadata access for Hadoop data sources.


Metadata access using Metadata Access Service

Metadata Access Service is intended for enabling metadata access to Hadoop data sources(HDFS Files, HBase, Hive and, MapR-DB) from the developer client tool. This is a mandatory service that must be created before any metadata access from Hadoop sources listed can be performed via the developer tool. The service can be created using either Informatica admin console or through command line using infacmd tool.

Metadata Access Service needs to be configured only once by the Informatica Administrator (similar to how existing services like Data Integration Service used for data access by Informatica mappings). If there is a single metadata access service configured and enabled, it'd get picked up automatically by the developer client installations, else the default metadata access service can be selected once at the developer client level and the developer selection gets cached until changed. Metadata Access Service provides a lot of features and advantages compared to the accessing metadata directly from developer client tools.

  1. Metadata Access Service enables configuration of Kerberos specific attributes like keytab location, principal name at a single location.  There is no longer a need to run the kinit command on any developer client boxes since appropriate keytab file location and Service Principal Name can be provided in the MAS configuration in the Admin Console. This is also more secure as we no longer need to distribute and use sensitive information to developer boxes.
  2. Developer can configure multiple metadata access services either for load balancing purpose (to reduce the load on a single service process) or to connect a different Hadoop distribution type (Cloudera, Hortonworks, MapR etc) or a system with a different configuration (keytab, Service Principal Name) is desired. Hence, there is no need to perform steps like downloading cluster configuration files into localHadoop distribution folder on the developer client. Developer can select the appropriate Metadata Access Service name in the developer client as the default service for the current developer client session in case multiple services are configured (similar to how default DIS service is selected).
  3. Configuring access to SSL enabled clusters is also simplified as the SSL certificates for the clusters need to be imported (using keytool command) on a single node (where MAS is configured to run) and not on each developer client box.
  4. Developer can also enable the option to use 'logged in user as impersonation user' similar to DIS to enable current logged in user credentials in developer client box to be used while accessing any Hadoop resources.
  5. Support for centralized logging is enabled, hence, any metadata access related error message would also get captured and persisted in a centralized location (in addition to showing in a popup dialog box as earlier) just like other services like DIS and can be viewed (with features like filtering enabled) in Informatica Admin Console service log console in a similar manner. Without Metadata Access Service, the error messages were shown in a pop-up dialog only in developer tool but could not be retrieved later once the dialog box with an error message is closed by the developer.
  6. Metadata Access Service can be configured to interact with developer client tool over either http or more secure https protocol just like other Informatica services like DIS. Developer can configure the appropriate port (http/https) and keystore/truststore password/file locations (if https is enabled) as part of Metadata Access Service configuration through Admin Console or infacmd.
  7. Support for backup node is also enabled for high availability for Metadata Access Service. Hence, if the primary node where metadata access service runs goes down, the service should come back up on the backup node automatically.
  8. The local Hadoop distribution folders on the developer client boxes are now used during metadata access only if any metadata is accessed from the local file on the same box (where developer client box is installed) eg when a local avro or parquet file is used to import metadata without using a Hadoop File System connection object. Hence, the variable 'INFA_HADOOP_DIST_DIR' needs to be configured (or updated) only if metadata needs to be imported from a local file. In scenarios where a connection is used to import metadata, this variable is no longer required to be configured on the developer client side for metadata access. The size of Informatica Hadoop distribution folder on the developer client is also significantly reduced (by more than 1 GB) as most of the Hadoop distribution related jars/files are required to be deployed as part of only Informatica server-side installation.


'Metadata Access Service' provides a significant architectural improvement resulting in better security and easier configuration for Informatica Big Data Management client-side developer tool. This reduces the amount of time Informatica developers and administrator need to spend on configuring connectivity to Hadoop adapters like HDFS files, HBase, Hive and MapR-DB for importing metadata into the repository.
