HANA SPS07 Smart Data Access

  1. 1. What´s New? SAP HANA SPS 07 SAP HANA smart data access (Delta from SPS 06 to SPS 07) SAP HANA Product Management November, 2013
  2. 2. Scope of Delta from SAP HANA SPS 06 to SPS 07 New or Improved smart data access Features Support for new Remote Sources such as Oracle and MS SQL Extended DML to Insert/Update/Delete on Virtual Tables Calc View Support for Virtual Tables Deliver Generic Adapter framework to extend additional Remote Sources ‘Remote Caching’ for Hadoop sources Support for CLOB & BLOB data types hdbsdautil – utility to debug Remote Source configuration © 2013 SAP AG. All rights reserved. Public 2
  3. 3. New and Improved SDA Features
  4. 4. Expand Remote Source systems support With SAP HANA SPS 07 smart data access will support new data sources such as  Oracle 12c  Microsoft SQL Server ver11  Hadoop Hortonworks HDP 1.3 © 2013 SAP AG. All rights reserved. Public 4
  5. 5. Extended DML support on Virtual Tables • Support for inserting, updating, and deleting data in virtual tables. • The inserted data is transferred to the remote database on-the-fly. It is also updated transactionally on-the-fly and deleted on-the-fly transactionally from the remote database. • Insert/Update/Delete support is provided for the supported datasources. Limitations: No support of inserts/ deletes / updates for BLOB / CLOB and No support of correlated queries © 2013 SAP AG. All rights reserved. Public 5
  6. 6. Calc View support for Virtual Tables • When creating a calculation view, it will be possible to add virtual tables as data sources. • Virtual tables can also be referenced by the calculation scenarios. • The support for adding virtual tables in the calculation view can also be done from SAP HANA Studio. • Optimizations such as push down of filters is also supported is these Calc scenarios. Limitations: no support of aggregate / group by / order by function push down © 2013 SAP AG. All rights reserved. Public 6
  7. 7. Remote caching for Hadoop sources When SAP HANA dispatches a federated query to HIVE, it involves series of ‘map’ and ‘reduce’ job execution. This could take few minutes to hours to complete a query depending on the data size in Hadoop and the current cluster capacity. In most cases, the data in Hadoop cluster is not frequently updated and successive execution of map/reduce jobs might result in same tuples. As of SPS 07, HANA allows this result view to be materialized in the remote system thus avoiding the repetitive execution of the same query. This behavior can be controlled by hinting the optimizer to use remote caching. Syntax Select * from hive_activity_log where incident_type = ‘ERROR’ and plant =’001’ with hint (USE_REMOTE_CACHE) © 2013 SAP AG. All rights reserved. Public 7
  8. 8. Generic Adapter Framework • Add support for new ODBC data sources by providing connectivity configuration files CREATE SOURCE DB2sample adapter "odbc" CONFIGURATION FILE ‘dbs1.ini' using "Server=myDBsrv;Port=4100..." • Sample Properties file entries CAP_SUBQUERY : true CAP_SUBQUERY_GROUPBY : true CAP_SUBQUERY_SELLIST : true CAP_SUBQUERY_UPDATE : true CAP_ORDERBY : true CAP_ORDERBY_EXPRESSIONS : true CAP_ORDERBY_UNRELATED : true CAP_ORDERBY_UPDATE : true CAP_JOINS : true CAP_JOINS_OUTER : true CAP_JOINS_MIXED : true CAP_GROUPBY : true CAP_GROUPBY_ALL : true © 2013 SAP AG. All rights reserved. Public 8
  9. 9. Configuration Validation Utility - hdbsdautil • The utility check drivers and dependency files of given data source type. • Can also connect to remote database with given credential information and run query with/without result set display. • Syntax hdbsdautil -t <data source type> -S <DSN or string> [-U <username> [-P <password>]] [-Q <SQL>] [-nr] [-info] • Examples hdbsdautil -t tdodbc -S "dsn=td_dsn" -U test -P test -info Try to connect to a remote Teradata database with ODBC configuration in property file (e.g. ~/.odbc.ini) With username and password specified Dump ODBC information to console © 2013 SAP AG.
