Oracle Database 21c New Feature: Full Text Columns with In-Memory

 Oracle Database 21c New Feature: Full Text Columns with In-Memory.

This blog post by Andy Rivenes Product Manager at Oracle highlights this exciting new feature in 21c to the already expansive array of features boasted by Oracle Database In-Memory.

Here is a brief summary.
  • In the previoius versions, Oracle Database In-Memory did not support predicates for non-scalar documents e.g. if you were using domain indexes for Oracle full text index, XML Search Index, or JSON Search Index then these were not populated in the IM column store. This resulted in degradataion of performance for searching non-scalar types of data. 
  • Now in Oracle Database 21c In-Memory, there is new support  to store, or populate, these types of domain-specific indexes.
  • The new 21c In-Memory Full Text Columns feature provides a faster way to perform searches on text type data.
  • Full Text Columns do not require maintaining a separate Oracle Text index.
  • Full Text Columns now support various types of application workloads within the Oracle converged database.

Cheers.

Oracle Analytics Cloud uses Oracle Database In-Memory for faster results

Oracle Analytics Cloud uses Oracle Database In-Memory for faster results.

This blog post by Bret Grinslade Senior Product Director at Oracle highlights this exciting new announcement by Oracle Analytics Cloud.

Here is a brief summary.
  • In Oracle Analytics Cloud, the new in-memory engine provides Automatic Caching, which is in-turn built on Oracle Database In-Memory.
  • Built on Exadata and the advanced Oracle Database query engine, Automatic Caching for datasets offers query performance improvements without any changes to existing customer datasets.
  • In-Memory is very helpful for larger datasets or datasets with complex calculations.
  • The new caching engine is available in Oracle Analytics Cloud in Oracle Cloud Infrastructure (OCI).
  • Some of the best performance improvements are for more complex scenarios e.g. Datasets with multiple users using shared workbooks see query performance improving as more queries are run.
  • Users can noticeably observe the most performance benefits when employing complex filters and calculations. 
  • These performance benefits now come with the same security and ease-of-use that, you get with an Oracle Analytics Cloud dataset.
  • The best part of this new combination is that customers already have it.
  • Starting with Release 6.1, all customers using Oracle Analytics Cloud on OCI Gen2 have been automatically upgraded: You can continue to use datasets with Automatic Caching, and when the data is reloaded, it will use in-memory technology.
Enjoy this blog post announcing this exciting new combination now available for Oracle Analytics Cloud.

Cheers.
