Simba DynamoDB JDBC Driver with SQL Connector Release Notes 
==============================================================================

The release notes provide details of enhancements, features, known issues, and
workflow changes in Simba DynamoDB JDBC Driver 1.1.3, as well as the version 
history. 


1.1.3 ========================================================================

Released 2019-11-15

Enhancements & New Features

 * [DDBJ-231] Upgraded AWS SDK
 
   The JDBC 4.1 and 4.2 versions of the driver now use version 1.11.673 of the
   AWS SDK. Previously, these drivers used version 1.11.15 of the SDK. As a
   result of this SDK upgrade, these drivers now support connections to a 
   wider range of AWS regions.
   
   The JDBC 4.0 version of the driver still uses AWS SDK 1.11.15.

 * [DDBJ-230] Upgraded Jackson library

   The JDBC 4.1 and 4.2 versions of the driver now use version 2.10.1 of the 
   Jackson JSON parser library. Previously, these drivers used version 2.9.9 
   of the library.
   
   The JDBC 4.0 version of the driver has been updated to use jackson-
   databind-2.9.7.6 instead of jackson-databind-2.7.9.3, but continues to use 
   jackson-dataformat-cbor-2.9.7. Newer versions of these libraries are not 
   compatible with JDK 1.6.


Resolved Issues 
The following issue has been resolved in Simba DynamoDB JDBC Driver 1.1.3.

 * [DDBJ-226] The driver returns 255 as the maximum length of string columns.
 
   This issue has been resolved. You can now configure the maximum string
   column length allowed by the driver, and specify a value that is greater 
   than 255. To do this, set the StringColumnMaxLength property. For more
   information, see the Installation and Configuration Guide.


Known Issues 
The following are known issues that you may encounter due to limitations in 
the data source, the driver, or an application. 

 * The following SQL features are not supported:
    - Queries without table names (for example, SELECT 1)
    - Sorting or filtering on binary data
    - The INSERT, UPDATE, and DELETE statements
    - The CREATE, DROP, and ALTER table operations

 * The following JDBC features are not supported:
    - Transactions
    - Batch operations

	
Workflow Changes =============================================================

The following changes may disrupt established workflows for the driver. 

In addition to changes that are already implemented in the current version of 
the driver, this section describes potentially disruptive changes that will be 
implemented in a future version of the driver, so that you can plan 
accordingly.


Upcoming ---------------------------------------------------------------------

 * [DDBJ-219] Removing support for JDBC 4.0 (Java 6)

   Beginning in April 2020, the driver will no longer support JDBC 4.0 (Java 
   6). For a list of supported JDBC versions, see the Installation and 
   Configuration Guide.
