# Striim 3.9.8 documentation

## What's new in Striim 3.9.8

The following features are new in Striim 3.9.8.

### Dashboards

• The MeetupMap sample application demonstrates the Vector Map visualization using a live source to map real-time data from all over the world.

• The SAMPLE BY option allows you to reduce the amount of data in an overloaded visualization while preserving the distribution of data in the full data set (see Defining dashboard queries).

### Application development

• CREATE EXTERNAL CACHE allows lookups from database tables that contain more data than can be cached in memory.

• The Field Enricher event transformer provides a graphical way to create joins (see Using event transformers).

• The SAMPLE BY option allows you to specify the maximum number of events to be returned by a CQ or to return a specified percentage of the total (see CREATE CQ (query).

• Streams can be partitioned using statements (see Adapting TQL applications for multi-server deployment).

• When exporting applications containing passwords or other encrypted property values, you can choose to remove those values or to add a second level of encryption with a passphrase that will be required on import.
