What's new in IBM Db2 Event Store Version 2.0.1.2

The following features are introduced in Version 2.0.1.2:

Communication between worker nodes requires DNS entries for the worker nodes
An issue where Db2 Event Store members that interconnect would prevent inter-member communication when there were no DNS entries for the OpenShift worker node names has been addressed. This can occur in some cloud environments that do not allow the user to manage the DNS entries for the worker nodes. Users attempting to run Db2 Event Store Version 2.0.1.1 should contact support if they encounter this issue.
Connection to Db2 Event Store from Python notebooks within Watson Studio Local
An issue that would prevent Python notebooks from running within Watson Studio Local to access a Db2 Event Store instance within the same IBM Cloud Pak for Data cluster has been addressed. A script was created to modify the Python java gateway configuration to address this issue in Db2 Event Store Version 2.0.1.1. Users running Db2 Event Store Version 2.0.1.1 should contact support if they require assistance to address this issue.
Time to live feature
An issue with the definition of the Time to live feature that would prevent it from being used has been addressed. Users can specify a time to live duration for database records. After the specified time period, these records are no longer available. The value is set when the table is created. For more information, refer to CREATE TABLE statement. Time to live is only available to Parquet tables. Only consolidated data is subject to time to live. Consolidation happens after 64mb of data has been inserted for a given shard or after a defined time period which defaults to 1 hour.

The Time Series toolkit allows you to process time series data (i.e. like website visit numbers) to identify trends and predict future values based on those trends.

What's new in IBM Db2 Event Store Enterprise Edition Version 1.1.3

The following features and changes were introduced in Version 1.1.3:
Installation changes
The following changes were introduced for the installation, upgrade, and uninstall features:
New parameter required when installing
When you run the IBM Db2 Event Store installation, you must specify the --compute-path parameter, which specifies the partition where you want to store data during computations. The partition requires an minimum of 100 GB of space on an solid-state drive. For more information on running the installation, see Install IBM Db2 Event Store Enterprise Edition.
Upgrade is not supported
You cannot upgrade to IBM Db2 Event Store Enterprise Edition Version 1.1.3 from a previous version of IBM Db2 Event Store. You must install IBM Db2 Event Store Version 1.1.3. For more information, see Install IBM Db2 Event Store Enterprise Edition.
Interactive command-line installation supports only single-node clusters
Previously, you could use the interactive command-line installation method to install a single-node cluster or a multi-node cluster. However, in IBM Db2 Event Store Version 1.1.3, you can use this installation method to install only single-node clusters. If you need to install IBM Db2 Event Store Version 1.1.3 in a multi-node cluster, refer to Install IBM Db2 Event Store Enterprise Edition.
JDBC API updates

What's new in IBM Db2 Event Store Enterprise Edition Version 1.1.2

The following features were introduced in Version 1.1.2:
Support for JDBC APIs
Starting with IBM Db2 Event Store Version 1.1.2, you can use JDBC APIs to connect to and query the tables in your database.

To connect to your JDBC applications, you must use a JDBC hive driver.

Restriction: The JDBC APIs do not support creating a database or table or inserting data to the database.

For more information, see JDBC API guide for IBM Db2 Event Store

New database table parameter for data lifecycle management
When you create a table, you can optionally specify the ibm.eventstore.ttl.hours parameter, which determines how long data persists in the table before it automatically expires.
Restriction: This parameter is available only from the client application APIs. You cannot specify this parameter through the REST API or the web-based interface for creating a table.

For more information, see the IBM Db2 Event Store Define and Ingest API guide.
