2.0.2
10-23-2024
New features
๐งฌ Define your custom unique document identifier (applies to NoSQL targets only): from the Web UI it is now possible to define your own custom unique document key, by composing it with custom fields (you can even sort them manually), a prefix, a suffix and a custom value separator. As shown in the picture below, just toggle the Customize document key switch to begin building your own custom key template.
๐ On-the-fly data filtering: you can now specify filters to be applied to incoming data feed, meaning while data is on-flight, to filter out data not matching the desired filter rule. This initial release introduces the following filters:
-
=
, -
>
, -
<
, -
>=
, -
⇐
, -
!=
, -
in
, -
Not in
, -
Is null
, -
Not null
, -
Regex
: to be used likeDan.*
to filter out data just like you are applying aLIKE Dan%
SQL where clause to match your data.
This feature will be further extended to include additional filter types, rules, predicates and the ability to apply the filter at snapshot level to avoid sourcing unwanted data during snapshot tasks.

Improvements
๐๏ธ 2x performances improvement with same hardware resources: we went down optimizing payloads serialization, fine tuned algorithms and optimized the platform under different hardware setups, all of this has been achieved after thousands of benchmarks done in the past few months. With this release we’re bringing the first chunk of improvements for a smoother & faster replication experience. More to come.
๐๐ป IBM i series / AS400 agent: we carried out a major refactor of the source IBM i agent with the goal to lower its resources footprint: thanks to one of our customers we have been able to drastically reduce the agent’s CPU resources usage on the IBM machine level especially on low-CPW provisioned hardware. We went from 50% CPU consumption for an average CPU time of 15-30 seconds down to as low as 5% for 0.5 seconds avg. CPU time. This massive improvement has been measured on low-end hardware resources with ~18.000 provisioned CPW as well as on hardware with double the provisioned CPW. We can now proudly say that we have one of the fastest & lightweight IBM i source agents in the market.
2.0.1
10-10-2024
๐ Security:
-
TLS certificate support with issued JKS (Java key store);
From 2.0.1 onwards every connection established to and from the Core Hub is made with TLS encryption. Web UI is then reachable from https:// protocol when TLS is enabled. A self-signed HTTPS/TLS certificate is shipped with every new kit. Please request a new trial kit or contact support for upgrading from past versions. |
-
Container images no longer use
root
as predefined user within the container, highering security measures and enforcing the security perimeter of the application and its context;
๐ Connections pool (for JDBC’s agents): we’re paving the way for new features like prioritized entities, groups and much more. This release brings a whole new set of feaures around connection pool management such as how many entities within the same pipeline can run in parallel (by limiting how may connections can be opened towards the source). We will add a new chapter to our documentation to describe how to leverage this new functionality;
2.0.0

-
Improved Rest API endpoints;
-
