Does Liquibase have any plans to support for Apache Ignite in the near future?
I would like to use Liquibase along with Apache Ignite in a database proxy component that forms part of a micro-service architecture system we are building.
Yours is the first I have heard of anyone asking. Your best hope is to write your own Ignite plugin. The effort required to implement something like that would depend heavily on whether or not the dialect of SQL it uses is similar to an existing dialect, and whether there is an existing JDBC driver for Ignite.

We are planning to migrate our existing flow in Apache NiFi to Informatica PowerCenter. Could you guys please suggest whether it is feasible or not.
Please do also provide the possible challenges and what could be all the possible way to implement it.
I am expecting the proper solution.
We are analyzing ignite to use it in .NET platform, In Ignite document we can see there is some limitation on running cluster in Java and Thin Client in .NET. The list provided in the document doesn't mention about "Data Streaming". So would like to know whether "Data Streaming" is supported in "Mixed-Platform" or not ?
Yes, Data Streaming is supported in mixed-platform clusters, and you can do it from Ignite.NET Thin Client without any limitations.
P.S. The document is slightly outdated (fix on the way), Services are also supported in this scenario, you can make Java <-> .NET service calls in both directions, which some customers use extensively:
https://ignite.apache.org/docs/latest/net-specific/net-java-services-execution
This is my first question in this forum, so kindly forgive me for my mistakes.
Now, my query is regarding clustering in Netty Server 4.0.
We have one solution which was designed and developed in Netty Server. That time it was using multiple instances in a way so that clients were not effected if the sessions are not shared among them.
Now, in a different project while using the same solution we have come across a situation where we need to share and synchronized the JVM within multiple instances. Since, netty itself does not support JVM level clustering we are looking for a framework which will support Netty to run in cluster mode.
We are not supposed to put lot of efforts in re-writing the Netty Server code and other business login as it is serving the same purpose but we are looking for a configuration based framework to support clustering with Netty Server.
Some configuration based tutorial are really appreciated.
Thanks in advance and looking forward for responses.

Why do Apache Hive needs Apache Thrift? On the Thrift's site it says that it can compile in multiple languages, but I can't understand where does it fits and why do Hive need it.
Thanks
Cited from safaribooksonline:
Chapter 16. Hive Thrift Service
Hive has an optional component known as HiveServer or HiveThrift that
allows access to Hive over a single port. Thrift is a software
framework for scalable cross-language services development. See
http://thrift.apache.org/ for more details. Thrift allows clients
using languages including Java, C++, Ruby, and many others, to
programmatically access Hive remotely.
The CLI is the most common way to access Hive. However, the design of
the CLI can make it difficult to use programmatically. The CLI is a
fat client; it requires a local copy of all the Hive components and
configuration as well as a copy of a Hadoop client and its
configuration. Additionally, it works as an HDFS client, a MapReduce
client, and a JDBC client (to access the metastore). Even with the
proper client installation, having all of the correct network access
can be difficult, especially across subnets or datacenters.
Couldn't have said it better. Emphasis mine.
https://cwiki.apache.org/confluence/display/Hive/HiveServer
HiveServer is an optional service that allows a remote client to submit requests to Hive, using a variety of programming languages, and retrieve results. HiveServer is built on Apache ThriftTM (http://thrift.apache.org/), therefore it is sometimes called the Thrift server although this can lead to confusion because a newer service named HiveServer2 is also built on Thrift.
For more details on how to connect to hive server(thrift server) see the link above.
I am evaluating the Rich Ajax Platform (RAP) and I need to connect to a DB2 database (and perhaps others).
Having done a fair amount of J2EE work I usually fetch a DataStore object via JNDI and use that to connect to a database. The actual connection parameters are configured outside of the application and can be adapted for development, test and production environments.
-- How should I go about this from within a plugin in RAP?
-- What is the best way to handle connections in different enviroments?
-- I also don't want to include the DB2 JDBC jars in the plugin as they may differ slightly between development and production.
