Valentin Kulichenko commented on IGNITE-16244:
----------------------------------------------
After updates, examples fail with a deserialization error in the client
protocol. To reproduce:
# Build from branch {{{}ignite-16244{}}}: {{mvn clean install -DskipTests
-Dcheckstyle.skip}}
# Unzip {{target/apache-ignite-3.0.0-SNAPSHOT.zip}} and switch to the folder.
# Run {{./ignite init}}
# Start a node: {{./ignite node start
--config=examples/config/ignite-config.json my-first-node}}
# Open the {{target/apache-ignite-3.0.0-SNAPSHOT/examples}} project in an IDE.
# Run any of the examples under {{table}} or {{tx}} package.
# Observe the exception shown below.

> Update examples for Ignite 3
> ----------------------------
>
> Key: IGNITE-16244
> URL: https://issues.apache.org/jira/browse/IGNITE-16244
> Project: Ignite
> Issue Type: Improvement
> Components: examples
> Affects Versions: 3.0.0-alpha3
> Reporter: Valentin Kulichenko
> Assignee: Valentin Kulichenko
> Priority: Major
> Labels: ignite-3
> Fix For: 3.0.0-alpha4
>
>
> With the current advancements in Ignite 3 functionality, examples look
> outdated and should be updated.
> The following changes should be made:
> # Use DDL instead of the convoluted {{createTable}} API to create tables.
> # Add examples for POJO-based views (we can use the existing
> {{RecordViewExample}} and {{KeyValueViewExample}} as a basis).
> # Add transactional API example(s).
