Getting vlingo to run on YugaByte DB

General
1

This is a working thread to get the vlingo platform on YugaByte DB. This requires vlingo-symbio-jdbc to work against YSQL.

Here are the steps I did so far (updating these as I go):

  1. Install YugaByte DB
    Install YugaByte DB on a local machine with YSQL running on port 5433 (the default). Next create the database for running the tests:

    $ psql -U postgres -p 5433 -h 127.0.0.1
postgres=# create database vlingo_test;

  2. Clone the vlingo-symbio-jdbc repo

  3. Build the repo using mvn -DskipTests package

  4. Run the unit tests

Need a little help with building this. I rebased to the latest version of the repo (GitHub - vlingo/xoom-symbio-jdbc: The VLINGO XOOM SYMBIO implementation for JDBC for Reactive storage using Event-Sourcing, Key-Value, and Object storage.) and am hitting the following error when trying to build:

$ mvn -DskipTests package

The only changes I have are to src/main/java/io/vlingo/symbio/store/common/jdbc/postgres/PostgresConfigurationProvider.java (these are not causing the issue):

-            "jdbc:postgresql://localhost/",
+            "jdbc:postgresql://localhost:5433/",
             "vlingo_test",  // database name
-            "vlingo_test",  // username
-            "vlingo123",    // password
+            "postgres",  // username
+            "",    // password

Hi Karthik,

[Fixed the XML – didn’t realize it is markdown.]

Sorry, I think you may have gotten a daily snapshot for some refactoring that we are in the middle of. Can you change your pom.xml file to point to Maven Central? See the following:

--------- change this -------------

      <repositories>
        <repository>
          <id>jcenter</id>
          <url>https://jcenter.bintray.com/</url>
        </repository>
      </repositories>

--------- to this -------------

      <repositories>
        <repository>
          <id>central</id>
          <name>Maven Repository Switchboard</name>
          <url>http://repo1.maven.org/maven2</url>
        </repository>
    </repositories>

Let me know if that fixes things.

Yup that did it, thanks! Got me unblocked. Running the tests now, will post with an update.

Ok I ran the tests, the only feature we need is INSERT ... ON CONFLICT UPDATE ... by doing the following:

$ mvn test 2>&1 > /tmp/vlingo.log

$ grep 'ERROR:' /tmp/vlingo.log

I see only the following error in the logs:

ERROR: INSERT ON CONFLICT option not supported yet

Let me get back on the timeframe for adding that option.

That’s great news and looking forward to the update!

Hey @Vaughn_Vernon,

Completely forgot about this… gave it another go. Hitting build errors, help please:

Hi @karthik It’s been a few months since our previous contact. It’s possible that you need to update the full platform source and rebuild, or at least update your pom.xml vlingo-* dependencies to 0.8.3.

If you need to pull the latest platform source you can do the following:

$ cd vlingo-platform
$ ./gradlew
...
$ mvn clean install

The gradlew pulls the latest source from all repositories. The mvn clean install will build the entire platform and install the .jar files into your local Maven repository (~/.m2).

Hi @karthik

I have just published a new release on Bintray and Sonatype (Maven Central lags for some hours). I suggest updating to current release: 0.8.4

Let me know how it goes.

Best,
Vaughn
