Re: remote ignite server and L4(for loadbalacing) with java thin client
Hello, Thank you so much!.
I have 1 more question.
I use IgniteClient API in my application.(singleton)
when i start my application I regist IgniteClient bean using SpringFramework
and declare ClientConfiguration address like
ClientConfiguration cfg = new
ClientConfiguration().setAddresses("34.1.21.122:12800",
"34.1.21.122:12800");
Is there any way to add new ClientConfiguration address without my
application restart??
I'm considering using L4 between my application and ignite server node.. but
also L4 should be restart.
Is it possible to auto scale out java client thin level??

Re: apache-ignite_2.8.0-1_all.deb package has older version of openjdk as dependency
I guess it can be targeted to 2.8.1 if there any scope space left. > On 6 May 2020, at 07:27, rakshita04 wrote: > > Hi Team, > > We are using apache-ignite for our C++ application based on debian > 10(buster).

Thanks Petr. When can we expect 2.8.1 .deb package with newer openjdk dependency? -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Hello! Come to think of it, maybe we can just depend on java-sdk meta-package? Can you file an IGNITE JIRA ticket about that?

Re: remote ignite server and L4(for loadbalacing) with java thin client
Hello,
Currently, there is no way to add a new address without the client restart.
But there is a feature under development [1], perhaps, it will be useful
for your case.

Re: apache-ignite_2.8.0-1_all.deb package has older version of openjdk as dependency
are you talking about oracle-java8-installer? mentioned in control file of your package? actually we are able to manually compile platform/cpp code using openjdk-11. So wanted to check with you if there is any specific reason for using openjdk-8 for .deb released package? -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
Create table if not exists does not works in cocurrent case
Hello.I test creating same table in two threads.Here is my test code:
public class ConcurrentCreateTable {
private static Connection conn;
private static Connection conn1;
public static void main(String[] args) throws Exception {
initialize();
new Thread(new Runnable() {
@Override
public void run() {
while (true) {
try (Statement stmt = conn.createStatement()) {
stmt.execute(
"CREATE TABLE IF NOT EXISTS city1(ID
INTEGER,NAME VARCHAR ,PRIMARY KEY(ID)) WITH \"template=replicated\";");
stmt.execute("DROP TABLE IF EXISTS city1");
} catch (SQLException e) {
e.printStackTrace();
}
}
}
}).start();
new Thread(new Runnable() {
@Override
public void run() {
while (true) {
try (Statement stmt = conn1.createStatement()) {
stmt.execute(
"CREATE TABLE IF NOT EXISTS city1(ID
INTEGER,NAME VARCHAR ,PRIMARY KEY(ID)) WITH \"template=replicated\";");
stmt.execute("DROP TABLE IF EXISTS city1");
} catch (SQLException e) {
e.printStackTrace();
}
}
}
}).start();
while(true) {
}
}
private static void initialize() throws Exception {
Class.forName(Config.IGNITE_DRIVER);
final Properties props = new Properties();
conn = DriverManager.getConnection(Config.IGNITE_URL, props);
conn1 = DriverManager.getConnection(Config.IGNITE_URL, props);
}
}
It throws table already exists error.Does ignite not allow to cocurrently
create tables?

Re: deployment pattern
Hi, Yes you are correct. If you are able to co-locate the services on the same node as the data, performance will be better, and network round-trips will be avoided. Thanks, Alex -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
Re: Create table if not exists does not works in cocurrent case
Hi,
You are correct. If the requests are simultaneous, the error will occur. A
very small delay(see below), will prevent this.
This exception is informational in nature, and could safely be ignored.
Try this for the second thread
while (true) {
* Thread.sleep(100);*
try (Statement stmt = conn1.createStatement()) {
stmt.execute(
"CREATE TABLE IF NOT EXISTS city1(ID
INTEGER,NAME VARCHAR ,PRIMARY KEY(ID)) WITH \"template=replicated\";");
stmt.execute("DROP TABLE IF EXISTS city1");
} catch (SQLException e | InterruptedException e) {
e.printStackTrace();
}
Thanks, Alex
