Re: Transaction operations using the Ignite Thin Client Protocol

[Ivan Pavlukhin]

It worth noting that users should be cautious with SQL transactions.
As fair SQL transactions are supported only for TRANSACTIONAL_SNAPSHOT
mode which are still kind of experimental feature [1].

Re: Transaction operations using the Ignite Thin Client Protocol

[Ilya Kasnacheev]

Hello!

As we have discussed privately, ODBC is actually the C++ thin SQL client,
and it supports transactions since 2.7.

C++ code should look forward to using ODBC to communicate with Ignite.

Re: Transaction operations using the Ignite Thin Client Protocol

[Igor Sapego]

Ivan,

You are right. Though now we have transactions support in thin client
protocol,
It is only now implemented for Java. Also, C++ thin client yet to support
SQL.

Best Regards,
Igor

Re: Transaction operations using the Ignite Thin Client Protocol

[Ivan Pavlukhin]

Igor,

Could you please elaborate whether C++ thin client is going to have
transactions support in 2.8? AFAIR, it was implemented only for Java
thin client.

The ticket says “Fix version: 2.8” so I would assume it would be available 
then. Currently planned for late January.

Re: Transaction operations using the Ignite Thin Client Protocol

[dkurzaj]

Hello,

Since this improvement : https://issues.apache.org/jira/browse/IGNITE-9410
is resolved, I'd assume that it is now possible to do SQL transactions using
the C++ thin client, though I'm not sure it is yet since I did not find
documentation about that. Would someone happen to know more about this
subject?

Thank you!

Dorian

Re: Transaction operations using the Ignite Thin Client Protocol

[kotamrajuyashasvi]

Hi

Thanks for your response.

The project I'm working on requires many C++ processes running on a machine
with each C++ process to perform cache operations on Ignite Cluster
transactionally. Hence Each Individual C++ process has to start an Ignite
C++ Client node with in its process. But there will be a large number of C++
processes running and starting Ignite C++ Client node with in each of the
process would be memory Intensive. Also there are some other issues while
working with Ignite C++, which could not be replicated/reproduced here and
due to time constraint we are not able to focus on this replication issue.
Hence exploring other options.

Hi,

Is there a reason why you do not want to use the C++ client that comes with
Ignite?

Re: Transaction operations using the Ignite Thin Client Protocol

[Denis Magda]

+ dev list

Igniters, Pavel,

I think we need to bring support for key-value transactions to one of the 
future versions. As far as I understand, a server node, a thin client will be 
connected to, will be the transaction coordinator and the client will simply 
offloading everything to it. What do you think?

Re: Transaction operations using the Ignite Thin Client Protocol

[kotamrajuyashasvi]

Hi

In Ignite ODBC all operations are sql based and as you mentioned sql
transactions feature is not available yet. So cannot use it. So just
exploring all light weight C++ client  options available which support
Ignite Transactions.

Re: Transaction operations using the Ignite Thin Client Protocol

[Evgenii Zhuravlev]

Right now, this client implemented only for .NET, but it's not even
released yet.

I'm not sure about transactions since design document doesn't contain any
information about it.

BTW, why you don't want to use ODBC from C++?

Re: Transaction operations using the Ignite Thin Client Protocol

[kotamrajuyashasvi]

Hi

according to 
https://cwiki.apache.org/confluence/display/IGNITE/IEP-9+Thin+Client+Protocol

we can perform cache operations like get(),put() etc using thin client
protocol which uses tcp socket communication with the Ignite server. I would
like to know if similarly we can send a request to start a transaction or
committing / rolling back transaction.

Hi

Thanks for your response. 
I would like to know if Transaction operations on Ignite cache at key-value
level(not SQL) can be performed using the Thin Client Protocol.

Hi,

Transactional SQL is not available yet, it will be fully available when

Transaction operations using the Ignite Thin Client Protocol

[kotamrajuyashasvi]

Hi

I would like to perform Ignite Transaction operations from a C++ program
using the Ignite Thin Client Protocol. Is it possible to do so ? If this
feature is not available now, will it be added in future ?
