Re: code sample for cluster configuration

[Rajesh Kishore]

Thanks Pavel, I am aware about this code.
I am able to establish a cluster as well. I have following requirement:
>From my application - I want to retrieve/insert records on different
cluster server. My application code is single instance , my application
code should be unaware from which ignite cluster server its
retrieving/inserting the data.
Would just setting Ignition.setClientMode(true) is enough for this usecase,
would my application to push the data to one of the portioned cluster
server ?

Thanks,
Rajesh

Hi Rajesh,

There is a good sample with enabled persistance -
https://github.com/apache/ignite/blob/master/examples/src/main/java/org/apache/ignite/examples/persistentstore/PersistentStoreExample.java
Also documentation about Ignite persistance  presented in
https://apacheignite.readme.io/docs/distributed-persistent-store.

continuous query - changes from local server only

[Som Som]

hi.

I have a cache with cachemode = partitioned and 2 server nodes that share
parts of the cache data according to the affinity function. Then I run the
client node on one of the computers where the server node is located. How
to configure a continuous query on the client node to receive events only
from server nodes located on the same machine?

Re: Enable Kerberos on Ignite Kafka streamer / support for new consumer config

[jackson.dickson]

Thanks Andrew for your response.

As per this documentation (
https://docs.confluent.io/3.0.0/kafka/sasl.html#sasl-configuration-for-kafka-clients

 
), SASL auth is supported only for new Kafka consumers. The new kafka
consumers connect to the Kafka brokers directly instead of zookeeper


Below two security config are required to be specified in the consumers
configs which are only supported in the new Kafka consumer config.
security.protocol
sasl.kerberos.service.name

Refer -  https://kafka.apache.org/0100/documentation.html#oldconsumerconfigs
  

The ignite kafka streamer uses old consumer config
(kafka.consumer.ConsumerConfig). I get below errors in the log file if I
specify these new consumer configs.

code sample for cluster configuration

[Rajesh Kishore]

Hi,

I want to try a two node setup for Ignite cluster with native file based
persistence enabled .

Any samples, or pointer ?

Re: Enable Kerberos on Ignite Kafka streamer / support for new consumer config

[Andrey Mashenkov]

Hi Jackson,

Ignite supports kafka-0.10.0.1 version.
Kafka official docs has support some kerberos options [1].
So, it should be possible to enable Kerberos with certain options in
ConsumerConfig.

Re: Text Query question

[dkarachentsev]

Hi Jet,

Full text search creates Lucene in-memory indexes and after restart they are
not available, so you cannot use it with persistence. @QuerySqlField enables
DB indexes that are able to work with persisted data, and probably no way to
rebuild them for now.

Thanks!
-Dmitry
