Re: Ignite with Spring Cache on K8S, eviction problem

I have something like in this gist. I cant share everything but in get there is just request to DB. Evict is the same and I need to have this in the separate method because sometimes I need to evict for list of ids. I know that I can't call this method directly from the same class because of how

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

Thanks Andrew. The new consumer config enable Kafka clients to connect directly to the Kafka brokers. kafka-clients 0.10.x support both style. I believe you would need another ConsumerConfig type like ZKConfig. -Jackson -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Snapshot backup of Ignite native persistance data

Ignite with mariadb

Hi, Can Ignite be used with Mariadb? When attempted (via jdbc url: jdbc:mariadb://localhost:3306/db1?user=root=password) Ignite throws exception that it is not able to find suitable jdbc driver for the Mariadb. What is the recommended way of integrating Mariadb with Ignite? Thanks, Sumanth

Re: Ignite with mariadb

Do you want to use mariadb as Ignite's cache store (3-rd party persistence)? You can use whatever you want if you implement your custom cache store. You might also try using out-of-the-box CacheJdbcPojoStore. It already supports DB2, Oracle, SQK Server, H2 and MySQL. It looks like mariadb should

Hi Ivan, Thanks for you reply. I have some follow up questions. 1. What is the behaviour of cluster when it is in ignite.cluster.active(false) state? Does it throw error when a cache seek operation is performed? Or does it wait for cluster to become active again? 2. How can I reliably know if

Okay I am trying to reproduce. It hasn't got stuck yet, but the client got disconnected and reconnected recently. I don't think it is related to GC because I am recording GC times and it does not jump up that much. Could the system get slow on a lot of io? i see this in the ignite log:

It's hard to determine the problem by these messages. I don't see anything unhealthy regarding persistence - checkpoint start is a regular event. There were cases when excessive GC load on client side seriously affected throughput/latency of data streaming. You may consider playing with the
