Re: Ignite Rest API is not working

There is a chance that port 8080 was busy and it was bound to the next port. I'd recommend checking Ignite logs to make sure that rest was started and check the port. Evgenii пт, 14 июн. 2019 г. в 19:47, Kishan : > I want to use REST API provided by ignite. > > I have downloaded the ignite binar

Re: too many dirty pages

Hi, It's not a warning, it's just an INFO message about writing checkpoint to the disk. The reason for this checkpoint was that there were "too many dirty pages". Here is how Ignite persistence works: https://cwiki.apache.org/confluence/display/IGNITE/Ignite+Persistent+Store+-+under+the+hood Best

Re: exceptions in Ignite node when a thin client process ends

Hi, This message is absolutely unharmful, however, I agree that server node shouldn't print this exception since nothing wrong happened there. I've created a ticket in Jira for fixing this behavior: https://issues.apache.org/jira/browse/IGNITE-12032 Evgenii чт, 1 авг. 2019 г. в 09:33, Matan Lev

Re: Rebalancing only to backups

Hi Abhishek, That's how it works now if you have enabled Persistence. Actually, that's the main reason why BaselineTopology was introduced - we don't want to move a lot of data between nodes if we know that node will return soon after a failure: https://apacheignite.readme.io/docs/baseline-topolog

Re: distributed sql join not working as mentioned in documentation

Hi, To make work this query, you can add one where clause or join condition in the query, for example: where c.id = city_id;. I don't really understand why do you want to run a fully distributed cross join on these tables - it doesn't make sense, moreover, it will lead to the a lot of data movemen

Re: Map Reduce over cache items, where values are sequences

Hi, To parallelise everything properly, I would recommend starting an affinityCallable per partition(1024 by default). Inside this compute job, you can collect information for the certain partition only using ScanQuery(or SQLQuery) пт, 27 сент. 2019 г. в 18:09, Stas Girkin : > Hello everyone, >

Re: Improving Get operation performance

Hi Viktor, It looks like you're running 3 server nodes on the same physical machine, right? How do you run Cassandra benchmarks? Do you use the same 2 machines? How many Cassandra instances do you have? Also, how much memory do you have on this machine? Best Regards, Evgenii ср, 27 нояб. 2019 г

Re: Improving Get operation performance

Victor, Then, I would recommend to check if you have a swapping enabled in OS. If you have only 75gb on the machine and you started 3 nodes with 14 gb off heap and something like a 16gb heap each, probably OS started a swapping process, which will affect a performance. Additionally, there is no n
