NullPointer Exception in Continuous Query

Hi, I am getting this exception in logs but not sure on which cache it is happening. Logs does not help me identifying the cache either. Apologies to ask here without much details but just wondering if someone know what are the chances to get this exception. I have set of caches and CacheMode is

Re: What is the most efficient way to scan all data partitions?

When running on AWS, I found that what the "disk" that you are writing to is the most critical issue for Ignite. EC2 instances with local SSDs have about 20x the write rate as a multiple 3 TB GP2 problems, and using actual disks (e.g., EBS) for Ignite Persistence storage is a non-starter.

Re: Backup and Restore of Ignite Persistence

Hi, Yes Ignite store the data into files. For every cache entity could exist some primiry node and optionally several backups node. It could be configured in CacheConfiguration. Read about it you can here: https://apacheignite.readme.io/v1.1/docs/primary-and-backup-copies For example you have 3

Re: What is the most efficient way to scan all data partitions?

Hi, It's normal that writing to disk is causing the degradation. You can do several optimizations to speed up writting to disk: https://apacheignite.readme.io/docs/durable-memory-tuning https://apacheignite.readme.io/docs/performance-tips However you can try to test your example with next Defaul

Re: Ignite web console query

There won't be an option to disable it (as there is no option to turn off MogoDB right now). The persistence will keep user credentials as well as statistics on long running queries. -- Denis On Tue, May 8, 2018 at 10:08 PM, vbm wrote: > Hi Denis, > > Just curious to know, what will happen if n

Re: Inconsistency reading cache from code and via REST?

Hi, qryexe doesn't work correct. At some reason it ignores _key and _value in 2.4. You can use qryfldexe as it was describe here: http://apache-ignite-users.70518.x6.nabble.com/Example-of-SQL-query-td21427.html BR, Andrei -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: slow restart of ignite (with persistence enabled)

Are you trying to stop the cluster or a node? If the former, then you can use control.sh to deactivate the cluster before stopping the nodes. On Tue, May 8, 2018, 7:39 PM Randall Harmon wrote: > @dharvey - no, cluster is not deactivated. > > @anton - 26gb of data is under ignite data directory

Re: Example of SQL query

Hi again, We already discussed about it recently. At the moment some things works incorrect in 2.4: 1)Rest API only support String as key and value. And looks like you can't use affinity key on strings for the same issue. But if you can setup it using AffinityKeyMapper anotation: public stat

Backup and Restore of Ignite Persistence

hi, I am planning to have some important tables on Apache Ignite Persistence and therefore am looking for best practices and recommendations around backup and restore of Ignite Persistence layer. As I understand, Ignite stores data in standard files. Will just taking a backup of these files suf

What is the most efficient way to scan all data partitions?

Hi devs, I have a dataset that needs to be iteratively processed which is larger than the available total cluster memory. So I am using ignite native persistence and use compute broadcast method distribute processing logic. This works really well on small data (which can fit in memory) but is sig
