You're confusing object schema and SQL schema. By adding those field via binary object builder, you amended the former, but not the latter. SQL schema stayed the same, with (a,b) being key fields not presented in value. I would not recommend to do this, as you can end up having weird issues (for ex

Hi, thanks for replying- Actually, even though we can use the SQL facilities to inspect the caches, the intended usage is to have Java clients, and possibly using the jcache api to access the data; so I really need to use cache.get(key). I looked further into this; for this very same cache, if da

Hello! 1. Note that you will have problem writing to caches when topology changes. Why not just query ignite.cluster(), expose node traits as node.attributes()? 2. Having 100 servers should not be a problem. It is recommended to have long-lived clients in this case, as opposed to creating and tak

Re: ignte cluster hang with GridCachePartitionExchangeManager

Hi Evgenii, In the document mentioned on Result Set Lazy Load, if result set is too big to fit in the available memory, then it can lead to prolonged GC pauses and even OutOfMemoryError. 1. Is it referring to the on heap memory of the client application or the off heap memory? 2.

Hi, get() operation from client always go to the primary node. If you run compute task on other nodes, where each will do get() request for that key, it will read local value. REPLICATED has many other optimizations, for example for SQL queries. Thanks! -Dmitry -- Sent from: http://apache-igni

Re: Grid state check before it's completely caught up

Hi, You can, for example, set SYNC rebalance mode for your replicated cache [1]. In that case all cache operations will be blocked unless rebalance is finished, and when it's done you'll get a fully replicated cache. But this will block cache on each topology change. [1] https://ignite.apache.or
