Re: How many Caches/Tables we can create/query in parallel?

For maximum throughput you might want to consider IgniteDataStreamer rather than SQL. If you create your cache in Java or XML you could also avoid indexes entirely. There are lots of options here depending on your use case. In any case, I would urge you to measure the performance before (and

Re: How many Caches/Tables we can create/query in parallel?

I thought it's obvious that, SQL table return in O(log n) with n being number of elements in BTree. Our task being write intensive, If all the threads are inserting data to same tree then rebalancing and accessing time would be affected right? So for this sake, if we divide each thread's SQL data

Try this, you just need the multicast group (must be the same on clients and servers within same cluster): PIE

Yes it is best to put all server addresses into this section:

Re: Restarting the Main node when it goes down

Ignite will try to connect to each address specified in the addresses section and establish a connection. In the case of a multicast ip finder, it will use a multicast group to scan for nodes. In general one node needs to discover another and establish a socket connection on a specified

How many Caches/Tables we can create/query in parallel?

We created a task which crawls website. We have an SQL table, where the application writes data while crawling website. But the application has several threads running in parallel, each thread working on a certain website. The amount of data that is being generated on that SQL table is huge and we

Re: How many Caches/Tables we can create/query in parallel?

I’m not sure that your assumption that separate tables/caches will improve performance is true. Have you benchmarked it? To directly answer the question: there’s not really a limit, but you might want to consider using Cache Groups to minimise the overhead of hundreds of tables. > On 15 May
