Re: SparkRDD with Ignite

Thanks for the reply, Val. Lookslike the issue is with having "null" fields in the database. Read that null fields are handled in Ignite 1.8 release. Is that right ? Thanks, Vidhya From: vkulichenko Sent: Wednesday,

Re: SparkRDD with Ignite

It depends on how big your data set, where the data is coming from, etc. I don't think Ignite is a bottleneck here. -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/SparkRDD-with-Ignite-tp9160p9319.html Sent from the Apache Ignite Users mailing list archive

Hi, This configuration is incorrect: 127.0.0.1:47100..47509 172.26.116.67:47100..47509 First of all, since you're building a distributed cluster, you should not use loopback here. Put real addresses that discovery component binds to. Second of all, 47100 is a port for communication, not for

Anil, JDBC driver actually uses the same Ignite API under the hood, so the results are fetched in pages as well. As for the query parser question, I didn't quite understand what you mean. Can you please give more details? -Val -- View this message in context:

I have a partitioned cache size of 15000 and 4 server nodes with backup of 1. Through visor each node is showing a size of around 7500. Also, if I decrease or increase backup, the cache size on each node stays the same. I think since it is partitioned mode ...size of each node should be 15000/4
