Re: Pessimistic TXN did not release lock on a key, all subsequent txns failed

The issue you mention doesn't seem to be related to the issue we are having as, - The entire grid does not lock up as in the situation described in the bug - There are no threads blocked or locked when our key lock occurs - The bug seems to occur on Optimistic locking whereas our scenario occurs on

Memory Usage - OFFHEAP_TIERED Cache Memory Mode

Hi , We have a 3 node ignite cluster and have configured cache in OFFHEAP_TIERED memory mode with 2 back-ups. All the caches are configured as PARTITIONED cache. There are ~90 caches configured. Once all the cache is loaded, we collect cache stats from Ignite Visor console : 'cache -a'. *CLARIFI

ODBC driver error during SELECT query for string data type

Re: Few questions

1) Yes, unless some data have been evicted from Ignite cache. 2) Sure, this is expected: IGFS in dual modes always tries to reflect the underlying file system contents. 3) This sounds strange. In DUAL_ASYNC mode it is possible that changes made to IGFS appear in underlying file system with some d

Re: ODBC driver error during SELECT query for string data type

Hi, Can you provide a bit more info about your code and library you have used to connect to ODBC? We have not tested our driver with python so it seems very interesting, but the only thing I can point you to right now is that our ODBC driver uses UTF-8, not UTF-16 encoding. I'm not sure if encodi

Re: Memory Usage - OFFHEAP_TIERED Cache Memory Mode

Hi, VisorCmd shows avarage value of some first cache rows, after multiplies over all elements count. It does not got exact cache size, only estimate. Furthermore in a latest Ignite version 2.0, work with memory radically changed[1] and to make estimation by elements does not possible. If you sow

Hi, Could you please explain what you do? Are you get some exception on start? Usually enough download Ignite, extract it and run ignite.(but/sh). If necessary modify default-config.xml. -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/PCF-tile-for-Ignite-tp1246

Thanks a lot for your help. Now I get much clear. Could you help me to understand what are the "client nodes". Do I need to change configuration of the cluster, or I can simply set up "client nodes" by changing codes within the spark application code? Currently, I am running ignite with embedded m

Re: Understanding Swap Space feature-- how it works?

Basically, swap space is another storage layer. You have on-heap, off-heap and then swap. So in case of on-heap mode only entry will be written in swap when it's evicted from cache due to eviction policy. With off-heap enabled it will be written to swap when it's evicted from there due to off-heap

Re: Few questions

Thx Ivan.. appreciate your help... Regarding point 3, I was specifically referring to the IgniteCache and not Igfs. Sorry if my jargons are a bit incorrect in the context, but per my understanding, ignite has ~ 1) in memory data grid (ignite cache) 2) ignite file system 2 sits on top of 1 (rather

Re: Few questions

Hi, Pranay, to be honest, I'm not sure I 100% understand the question. Yes, IGFS internally implemented by 2 caches (meta & data), but these 2 caches do not assume any direct modifications, that is, modifications done otherwise than through IGFS API. On Fri, May 19, 2017 at 7:12 PM, Pranay Tonpay

Race Condition at Grid Startup

Hi, I have a chicken-and-egg problem. I am trying to create a ConsulIpFinder – which uses our Consul-based service discovery under the covers. (I asked about this without luck here: http://apache-ignite-users.70518.x6.nabble.com/ConsulIpFinder-TcpDiscoveryIpFinder-issue-td12974.html ) My problem

Re: Race Condition at Grid Startup

Hi, Is there any reason why you can't register the nodes with Consul from the code of the IP finder? This is what other cloud based IP finders (aws, google compute engine, jdbc, etc) do in Ignite. The point here is that if the ip finder returns non null list of adresses then the nodes should be re

Re: Race Condition at Grid Startup

Thank you for responding. I cannot see how either of these options will help me. I need to defer the IpFinder until my system is entirely alive and the Consul Health Checks pass. Similarly Ignite must be started on all of the Nodes, and they would all be waiting on each other. So the IpFinder wi

Chris, then I need a bit more time to dive into this topic next week. Can you share the source code of the ip finder? Yakov, would you join the thread as well? Denis On Friday, May 19, 2017, Chris Berry wrote: > Thank you for responding. > > I cannot see how either of these options will help m
