Re: Ignite TryGet - cache data not found intermittently
Hello Charlin, As I wrote, the first option is the `full sync` mode: CacheConfiguration.WriteSynchronizationMode = CacheWriteSynchronizationMode.FullSync [1] The second one is disabling reading from backups: CacheConfiguration.ReadFromBackup = false [2] [1] https://ignite.apache.org/releases/latest/dotnetdoc/api/Apache.Ignite.Core.Cache.Configuration.CacheConfiguration.html#Apache_Ignite_Core_Cache_Configuration_CacheConfiguration_WriteSynchronizationMode [2] https://ignite.apache.org/releases/latest/dotnetdoc/api/Apache.Ignite.Core.Cache.Configuration.CacheConfiguration.html#Apache_Ignite_Core_Cache_Configuration_CacheConfiguration_ReadFromBackup Thanks, S. ср, 12 июн. 2024 г. в 12:58, Charlin S : > Hi Slava Koptilin > > Thanks for your email. > > Cache configuration used at time of cache creation in C# code.

Re: Ignite TryGet - cache data not found intermittently
Hi Slava Koptilin
Thanks for your email.
Cache configuration used at time of cache creation in C# code. Please
suggest me if any configuration changes required in cache level or grid
level
CacheConfiguration.CopyOnRead=false
CacheConfiguration.EagerTtl=true
CacheConfiguration.CacheMode = CacheMode.Partitioned
CacheConfiguration.Backups = 1

Re: Ignite TryGet - cache data not found intermittently
Hi Charlin,
I mean that it might be "well-known" behavior if you use `primary sync`
mode and the `readFromBackup` property equals `true` (which is `true` by
default).
The first option, to overcome this problem, is using `full sync` mode. In
that case, the update request will wait for the write to complete on all
participating nodes (primary and backups).
The second option, that can be used here, is to use 'primary sync' and set
'CacheConfiguration#readFromBackup' flag to false. Ignite will always send
the request to the primary node and get the value from there.
Thanks,
S.

Re: Ignite TryGet - cache data not found intermittently
Hello Charlin,
Could you share your cache configuration? Specifically, what values are
used for `readFromBackup` and `writeSynchronizationMode`.
Thanks,

Re: Ignite TryGet - cache data not found intermittently
Hi Pavel,
Thanking for your email.
> Perhaps something else is involved here, another thread or node changing
the value?
I checked the application log and another thread did not do any other
operation for this particular data between this 45 seconds time gap.
no chance for changing cache key value as this data is able to be read
after some time.
I will keep you posted for small projects.
Thanks & Regards,
Charlin

Hi All,
I am unable to fetch data from cache by reading by
key.intermittently (very rarely).
Ignite version: 2.10
Cache mode: Partition
Client : C# with Ignite thick client
Scenario:
My C# application received a request for cache data insertion
@ 09:09:35 and successfully insertion initiated at application side.
Thereafter @ 09:10:21 C# application received a request to read cache
data for the same key and Ignite TryGet could not fetch data.
Note: We are able to get cache data by the same key after some time.
Cache creation code
var IgniteCache= IIgnite.GetCache("cacheModel")
.WithExpiryPolicy(new ExpiryPolicy(
TimeSpan.FromMinutes(60),
TimeSpan.FromMinutes(60),
TimeSpan.FromMinutes(60)
));
Cache data insertion code
IgniteCache.Put(cacheKey, (T)data);
Cache data reading code
IgniteCache.TryGet(Key, out var value);
Thanks & Regards,
Charlin
Re: Ignite TryGet - cache data not found intermittently
> Put and tryget are in two different methods called one after another
That would be a very apparent bug in Ignite, and I don't see anything like
that in JIRA or release notes.
Perhaps something else is involved here, another thread or node changing
the value?
Please prepare a small project that we can run to reproduce the issue.

Re: Ignite TryGet - cache data not found intermittently
Hi,
Put and tryget are in two different methods called one after another one
with some time gap based on work flow process
We felt Ignite 2.10 okay for us.
Thanks and Regards

Re: Ignite TryGet - cache data not found intermittently
- Do you run Put and TryGet on the same node?
- Do you have a reproducer?
- Ignite 2.10 was released 3 years ago, have you tried a newer version?
