I wanted to connect and confirm on changes for this PR.
https://github.com/apache/ignite/pull/6490
Do you think keeping the change for PlatformConfigurationUtils.java will
cause regression on the .NET component or C++ components?
Jira :
Take the amount of cashback calculation or payments authorization as
examples of compute tasks with local SQL. In the first case, all
transactions are collocated per account and a bank needs to calculate the
cashback monthly by broadcasting the task that executes special logic
across all accounts
Yes, I understand that it is straightforward and, may be, naive approach.
Which is why I'm asking how to do map-reduce on cache C data in Ignite with
proper partition pinning.
About Predefined/Implemented aggregate - I'm not sure I agree that we can
predict everything. It is real perk of Ignite
Dmitriy,
First, what kind of cumulative metric can it be? A lot of cumulative
metrics can be compared using SQL. MIN, MAX, AVG are simple ones. For
more complex ones I can think about user-define aggregate functions
(UDAF). We do not have them in Ignite so far, but can introduce them.
Second,
Hi Ivan, Igniters, imagine you need to scan all entities in the cluster.
Ideally, you don't want to de-serialize all of entries, so you can use
withKeepBinary(). e.g. you need a couple of fields and get some cumulative
metric on this data. You can send compute to all cluster nodes and run
there
Hi, Ilya!
I've fixed the flaky test.
Could you have a look?
Thank you!
