kandi X-RAY | aggregateD Summary
aggregateD is a network daemon which listens for metrics including gauges, counters, histograms, sets and events, sent over http and sends aggregates to InfluxDB. InfluxDB is a promising, but young time series database, aggregateD is intended to bring dogstatsD like functionality to Influx. aggregateD can accept metrics either as JSON over HTTP or in the dogstatsD format sent over UDP. Therefore, aggregateD can be deployed in the same manner as either satsD or dogstatsD. That is, it can either run on the same host as instrumented applications or it can run on a dedicated host that multiple clients communicate with.

QUESTION
I want to filter a table showing only the rows where total is between ± 3 standard deviations from the average.
The query I'm using is this:
...ANSWER
Answered 2021-Jun-12 at 09:37Try something like this. I have added some sample data as your question has not given any data and schemas. You need to use group by clause when you use Aggregate functions in our queries. I suggest you to refer to Group by and aggregate functions in SQL server.

QUESTION
I have a big problem when I want to make a view.
...ANSWER
Answered 2021-Apr-27 at 08:08Just add GROUP BY YEAR(FIN_RESERVATION)
to the end of your query or change it to MIN(YEAR(FIN_RESERVATION))
- you can also use max. If you didn't do these things and instead changed the mode MySQL would simply arbitrarily pick one of the year values anyway
Only full group by is a good thing
QUESTION
I have a Dataframe that can have multiple columns of Array type like "Array1", "Array2" ... etc. These array columns would have same number of elements. I need to compute a new column of Array type which will be the sum of arrays element wise. How can I do it ?
Spark version = 2.3
For Ex:

Answered 2021-Jun-11 at 15:59Consider using inline
and higher-order function aggregate
(available in Spark 2.4+) to compute element-wise sums from the Array-typed columns, followed by a groupBy/agg
to group the element-wise sums back into Arrays:

QUESTION
When reading about CQRS it is often mentioned that the write model should not depend on any read model (assuming there is one write model and up to N read models). This makes a lot of sense, especially since read models usually only become eventually consistent with the write model. Also, we should be able to change or replace read models without breaking the write model.
However, read models might contain valuable information that is aggregated across many entities of the write model. These aggregations might even contain non-trivial business rules. One can easily imagine a business policy that evaluates a piece of information that a read model possesses, and in reaction to that changes one or many entities via the write model. But where should this policy be located/implemented? Isn't this critical business logic that tightly couples information coming from one particular read model with the write model?
When I want to implement said policy without coupling the write model to the read model, I can imagine the following strategy: Include a materialized view in the write model that gets updated synchronously whenever a relevant part of the involved entities changes (when using DDD, this could be done via domain events). However, this denormalizes the write model, and is effectively a special read model embedded in the write model itself.
I can imagine that DDD purists would say that such a policy should not exist, because it represents a business invariant/rule that encompasses multiple entities (a.k.a. aggregates). I could probably agree in theory, but in practice, I often encounter such requirements anyway.
Finally, my question is simply: How do you deal with requirements that change data in reaction to certain conditions whose evaluation requires a read model?
...ANSWER
Answered 2021-Jun-07 at 01:20First, any write model which validates commands is a read model (because at some point validating a command requires a read), albeit one that is optimized for the purpose of validating commands. So I'm not sure where you're seeing that a write model shouldn't depend on a read model.
Second, a domain event is implicitly a command to the consumers of the event: "process/consider/incorporate this event", in which case a write model processor can subscribe to the events arising from a different write model: from the perspective of the subscribing write model, these are just commands.

QUESTION
Spring Integration - Producer Queue capacity limitations
We are using Remote partitioning with MessageChannelPartitionHandler to send partition messages to Queue(ActiveMQ) for workers to be pick and process. The job has huge data to process , many partition messages are publishing to queue and the aggregator of response from replyChannnel is failing with timeout of messages as all messages cant be processed in a given time. We also tried to limit messages published to queue by using queue capacity which resulted into server crash with heap dump generated due to memory issues of holding all these partition messages in internal memory.
We wanted to control the creation of StepExecution split itself , so that memory issue doesn’t occur. Example case is around 4k partition messages are being published to queue and whole job takes around 3hrs.
Can we control the publishing of messages to QueueChannel?

You need to increase your timeout or add more workers. The Javadoc of MessageChannelPartitionHandler is clear about that:
