Why does project reactor hang indefinitely when switchIfEmpty is used?

Background I’m using Spring Boot 2.2.1, project-reactor 3.3.0 and spring-data-mongodb 2.2.1 and I’m trying to load data from multiple collections. My code looks roughly like this: Flux.just(“type1”, “type2”, “type3”, “type4”) .concatMap { type -> reactiveMongoOperations.find<Map<String, Any>>(BasicQuery(“{‘type’: ‘$type’}”), “collectionName”) .doOnError { e -> log.error(“Caught exception when reading from mongodb: ${e::class.simpleName} – ${e.message}”, e) }.switchIfEmpty { log.warn(“Failed […]

Rolling average and sum by days over timestamp in Pyspark

I have a PySpark dataframe where the timestamp is in units of days. Following is an example of the dataframe (let’s call it df): +—–+—–+———-+—–+ | name| type| timestamp|score| +—–+—–+———-+—–+ |name1|type1|2012-01-10| 11| |name1|type1|2012-01-11| 14| |name1|type1|2012-01-12| 2| |name1|type3|2012-01-12| 3| |name1|type3|2012-01-11| 55| |name1|type1|2012-01-13| 10| |name1|type2|2012-01-14| 11| |name1|type2|2012-01-15| 14| |name2|type2|2012-01-10| 2| |name2|type2|2012-01-11| 3| |name2|type2|2012-01-12| 55| |name2|type1|2012-01-10| 10| |name2|type1|2012-01-13| […]

For example, in plyr::mapvalues, if I would like to change the values of carbin mtcars to type1, type2, type3 – I would do something like this: library(tidyverse) mtcars %>% mutate(carb = plyr::mapvalues( carb, from = c(“1”, “2”, “3”, “4”, “6”, “8”), to = c(“type1”, “type1”, […]

Getting null in finding average of double value inside array in MongoDB?

I am trying to find the average of double value inside an array in MongoDB but getting null value. The data is like this: { “_id”:””, “body”:{ “id”:”154476880″, “imp”:[ { “id”:”1″, “banner”:{ “w”:300, “h”:250, “battr”:[ 8, 9, 10 ] }, “bidfloor”:0.219057, “bidfloorcur”:”USD”, “secure”:0 } ], “app”:{ “id”:”2f61ead27d67″, “name”:”MyFitnessPal”, “bundle”:”341232718″, “storeurl”:”https://itunes.apple.com/app/id341232718″, “cat”:[ “IAB1”, “IAB1-5”, “IAB1-6”, “IAB1-7”, […]

Can I import and export same-name class and namespace simultaneously in TypeScript?

Consider class (e. g., ExampleUtil) in the file ExampleUtil.ts. Currently types which ExampleUtil uses, stored in the file ExampleUtil__TYPES.ts. No problems when import them into ExampleUtil.ts; currently, there is no need for namespace. When I begin to use ExampleUtil in other projects, it turned out that types from ExampleUtil__TYPES.ts is context-dependent and it’s better to […]

Apple turicreate always return the same label

I’m test-driving turicreate, to resolve a classification issue, in which data consists of 10-uples (q,w,e,r,t,y,u,i,o,p,label), where ‘q..p’ is a sequence of characters (for now of 2 types), +,-, like this: q,w,e,r,t,y,u,i,o,p,label -,+,+,e,e,e,e,e,e,e,type2 +,+,e,e,e,e,e,e,e,e,type1 -,+,e,e,e,e,e,e,e,e,type2 ‘e’ is just a padding character, so that vectors have a fixed lenght of 10. note:data is significantly tilted toward one […]
