kandi X-RAY | eventbus-performance Summary

eventbus-performance is a Java library typically used in Messaging, Pub Sub applications. eventbus-performance has no bugs, it has no vulnerabilities, it has build file available and it has low support. You can download it from GitHub.
A collection of benchmarks for event-bus libraries in Java space used for implementations of pub/sub pattern. A benchmark runs a specified workload against a unified interface that implements an adapter of the actual event-bus implementations. Benchmark contents (workloads) are described below. For each run of a benchmark you can find a plot of the runtime performance of each library and a textual comparison of the avg. performances. >> Please note: Currently the only candidates are Guava EventBus and MBassador. This is because including the other available libraries (see earlier versions of this repository) would have required a more complex EventBus abstraction in the tests. In previous versions they had been included but their performance was so poor in comparison to Guava and MBassador that continued support of their interface seemed not worth the effort. They also did not support polymoprphic event delivery such that results were not exactly comparable. The results of the benchmarks of the most recent versions is illustrated below. Older versions can be found in the projects result folder. For a discussion of the results, see the end of this README.

QUESTION

Build JSON content in R according Google Cloud Pub Sub message format

Asked 2022-Apr-16 at 09:59

In R, I want to build json content according this Google Cloud Pub Sub message format: https://cloud.google.com/pubsub/docs/reference/rest/v1/PubsubMessage

It have to respect :

{
  "data": string,
  "attributes": {
    string: string,
    ...
  },
  "messageId": string,
  "publishTime": string,
  "orderingKey": string
}

The message built will be readed from this Python code:

def pubsub_read(data, context):
    '''This function is executed from a Cloud Pub/Sub'''
    message = base64.b64decode(data['data']).decode('utf-8')
    file_name = data['attributes']['file_name']

This following R code builds a R dataframe and converts it to json content:

library(jsonlite)
data="Hello World!"
df <- data.frame(data)
attributes <- data.frame(file_name=c('gfs_data_temp_FULL.csv'))
df$attributes <- attributes

msg <- df %>%
    toJSON(auto_unbox = TRUE, dataframe = 'columns', pretty = T) %>%
    # Pub/Sub expects a base64 encoded string
    googlePubsubR::msg_encode() %>%
    googlePubsubR::PubsubMessage()

It seems good but when I visualise it with a json editor :

enter image description here

indexes are added.

Additionally there is the message content: enter image description here

I dont'sure it respects Google Cloud Pub Sub message format...

Answered 2022-Apr-16 at 09:59

Not sure why, but replacing the dataframe by a list seems to work:

library(jsonlite)

df = list(data = "Hello World")
attributes <- list(file_name=c('toto.csv'))
df$attributes <- attributes

df %>%
  toJSON(auto_unbox = TRUE, simplifyVector=TRUE, dataframe = 'columns', pretty = T)

Output:

{
  "data": "Hello World",
  "attributes": {
    "file_name": "toto.csv"
  }
}
