kandi X-RAY | storm-scribe Summary

storm-scribe is a Java library typically used in Messaging, Pub Sub, Unity, Kafka applications. storm-scribe has no bugs, it has no vulnerabilities and it has low support. However storm-scribe build file is not available. You can download it from GitHub.
This is an implementation of a spout that receives data from Scribe. It is an example of a "push spout", in that data is pushed to it rather than the spout pulling data from somewhere else. This spout requires a fork of Scribe that allows for Zookeeper-based node discovery: https://github.com/traviscrawford/scribe. See http://groups.google.com/group/scribe-server/msg/c6d04c3b0ee25ddc for more details on how that works. This is an unreliable spout that doesn't guarantee data processing. With some more work, it can be extended to be reliable – see the note in ScribeReceiver.java. This spout mostly respects TOPOLOGY_MAX_SPOUT_PENDING. If the spout is deactivated (like as part of the topology shutdown), it will flush its internal queue of messages to the output collector (which may be more than TOPOLOGY_MAX_SPOUT_PENDING). This ensures that every message pushed to it is at least attempted to be processed. As explained above, with more work actual reliability could be added to the spout.

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...

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"
  }
}
