setup scheduled export on google appe




If you are using the google app engine you might get this message from the google.


Hello Cloud Datastore Customer,

We're writing to let you know that the Datastore Admin backup feature is being phased out as of February 28, 2018, in favour of the generally available managed export and import for Cloud Datastore. Please migrate to the managed export and import functionality at your earliest convenience. To help you make the transition, Datastore Admin will continue to be available over the next 12 months prior to the shutdown date of February 28, 2019. 
I am writing this post to show how to set schedule export.
[ I am showing the steps described by the google at this link.  Scheduled-export ]

Enable the billing for google cloud service

Ensure that you are using a billable account for your GCP project. Only GCP projects with billable accounts can use the export and import functionality. 
You can Set your billing details at console.cloud.google.com/billing


Make sure about billing details

Create a bucket for backup

Create a bucket inside cloud storage for your project.
 [ where you want  to export your datastore backup]

Go to storage in the cloud console
Go to storage in the cloud console
You can find the storage in the sidebar of the console.

Create a new bucket where you want to export the datastore backup. and make sure bucket type is regional or multi-regional.  and the location is the same where you project is hosted for me its us-central-1

Schedule export does not support the cold line or near line for schedule export.

Assign the Cloud Datastore Import Export Admin role

The role can be assigned from the IAM & Admin Section of the cloud console

Copy Application [ Service ] Files From Google Cloud Doc

Copy this three file from the Google Cloud doc as it is.

  • app.yaml
  • cloud_datastore_admin.py
  • cron.yaml
Update only url and schedule in the cron.yaml according to your need.
url: /cloud-datastore-export?namespace_id=&output_url_prefix=gs://BUCKET_NAME
In our case 
url: /cloud-datastore-export?namespace_id=&output_url_prefix=gs://backup-demo-purpose


Deploy the service


Deploy the service through the gcloud. 
[ It was failing when i was using app engine to deploy]
cmd : gcloud app deploy app.yaml cron.yaml
In case you have multiple projects you can use --project to deploy service to the specific project
cmd  : gcloud app deploy app.yaml cron.yaml --project=demo-project


Verify Deployment

Make sure that service is working. After deployment of the app you will be able to see the job inside your projects Appengine > Task queues > crons

Task Queues
Task Queues

Run the cron ( using the run button at this time for testing) to verify and make sure status is Success

Firebase - update a spacific fields of single element of object of array in firestore

Firebase - update a spacific fields of single element of object of array in firestore  Its actully advisable to use map instead of array when ever it is possible. But, there are cetain cases where you don't have option to do so.  For example, you are directly saving the response from some outer source without any modification and they send you an array. In this case you will have array to work with. Firestore does not support array here is why  "bad things can happen if you have multiple clients all trying to update or delete array elements at specific indexes. In the past, Cloud Firestore addressed these issues by limiting what you can do with arrays " For more details information you can refer to Kato Richardson post Best Practices: Arrays in Firebase .  Firestore document having array [ used from stackoverflow question ] Suppose you have array of object something like shown in array. Now you want to update endTime field of the object on the index [1]

Sciter : GUI Application with Golang using HTML/CSS

GUI library for golang sciter This is the words from Sciter's Web site, Sciter brings a stack of web technologies to desktop UI development. Web designers and developers can reuse their experience and expertise in creating modern looking desktop applications. Various GUI frameworks offer different UI declaration and styling languages, such as QML and  XAML (Microsoft WPF) . On the contrary, Sciter allows using time proven, robust, and flexible HTML and CSS for GUI definition and GPU accelerated rendering.   Before using sciter I already tried other alternatives but none of them was satisfactory as an example first i tried andlabs / ui  library   i already have written a post on it. You can read it on post gui programming with golang .  But this library is still under construction and has no support for production apps. Secondly, I go for electron but the problem was my simple calc like the app was of size 150mb. Which is 15mb of go and other was the e
