Bulk Inserts via SQLAlchemy and Flask-SQLAlchemy

Problem

I ran into an issue today where I had to perform a bulk insert into a postgres DB. I was already using SQLAlchemy and Flask-SQLAlchemy to manage the connections to the db and I didn't want to have to use things like psycopg2 directly.

Solution

Note: SQLAlchemy provides an ORM. It isn't just an ORM. That is an important thing to be kept in mind. This means that you can bypass choose to not use the ORM layer when you don't want it. The idea with an ORM is to track changes to objects and when you have a case like that is when you'd use the ORM. In a bulk upload scenario, you don't need to track changes to objects. All you care is that everything be pushed into the DB.

WAL-E needs to be installed on all machines, masters and slaves.

How to install WAL-E

Only one machine, the master, writes WAL segments via continuous archiving. The configuration for the master postgresql.conf is:

archive_mode = on
archive_command = 'envdir /etc/wal-e.d/env wal-e wal-push %p'
archive_timeout = 60

import axios from 'axios';
// You can use any cookie library or whatever
// library to access your client storage.
import cookie from 'cookie-machine';

axios.interceptors.request.use(function(config) {
  const token = cookie.get(__TOKEN_KEY__);

  if ( token != null ) {
    config.headers.Authorization = `Bearer ${token}`;

# you can make a text file of request times (in ms, one number per line) and import it here, or you can use a probability distribution to simulate request times (see below where setting req_durations_in_ms)

# parallel_router_count is only relevant if router_mode is set to "intelligent"

Uploading Large Files

NOTICE: The OneDrive API now has native supported for large file uploads. Instead of using BITS, consider using the OneDrive API upload method instead!

Note This is preliminary documentation and is subject to change as we evolve the OneDrive API.

OneDrive handles uploading large files by supporting the BITS protocol.

/**
 * Created by Guy Blank on 3/9/17.
 *
 *  This is a sample provides an API to send & receive messages to and from the React-Native WebView (using postMessage/onMessage WebView API).
 *  A sample project that uses the bridge is available here https://github.com/blankg/rn-webview-bridge-sample
 *
 *  webViewBridge.send('functionToInvoke', {mydata: 'test'}, function(){console.log('success')},function(){console.log('error')});
 *
 *  The API is designed to be similar to the Cordova exec API so migration to it should be almost seamless.
 *  The API also provides solution to a React-Native WebView bug in iOS which causes sending consecutive postMessage calls to override each other.
