streaming

问题 Many AWS reference architectures for serverless real-time analytics, suggest pushing processed data from Lambda to S3 through Kinesis Firehose. e.g. https://aws.amazon.com/blogs/big-data/create-real-time-clickstream-sessions-and-run-analytics-with-amazon-kinesis-data-analytics-aws-glue-and-amazon-athena/ Why can’t we push data from Lambda to S3 directly? Isn't it better to avoid complexity and additional cost by skipping the mediator Kinesis Firehose component? Is there any problem with

问题 In my previous question(Spark Structured Streaming dynamic lookup with Redis ) , i succeeded to reach redis with mapparttions thanks to https://stackoverflow.com/users/689676/fe2s I tried to use mappartitions but i could not solve one point, how i can reach per row column in the below code part while iterating. Because i want to enrich my per-row against my lookup fields kept in Redis. I found something like this, but how i can reach dataframe columns and add new column looking up to Redis.

问题 Suppose I want to stream video captured by my webcam to an Amazon AWS EC2 Instance for the purposes of image processing in the cloud. How would one do this? The only means for file transfer that I am aware of, is scp to copy files to the remote host. I have no idea where to begin in regards to streaming video to AWS EC2. Google turned up nothing for me. Any ideas? 回答1: Here is what worked. There are likely many other methods. 1) Create a free tier Amazon AWS EC2 instance with Ubuntu Server 16

问题 I'm trying to parse a large file (tens of GB) streaming using Nom 5.0. One piece of the parser tries to parse numbers: use nom::IResult; use nom::character::streaming::{char, digit1}; // use nom::character::complete::{char, digit1}; use nom::combinator::{map, opt}; use nom::multi::many1; use nom::sequence::{preceded, tuple}; pub fn number(input: &str) -> IResult<&str, &str> { map( tuple(( opt(char('-')), many1(digit1), opt(preceded(char('.'), many1(digit1))) )), |_| "0" )(input) } (Obviously,
