lakeview is a visibility tool for AWS S3 based data lakes. Think of it as ncdu, but for Petabyte-scale data, on S3. Instead of scanning billions of objects using the S3 API (which would require millions of API calls), lakeview uses Athena to query S3 Inventory Reports.

QUESTION
following are my files for html, .ts and json . As json data was very extensive therefore i have just added a few states and their cities. my 1st dropdown is showing all states. Now I want to match my 1st dropdown's selected value of state with a key "state" in "cities" object in my json file so i can populate 2nd dropdown with cities relevant to that state. and I want to do this in function "getCitiesForSelectedState". please help me find solution for this.

parameter.
Make sure to compare your values safely.
If your value is not in the right type or has spaces or unwanted chars, this c.state == val
might not work.
You can use the trim
function to compare your value safely:
c.state.trim() == val.trim()

So I have two for loops, and one is nested inside another but the results they return seem to be running the first loop and returning its results than the nested loop. How could I make it run in a synchronous behavior? For example, all the topicData gets printed in a row instead of printing one topicData and moving on to the nested for loop. I'm not sure if this is the proper way to implement the async await. Any pointers would be appreciated. Thanks

Answered 2020-Feb-16 at 19:52There are couple of issues here
- You are trying to do callback style code in loops while you have promise methods available.
- You could also do things in parallel using
promise.all
- Because of callback style the code is very complicated
- You are awaiting where it is not required. For example in the callback
You can try to use this way

Answered 2018-Apr-27 at 08:181) First of all if your data is already stored in files per group id there is no reason to mix it up and then group by id using Spark. It's much more simple and efficient to load for each group id only relevant files
2) Spark itself parallelizes the computation. So in most cases there is no need for external parallelization. But if you feel that Spark doesn't utilize all resources you can:
a) if each individual computation takes less than few seconds then task schedulling overhead is comparable to task execution time so it's possible to get a boost by running few tasks in parallel.
b) computation takes significant amount of time but resources are still underutilized. Then most probably you should increase the number of partitions for your dataset.
3) If you finally decided to run several tasks in parallel it can be achieved this way:

I have a page on a website I'm building that has a comments feature. The website is like Yelp for campsites and each campsite in the collection in the mongo db has a field - comments - that stores the id of every comment posted on that campsite and the id refers to an object in another collection entitled comments. Adding, editing, viewing and deleting comments all works apart from when deleting a comment, the id of that comment is not removed from the comments array of its associated campsite.
Here is an example of a record for one campsite currently:

Install lakeview
Ensure you have an S3 inventory set up (preferably as Parquet or ORC)
Verify the table is registered in Athena
Run lakeview as a standalone Docker container: docker run -it -p 5000:5000 \ -v $HOME/.aws:/home/lakeview/.aws \ treeverse/lakeview \ --table <athena table name> \ --output-location <s3 uri> note <athena table name> is the name you gave in step 2, and <s3 uri> is a location in S3 where Athena could store its results (e.g. s3://my-bucket/athena/)
