kandi X-RAY | xds Summary
Implementation of Envoy's dynamic resources discovery xDS REST. xDS is fundamentally an HTTP service that is hit by every Envoy process to get its state of listeners (LDS), clusters (CDS) and subsequently each cluster's endpoints through (EDS).

QUESTION
I have a range input to reveal the number of questions the user wants. After they changed the range input's value, the user presses the submit button. Then a form is appended. Everything is good from here. But now I want the appended forms to have different IDs, for example, the first form to have the id "form1", the second form to have the id "form2", etc. I can't find a way to give each of the appended form different ids.

QUESTION
Incremental xDS is a variant of xDS where updates only contain resources added/changed/removed.
As far as I understand, for resource types other than Listeners and Clusters, delivery of changes is incremental already in the SotW variant and deletion is indicated by a lack of a reference from parent resources.
Does this mean that the benefits of incremental xDS only apply to the LDS and CDS APIs?
...ANSWER
Answered 2021-Apr-30 at 19:17You are correct in saying that Incremental is designed to perform Deltas on current resource snapshots within the Envoy management server.
LDS and CDS obviously receive benefits from incremental, but the protocol is a bit more nuanced than you think. The other resource xDS servers DO show performance benefits as the subscription model is quite a bit different than SOTW. Some functionality did carry over into incremental xDS, but quite a bit changed internally. We are looking to add performance benchmarks inside of go-control-plane once this PR goes in: https://github.com/envoyproxy/go-control-plane/pull/387.
SOTW xDS will still send all resources that envoy requests regardless. Incremental operates on a diffing mechanism that will only send changes to clients that the server believes are needed. I would recommend reading through the merged control plane code for incremental to see how it works under the hood. If you have any more questions feel free to reach out to me in the envoy slack!
I would be happy to come back and report real metrics in a test environment once that code merges upstream :)
QUESTION
I am trying to open a netcdf file using rioarray:
import rioxarray
import xarray
import raster
xds = rioxarray.open_rasterio(file, crs='+proj=latlong', masked=True)
but:
type(xds)
list
and xds has none of the attributes or methods of an xarray.
xds_lonlat = xds.rio.reproject("epsg:4326")
AttributeError Traceback (most recent call last) in ----> 1 xds_lonlat = xds.rio.reproject("epsg:4326")
AttributeError: 'list' object has no attribute 'rio'
clipped = xds.rio.clip(mask.geometry, mask.crs, drop=False, invert=True)
AttributeError Traceback (most recent call last) in ----> 1 clipped = xds.rio.clip(mask.geometry, mask.crs, drop=False, invert=True)
AttributeError: 'list' object has no attribute 'rio'
Can anyone advise?
...ANSWER
Answered 2021-Feb-24 at 21:08I recently encountered this when I was opening a netCDF (with rioxarray) that had multiple variables. Since it returns a list, you would not expect it to have any of the rioxarray attributes or methods.
The documentation for the function is here: https://corteva.github.io/rioxarray/stable/rioxarray.html
One of the return types is List[xarray.Dataset]
, so I think this behavior is expected.
My guess is that you want one of the entries in the list like xds=xds[0]
, though it's hard to know without having more information about the file that you are opening.
QUESTION
I'm using the current bundled binaries from https://github.com/excelsior-oss/xds (as of 12/6/2020) with just the most basic Hello World MOD file:
...ANSWER
Answered 2020-Dec-12 at 21:15To build a binary, use: xc =a =make HelloWorld.mod
The above is found in https://github.com/excelsior-oss/xds/blob/master/Sources/Doc/Comp/src/usage.tex . It is unfortunate that XDS did not put PDFs of their documentation on github. I suggest building the documentation from their LaTeX files.
Edit: I since learnt that the Wayback Machine has archived the XDS documentation here: https://web.archive.org/web/20060705213825/http://www.excelsior-usa.com/xdsdoc.html
QUESTION
I have this code and when I put the anchor (arrow img) outside, .MultiCarousel
div it doesn't work. I didn't write the code but I think I should change something in JavaScript. I want the anchor outside the container div but with the same functionality. I am not very familiar with JavaScript so I don't know what to change. Can someone help?
ANSWER
Answered 2020-Sep-30 at 08:34The problem is that the click()
function is searching for the parent element of the arrow key button, which it expects to be the .MultiCarousel
div in order for the rest of the code to work. So when you place the arrow keys outside of the .MultiCarousel
div a different parent will be found and your slider will not work.
In this case you could use the jQuery siblings()
function to find the .MultiCarousel
div, as the arrow key buttons are now siblings.
The same goes for the ResCarousel()
function. It expects the arrow key buttons to be children of the .MultiCarousel
div. So you can also use siblings()
here.

QUESTION
I'm trying to export data in a LINQPad script and keep receiving Out of Memory exception. I feel like the script is doing all 'streamable' actions so not sure why I'm getting this.
The main loop of the code looks like the following. A few notes:
1) The first query returns around 60K rows profileDB.Profiles.Where(p => p.Group.gName == groupName).Select( d => d.pAuthID )
2) The second query for each pAuthID
returns rows in a the database where one field is a Xml blob of data stored in a string field. It is not that big...< 500K for sure. Each pAuthID
row could have as many as 50 rows of FolderItems. The query is profileDB.FolderItems.Where(f => f.Profile.pAuthID == p && ( folderTypes[0] == "*" || folderTypes.Contains(f.fiEntryType) ) ).OrderBy(f => f.fiEntryDate)
3) I only write a single line to the result pane when the processing starts.
4) The script runs for a long time, throwing exception when the output file is around 600-700MB. Huge I know, but it is a requirement that we dump out all the data into Xml.
5) The WriteFolderItems
function/loop will be pasted below the main loop.
6) I call XmlWriter.Flush
after each xDataDef element.
