kandi X-RAY | magellan Summary

magellan is a Scala library typically used in Big Data, Spark applications. magellan has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Magellan is a distributed execution engine for geospatial analytics on big data. It is implemented on top of Apache Spark and deeply leverages modern database techniques like efficient data layout, code generation and query optimization in order to optimize geospatial queries. The application developer writes standard sql or data frame queries to evaluate geometric expressions while the execution engine takes care of efficiently laying data out in memory during query processing, picking the right query plan, optimizing the query execution with cheap and efficient spatial indices while presenting a declarative abstraction to the developer. Magellan is the first library to extend Spark SQL to provide a relational abstraction for geospatial analytics. I see it as an evolution of geospatial analytics engines into the emerging world of big data by providing abstractions that are developer friendly, can be leveraged by anyone who understands or uses Apache Spark while simultaneously showcasing an execution engine that is state of the art for geospatial analytics on big data.

Foundation sticky nav jumps when scrolling fast in Safari

Asked 2021-Jan-27 at 21:48

I noticed that when I scroll upwards fast in Safari, the sticky nav jumps around, then I have to scroll slowly again to get it to click back into it's proper place. I'm using Foundation 6. Also, this is a new issue, as everything used to work just fine in Safari, but something must have changed in the past 4 months or so. See below for an example of the issue.

Here's the HTML for the nav bar. I haven't done anything special with the CSS.

You can get to the SOAP call by doing a couple of Deserialization calls.

Deserialize the json, main Json
Deserialzie the json, raw_response
Deserialize the xml, raw_response

How to rename changed files while merging branches and keep old versions?

Let's say that I have following file on my master branch

ANSWER

Answered 2019-May-23 at 17:20

There is nothing built in to Git to do this.

You can handle some cases by using git read-tree to do the merge in the index, without resolving any conflicting changes. But note that even git read-tree's 3-way merge will in some cases just pick one of the two endpoint versions of some file: if the merge base version (tree #1 as inserted into slot #1 in the index) of some file F matches one of the other two (staging slots 2 or 3), and does not match the version of F in the other of the two staging slots, git read-tree will collapse the three versions down to a single stage-zero slot, taking the modified file.

In other words, given your example with two different contents for truth.txt, we first need to know: what does the merge base version say? If the merge base version of truth.txt exactly matches one of the two branch-tip versions, then all Git merge operations will just automatically take the other version. Only when all three differ will Git leave all three in the index, so that you can achieve your desired result using some of Git's built-in helpers.

If that does not match up with your desires, you're stuck with building your own programs to deal with the various trees. Note that you can make your own temporary index and use git read-tree to fill it, then use git ls-files --stage on however many temporary index files you used, plus of course the real index file, to compare entities. That gives you a fast way to decide whether truth.txt is identical or different in any two trees read into any two index files.

(You could do all of this without using any of Git's internals, of course: just check out the commits in question in separate work-trees, and compare work-tree files.)

How to transform a DataFrame to and RDD[Point] instead of RDD[ROW]?

Asked 2019-Apr-19 at 19:13

I have a dataframe with many columns, that I have created from a csv file defining a schema. The only column I'm interest in is a column called "Point", where I defined a magellan Point(long, lat). What I need to do now, is creating an RDD[Point] from that dataframe.

Below is the code that I have tried, but it does not work since rdd is a RDD[Row] instead of RDD[Point].

If I understand correctly, you want the result to be of a custom class type which is Point instead of Row type
