cachet | Go client library for Cachet

I need to implement a function that simply purges the database of all data except for a few tables. Given how the code is written so far, it would be easier to do that than to implement an outside function that actually deletes the entire database file and creates a new one.

I want to do this on one prepared statement, so that I can avoid code bloat by having multiple statements and executing them in sequence. I would also like to do it in a single transaction using begin and commit just in case. What I tried is this:

I need to understand if there is any difference between the below two approaches of caching while using spark sql and is there any performance benefit of one over the another (considering building the dataframes are costly and I want to reuse it many times/hit many actions) ?

1> Cache the original data frame before registering it as temporary table

df.cache()

df.createOrReplaceTempView("dummy_table")

2> Register the dataframe as temporary table and cache the table

df.createOrReplaceTempView("dummy_table")

sqlContext.cacheTable("dummy_table")

Thanks in advance.

In our software we have something like a cache inside a table of a database hosted on a Microsoft SQL-Server (2008 R2 to 2019). Now I have to debug some lines of code which only run, when this cache is empty. Otherwise the data comes from the cache and the code I need to debug doesn't run.

Since I'm sick of always manually deleting the content of this cache table before I can debug again, I'm looking for a way to make this cache table read-only for a while.

I can't change the code which is actually writing data to this cache table, so I'm looking for a way to achieve my goal with only using the SQL Management Studio, preferably running a TSQL script to switch on the read-only-ability and another script to switch it off again.

Googling for that I found several ways to accomplish that, but unfortunately all the ways I googled raise an error, which prevents our software to run along.

My preferred solution would be a trigger on my cache table, something like this:

There are a lot of similar questions here, but none answers the problem.

When using image_picker, barcode_scanner or other plugins which open their own activities everything works well until I use either the "cancel" button or the "back"-Button. My app crashes as soon as I hit the cancel-button with the following error log: (I used image_cropper to show this error, but image_picker and barcode_scanner create similar errors)

My map is functioning properly until I search for a nearest store location via zip code and try to click on a result's title in the generated panel to show the infoWindow of that corresponding title.

In other words, I want to be able to click the search result titles and when you do, it opens the infoWindow on the map marker associated with the title.

Click the map marker to show the infoWindow works fine. Click the search result in the list of results generated after searching, does not.

I'm using geoJSON to load the locations.
