With the development of NoSQL, HBase gradually become the mainstream of the NoSQL system products. The advantages of HBase is very obvious, but defect is also very obvious. These weaknesses include large data platform business by SQL to NoSQL migration is more complex and application personnel learning cost is quite high, can't support affairs and multidimensional index, eventually making many business can't enjoy from NoSQL system linear development ability. Google internal MegaStore system complements Bigtable,it supports SQL, transactions, indexing, cross-cluster replication in the upper layer of the Bigtable, and became famous applications's storage engine, such as Gmail, APPEngine, and the Android Market. Therefore, we decided to explore providing cross-row transactions, indexes, SQL function without sacrificing the linear expansion of capacity in the upper layer of the HBase by theoretical model MegaStore. The system provides simple user interface: SQL, the user can do not need to pay attention to the hbase schema design, greatly simplifies the user's data migration and learning costs. To see what's supported, go to our language reference guide, and read more on our wiki. Become a standard distributed relational database,which's storage engine is nosql system, for example the hbase.

QUESTION
building this lightbox in React, the problem I am facing is that when I goto the next image in the array, it's empty and just showing "Object object" as the error. I am grabbing both the image and text from the array of objects. Anyone have any ideas? The showNext() function is where it's not working. Thanks
...ANSWER
Answered 2022-Jan-08 at 16:51Inconsistent types of imageToShow local state seems to be at fault (cannot test this without the actual repo). Typescript is great at catching this early.
imageToShow state has this type: { image: .jpeg, text: string }.
In imageCards callback on the img you pass { image: .jpeg } into showImage function, which then uses setImageToShow to set the image to show. Instead, you should be passing the correct state shape i.e. { image, text }.
Also, in your jsx, you need to access the image component in img tag like so:
If you look at your setImageToShow calls in showNext and showPrev, the nextImage variable is the entire image object e.g. { image: Bee, text: "Bee" }, since you access images_arr at a specific index (btw, keep you naming consistent to camelCase).

QUESTION
I'm building a lightbox in React that loops over an array of objects but I can't seem to get both the image and text to display. Ultimately I want each image to have text over it just identifying each pest.

QUESTION
I have created a wallet using bitcoinlib. The wallet is named 'my-awesome-wallet55.' When I try to open my existing wallet with a newly generated mnemonic phrase, the behavior I expect is an exception or security error, however the wallet opens anyway. I can manually check the private keys to create my own security check, but shouldn't trying to open an existing wallet with the wrong key fail? Seems like a pretty big security issue otherwise.

QUESTION
I have a TreeViewItem with custom Style, which I want to have a behavior like the following, so I want to set it as a side menu in my WPF application. The problem is that I want to keep only one TreeViewItem as expanded, while the others are collapsed, as long as they are not ancestors of the selected one. For example if I select, Cat, within Mammal, Mammal should obviously be expanded as well, but not Insects. If I select Africa, Africa and Continents must be expanded, while America, Europe and Asia must be collapsed. Also something strange happens, the SelectedItemChanged event is not firing, so the IsSelected property is not changing when selecting a new TreeViewItem, so I leave the style that I apply to the TreeViewItem.
Custom Styles
