gps - What kind of NoSQL storage should we use? -

-

We are an IOT company providing services for transportation and logistics companies. As a basic service provider, we offer GPS tracking devices to our customer.

However the format of GPS tracking data is quite clear (GPSID, longitude, latitude, speed, direction, report time, etc.), but it is huge. Each device reports GPS tracking information per 10 seconds, and we have 100k devices, thus 60 * 60 * 24 * 100000/10 = 864 M lines of new data generated each day

Using data collected by GPS tracking, the equipment of a particular vehicle, the client has a fixed time period (for example, in the last 10 days, 60 * 60 * 24 * 10/10 = 86.4K of data Rows) will review this vehicle's mark within.

We currently use MySQL as a storage medium, and take advantage of its prickly and table split (based on GPSID). But since the data is so large and inquiries about this happen so often, I wonder if we can use a NoSQL storage to better fit this scenario?

Historical data is also useful for data analysis.

Appreciate.

It seems as if you want a time series database, from time to time, for large arrays of numbers indexed There are customized databases. Wikipedia lists many open source and proprietary databases for the time series, in which several cassendras have been created at the top.

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
