imho, great job, there are of course questions as to how quickly you did it.... if this is within the space of an hour.... well that's kind of over the top!
checked the revised version - ok, everything works correctly
This tweak? Right from the start, about 30 minutes in total.
This craft? From the beginning, a grand total of 30 minutes.
I won't flatter.
thanks again!
ZS: what's that for? one of the uses - in this codehttps://www.mql5.com/ru/forum/325418/page4#comment_16116740
you can load/save several objects through a file and also you can add the object generated by the tester to the runtime via input string without stopping EA execution, I already did it through binary exchange, but json is good - you can read it without additional manipulation

Just for internal use - it's easier to binary data, IMHO. JSON, though, is more for data exchange over the network, there, on the receiving / transmitting time, time for serialization / deserialization, doesn't mean anything. And so, if you need to organize an exchange on one machine, then, IMHO, File mapping is the best, and fast and easy, and on the network - there web soccet will rule.

No, the data exchange is already done and working - binary data through the database Redis - exchange speed microseconds - the volume of exchange ... well, seems not limited to test 600 mb with no problems, and synchronization is provided, through template all wrappers, write read in one command - in general, without much effort, everything runs smoothly and reliably
json to read/store in a file - one time operation and as I wrote to get a chance to do something in time
the task is roughly formulated like thishttps://www.mql5.com/ru/forum/85652/page50#comment_16415557 , in general I move as described )))

What version of Redis ?
I'm just looking forward to Streams 5 feature, otherwise redis is not so interesting... And where can i get 5 for windows ?
Redis what version ?
I have a local under Windows, purely for memory sharing
Redis 3.2.100 64 bit
didn't really think it through, wrapped in ServiceStack.Redis dll from githab, not knowing the material - a couple of days' work
And where can I get 5 for Windows?
It's not available. The Windows project was abandoned long ago.
but there is a lot of information on the net how to run linux software on vin 10https://redislabs.com/blog/redis-on-windows-10/
What's the problem, allocate 12 bytes of memory on the stack, don't know for sure what a string object is?
What a bummer!
1 - by creating an object. 2 - just through a normal function call. The first number is time in milliseconds, don't pay attention to the second one.
It is almost 10 times faster (and sometimes more than 10 times faster). What a sad thing... stack... pile... ***cha

Consider it like in C# - the object is always in the heap. Only scalars, descriptors and (as an exception) some arrays of known size are on the stack.

You forgot about structures and classes (without new) - they are both allocated on the stack.

Can you explain what this is all about, because I'm a bit dumb, I've read it three times and still don't get it...
