chana | Avro Data Store based on Akka

This is what I meant by iterating over the length of the lists, I have added a code from where you can get an idea of how you can parse.

UPDATED CODE

Ok, I believe that I've figured it out. It looks like Go allocates eagerly and the discrepancy is just due to the way the Go memory profiler takes samples.

Go allocates channel memory eagerly

The docs for make promise that

The channel's buffer is initialized with the specified buffer capacity.

I looked into the code for makechan, which gets called during make(chan chantype, size). It always calls mallocgc directly - no laziness.

Looking into the code for mallocgc, we can confirm that there's no laziness within mallocgc (besides the doc comment not mentioning laziness, mallocgc calls c.alloc directly).

pprof samples at the heap allocation level, not the calling function level

While looking around mallocgc, I found the profiling code. Within each mallocgc call, Go will check to see if its sampling condition is met. If so, it calls mProf_Malloc to add a record to the heap profile. I couldn't confirm that this is the profile used by pprof, but comments in that file suggest that it is.

The sampling condition is based on the number of bytes allocated since the previous sample was taken (it draws from an exponential distribution to sample, on average, after every runtime.MemProfileRate bytes are allocated).

The important part here is that each call to mallocgc has some probability of being sampled, rather than each call to foo. This means that if a call to foo makes multiple calls to mallocgc, we expect that only some of the mallocgc calls will be sampled.

Putting it all together

Every time my function foo is run, it will eagerly allocate memory for the 4 channels. At each memory allocation call, there is a chance that the Go will record a heap profile. On average, Go will record a heap profile every 512kB (the default value of runtime.MemProfileRate). Since the total size of these channels is 488kB, on average we expect only one allocation to be recorded each time foo is called. The profile I shared above was taken relatively soon after the service restarted, so the difference in number of allocated bytes is the result of pure statistical variance. After letting the service run for a day, the profile settled down to show that the number of bytes allocated by lines 142 and 146 were equal.

It's very easy to tell.

You can achieve this by combination of Divs and tables.

As mentioned in the comment, if you want to ensure balance, you can just forgo using select altogether in the reading goroutine and rely on the synchronisation provided by unbuffered channels:

I'd personally start the whole thing again, but adding this to your CSS should help

In the example code, they have used images with the same width and height, so there won't be any design breaks. But in your case, you have used images with dimensions that make those design breaks.

Can you try this code and check whether this solves your issue.

Define the types you'd like to deserialise into, for example:

In this case I recommend to decode the JSON as dictionaries [String:[String]]
