[go-nuts] Deallocate memory consumption of slice.

I have a sample go snippet which pulls 50k rows from source DB and inserts into target DB. https://go.dev/play/p/IVANZyVUbkm While doing so I create a empty slice and add operations to it. When the length of slice is > 10K, I do a bulk write to DB. The problem here is this script eats more me

Hello team, MongoDB Go bulk write takes up an slice of interfaces which is slice of operations. *https://go.dev/play/p/2vcHx5EFK5x * While doing so I create a empty slice and add operations to it. When the length of slice is > 10K, I do a bulk write to DB. The problem here is this script eats

[go-nuts] GO routine never exits based on stop condition - unable to find the reason

In this example, we have a *worker*. The idea here is simulate clean shutdown of all go routines based on a condition. In this case, go routines get spun - based on workers count. Each go routine reads the channel, does some work and sends output to the outputChannel. The main go routine rea

Re: [go-nuts] Speeding up multiple regexp matches

Thank you for excellent suggestions. I will explore and try them. I am wondering is it possible to single NFA/DFA from set of regular expressions (similar to aho-corasick which does for fixed strings) which can determine matched regexps with single pass on the input. Especially if regular expr

[go-nuts] Re: Speeding up multiple regexp matches

Is it possible to build an NFA/DFA from a list of regular expressions which can give the desired result i.e. list of regexps which matched the input string? Are there any existing libs for this? Do anybody konwof any existing algos for it, which I can use to implement it? -- You received this

[go-nuts] Re: Speeding up multiple regexp matches

- There are more than 10,000 regexps. - I need to do this task on ~ 800 million strings having max length 1KB each, and this number growing daily. - Currently regular expressions are simple. It's actually what MS SQL Server like operator supports. i.e. "_%[]^". See https:/

Not specific to golang. Incidentally I am using go to develop this particular tool. I have a piece of text that I want to test against a large number of regular expressions, where a different action is taken based on which regexps successfully matched. The naive approach is to loop through each
