[2pt] Add comparison table of Go connectors

[DifferentialOrange]

Compare features of our own tarantool/go-tarantool connector with two open-source connectors: viciious/go-tarantool and FZambia/tarantool.

[DifferentialOrange]

Btw, I'm lucky that there are only three connectors and there are no issues with 5th column like in Python comparison table.

[DifferentialOrange]

Also in last force-push I removed "eval supported" in SQL as discussed

[DifferentialOrange]

Added links to tarantool/go-tarantool#48, tarantool/go-tarantool#118, tarantool/go-tarantool#124

[DifferentialOrange]

So, @Totktonada , is this PR LGTM to send to Doc team for a review?

[DifferentialOrange]

I'm ok, @Totktonada ?

[Totktonada]

LGTM.

I left several optional comments.

[DifferentialOrange]

So it seems like after last commit we don't have any objections and it's ready to merge

[art-dr]

I'll merge this PR and then create a new one where I'll move the table to the "Connectors" chapter, as we've already done with Python connectors (https://www.tarantool.io/en/doc/latest/book/connectors/). It is the safest way not to lose Crowdin translations.

[viciious]

What's batching in that comparison table btw?

[Totktonada]

When we provide an API to collect several requests (usually DML) into a batch and send them at once. It may be necessary for a synchronous connector and has not much sense for an asynchronous one.

We removed it from this table, because all those connectors are asynchronous.

[viciious]

OK, thanks!

One feature of viciious/go-tarantool that may come handy for some people is that is also provides instrumentation for reading snapshot and xlog files via snapio module: https://github.com/viciious/go-tarantool/tree/master/snapio

Not sure whether you want it in the comparison table or not but I thought it was worth mentioning anyway

[Totktonada]

Nice! I filed #2637 to don't forget about it.

[viciious]

Oh and it also supports connecting to Tarantool instance as a replication slave and also implements unpacking of query structs should you want to implement your own Iproto proxy. Guess that's worth adding to comparison table as well.

[Totktonada]

supports connecting to Tarantool instance as a replication slave

It is in the table (written as 'Can mimic a Tarantool instance (also as replica)').

implements unpacking of query structs should you want to implement your own Iproto proxy

Looks worthful to mention, thanks!

Aren't you mind to open a pull request aginst the doc/book/connectors/__go.rst file in this repository? So you can give your wording for your connector.

@viciious If you do open a PR as @Totktonada suggested above, please mention or assign me and @arctic-dreamer. Thanks!

[Totktonada]

Filed #2645 to don't miss it.
