The code annotation (about 'enable_http_compression') is wrong.

[ghost]

The default value of option 'enable_http_compression' is not false

    /** Compress the result if the client over HTTP said that it understands data compressed by gzip or deflate. (default: false) */
    enable_http_compression?: Bool;

Unlike the option default value specified as false when creating a client that inquires DB with a Readonly user,
The error below is exposed.
Cannot modify 'enable_http_compression' setting in readonly mode.

REF:

clickhouse-js/src/settings.ts

Line 317 in 97a6162

/** Compress the result if the client over HTTP said that it understands data compressed by gzip or deflate. (default: false) */

Thanks for pointing it out.

That one we parsed from the server-side C++ code of ClickHouse itself (for example this), so the default value mention is coming from those comment sections.

The reason why we added these additional typings is that you could provide these settings on a query basis (for example), so it is better to have some types there for development experience in the IDE.

I guess we should remove any mention of default there, as the client actually has it true for requests by default.
