Add support for gzip compression of query response

[bednar]

The clients should support compress queries after enable gzip: influxDBClient.enableGzip();

influxdata/influxdb#14495

👋 Hi folks, I not quite sure that really works from a query executed by kotlin-client.
Indeed, the facts that we set application/json by default for all query() calls that blocks the BridgeInterceptor to do his job to add the Accept-Encoding: gzip header (quick look here 👀).
IMO the Accept-Encoding: application/json is not used by the InfluxDB server because it always sent you back application/csv data (for and InfluxDB 2.0 server with Flux request).

👉 So I have a commit ready to PR if you want, to fix this issue.

💬 Let me know what do you think, and if you want me to create it.

Hi @antoinedvd,

thanks for your comment. The default value for Accept-Encoding should be identity. The GZIP compression is managed by GzipInterceptor.java.

You could enable GZIP compression by:

var influxDBClient = influxDBClient.enableGzip()

https://github.com/influxdata/influxdb-client-java/blob/master/client-kotlin/src/main/kotlin/com/influxdb/client/kotlin/InfluxDBClientKotlin.kt#L71

Could you prepare a PR with Accept-Encoding: identity?

Hi @bednar,

Thank you for your answerd.

Of course I tried to use the var influxDBClient = influxDBClient.enableGzip() but that didn't works well.
If you look here :

influxdb-client-java/client/src/main/java/com/influxdb/client/internal/GzipInterceptor.java

Line 79 in c6aaa57

// The okhttp3.internal.http.BridgeInterceptor add gzip accept

Its clearly wrote that gzip header is added by Bridge interceptor.
So if I add Accept-Encoding: identity the same issue will be produced. Don't you think ?

You are right, sorry for wrong direction ... feel free to create PR

@bednar no pb 😉
I will create the PR.
Thank you for your reactivity ! 👍🏻
