        Minimum number of http2 connection per port we want to keep. Based on initial perf test, number of HTTP/2 connection is not a significant performance factor. 2 is used by default, in case of one connection died.

@Default("25 * 1024 * 1024")
public final int http2MaxContentLength
        Maximum content length for a full HTTP/2 content. Used in HttpObjectAggregator. In HttpObjectAggregator, maxContentLength is not used to preallocate buffer, but it throws exception if content length great than maxContentLength TODO: Link this with blob chunk size.

@Default("1024 * 1024")
public final int nettyReceiveBufferSize
        The socket receive buffer size for netty http2 channel. If -1 is provided, code will not set socket buffer size explicitly. Linux kernel will do TCP buffer auto tune.

@Default("1024 * 1024")
public final int nettySendBufferSize
        The socket send buffer size for netty http2 channel. If -1 is provided, code will not set socket buffer size explicitly. Linux kernel will do TCP buffer auto tune.

        @Config("http2.drop.request.on.write.and.flush.timeout")
@Default("false")
public final boolean http2DropRequestOnWriteAndFlushTimeout
