public final class QueryInfo extends com.google.protobuf.GeneratedMessageV3 implements QueryInfoOrBuilder
 Information about a query which a client sends to a ClickHouse server.
 The first QueryInfo can set any of the following fields. Extra QueryInfos only add extra data.
 In extra QueryInfos only `input_data`, `external_tables`, `next_query_info` and `cancel` fields can be set.
Protobuf type clickhouse.grpc.QueryInfo

 The compression level should be in the following range (the higher the number, the better the compression):
 none: compression level isn't used
 gzip: 0..9; 0 means no compression, 6 is recommended by default (compression level -1 also means 6)
 brotli: 0..11
 lzma: 0..9; 6 is recommended by default
 zstd: 1..22; 3 is recommended by default (compression level 0 also means 3)
 lz4: 0..16; values < 0 mean fast acceleration
 bz2: 1..9

    • getTransportCompressionType

      public String getTransportCompressionType()
       Transport compression is an alternative way to make the server to compress its response.
 This kind of compression implies that instead of compressing just `output` the server will compress whole packed messages of the `Result` type,
 and then gRPC implementation on client side will decompress those messages so client code won't be bothered with decompression.
 Here is a big difference between the transport compression and the compression enabled by setting `output_compression_type` because
 in case of the transport compression the client code receives already decompressed data in `output`.
 If the transport compression is not set here it can still be enabled by the server configuration.
 Supported compression types: none, deflate, gzip, stream_gzip
 Supported compression levels: 0..3
 WARNING: Don't set `transport_compression` and `output_compression` at the same time because it will make the server to compress its output twice!
      string transport_compression_type = 22;
      Specified by:
      getTransportCompressionType in interface QueryInfoOrBuilder
      Returns:
