Beispiel #1

void StorageSetOrJoinBase::restoreFromFile(const String & file_path)
{
    ReadBufferFromFile backup_buf(file_path);
    CompressedReadBuffer compressed_backup_buf(backup_buf);
    NativeBlockInputStream backup_stream(compressed_backup_buf, 0);

    backup_stream.readPrefix();
    while (Block block = backup_stream.read())
        insertBlock(block);
    backup_stream.readSuffix();

    /// TODO Add speed, compressed bytes, data volume in memory, compression ratio ... Generalize all statistics logging in project.

        << backup_stream.getProfileInfo().bytes / 1048576.0 << " MiB. "
