Cannot start kuzu_shell with existing data (database path)

[uwegeercken]

I just built kuzu from src.

Compiling went well, but when I wanted to start kuzu_shell with the usual -i flag for the database path I get an error:

Flag could not be matched: 'i'
  ./kuzu_shell databasePath {OPTIONS}

    KuzuDB Shell

  OPTIONS:

      databasePath                      Database path.
      -h, --help                        Display this help menu
      -d, --defaultBPSize               Size of buffer pool for default and
                                        large page sizes in megabytes
      "--" can be used to terminate flag options and force all following
      arguments to be treated as positional options

Note that the database path already contains data from the kuzu 0.2 version!

Running kuzu_shell without the -i also does not work (with an existing db pat)::

./kuzu_shell /home/uwe/development/kuzu-db
Opened the database at path: /home/uwe/development/kuzu-db
Enter ":help" for usage hints.
std::bad_alloc

The client immediately exits.

But running kuzu_shell on an empty directory works:

./kuzu_shell /home/uwe/development/kuzu-db2
Opened the database at path: /home/uwe/development/kuzu-db2
Enter ":help" for usage hints.

Hi @uwegeercken,

This is desired behaviour. Because we are iterating quickly and constantly modifying storage format. We cannot provide backward compatibility between different versions. This will be the case for a while until we stabilize on the storage side.

Yes, I thought so. I wanted to add it here so that others see the issue as well.

Thanks,

Uwe

PR #1436 has introduced storage format number so we throw error message if storage version is not aligned with kuzu binary version.
