Review Comment:
   `alt_rec` returns `get_main_rec` instead of `get_alt_rec`, so tests that 
rely on an alternate record (e.g. replace / upsert paths) end up using the main 
record and lose coverage (and can mask bugs).
   ```suggestion
           return get_tuple(tab_info.all_column_names, 
tab_info.get_alt_rec(key));
   ```

Review Comment:
   `uuid::from_string` uses `std::string`, but this header doesn't include 
`<string>`. Relying on indirect includes can break compilation depending on 
standard library / build flags; include `<string>` directly here to make the

Review Comment:
   Log message concatenation is missing spaces and reads awkwardly ("... for 
table<name>error ..."). This makes logs harder to scan and grep; include 
separators and consider standardizing the wording.
   ```suggestion
               self->m_connection->get_logger()->log_error(
                   "Error while updating partition assignment for table '" +

Review Comment:
   Method name `drop_table_if_exits` is misspelled ("exits" vs "exists"), which 
makes the test fixture harder to read/search. Consider renaming to 
`drop_table_if_exists` (and update call sites).
   ```suggestion
       void drop_table_if_exists() {
   ```

Review Comment:
   Log message grammar: "random node will called" is ungrammatical and also 
missing a word ("be"). Fixing this improves log clarity when partition 
assignment isn't available.
   ```suggestion
           m_connection->get_logger()->log_debug("No partition distribution 
available, a random node will be called");
   ```
