Description
$pathname
)Loads a chdb file, by mapping it into memory.
Note:
While some validity checks are performed on the specified file, they are mostly there to avoid the possibility of common mistakes (for example, loading a file which is not a chdb database, or that is somehow incompatible with the current system). A maliciously crafted chdb file can thus be dangerous if loaded, so chdb files should be trusted and treated with the same security protections used for PHP shared libraries.
Parameters
-
pathname -
The name of the file to load.
Errors/Exceptions
Throws an exception in case the chdb file hasn't been successfully loaded.
Note:
A valid chdb file might fail to load in case it was created on an architecture with a different endianness, with a different version of chdb, or if the file is too big to be mapped into memory (mostly in case of huge files and 32-bit architectures). In these cases the load will fail by throwing an exception, but otherwise not performing any illegal operation.
