This page briefly explains some additional features and concepts of the python
library which may be useful.

## Exceptions

In case of erroneous transactions, connection problems or other problems, PyLinkAhead may raise
exceptions. Some of these errors are representations of errors encountered in the LinkAhead server,
others stem from problems on the client side.

Exceptions are ordered hierarchically from general exceptions to specific transaction or connection
problems. The base exception class for LinkAhead errors is `LinkAheadException`. For more
information on specific error types, see
the [code documentation](/reference/pylib/api/linkahead.exceptions.rst).
