The docs express that exit({aborted, Reason}) are called when
an error occur.

* dgud/mnesia/try-catch:
mnesia: Replace catch with try-catch
|
|
Avoids building stacktraces where it is not needed and do
not mask errors, i.e. only catch the relevant classes in each try.

match_object returned wrong objects when matching on non key fields
and updates in the same transaction had been performed.

For performance reasons the file data is not synced to disk in mnesia,
data loss can happen between each dump.
mnesia:dump_log() can be used explicitly to ensure data is written to disk.
But that can take a long time, so mnesia:sync_log() which just
sync the log have been added.

Since the table loader also sets (table) write locks, a special
lock type, 'load', was needed. Unfortunately, this affects mnesia
activity callbacks that redefine the lock operation.

* is/mnesia-send-compressed:
Add option to compress data when copying tables between Mnesia nodes
OTP-8406 Igor Ribeiro Sucupira added the option to compress data when
copying tables between Mnesia nodes.
|
|
Optionally using data compression for copying Mnesia tables allows
the system to be tuned to eliminate network bottlenecks from
deployments where enough CPU is available to use zlib.
With this patch, running erl -mnesia send_compressed <level>
will enable compression for sending tables between nodes. The
compression level can be any integer in [0, 9], with 0 (the
default) meaning no compression (exactly the previous behaviour)
and 9 being the highest compression level.
To set any non-zero compression level at the sender, both nodes
must have the updated Mnesia modules (the receiver will work
according to the sender's configuration).
