You could try running a

command from onPause().
At the very least, that would dramatically reduce the amount of work
that H2 has to do during recovery.

At first I will save h2 spatial index in the following way
CALL CreateSpatialIndex(...);
I would like to save my h2spatial index on the same area where h2 save its

from outside of h2 ?
Thanks for support

Hello,
I understand that H2 syntactically supports the UNSIGNED keyword in DDL to
stay compatible with MySQL:
CREATE TABLE t_unsigned (
u_byte tinyint unsigned,
u_short smallint unsigned,
u_int int unsigned,
u_long bigint unsigned
);
Obviously, this is just a
I can't see that adding full support is likely, since UNSIGNED datatypes
are hardly a SQL standard.
After all, the primary purpose of supporting them is to make running
unit tests for people who are MySQL easier, so it's not like it's a
production situation.
But I can see that making them

One day I tried to connect to H2 and got this error via the browser tool:

Hi,
The error message Caused by: java.lang.NoClassDefFoundError:
org/h2/engine/Constants doesn't say much about the state of the database

Hi,
Yes, your are right! It's weird that two distinct error codes are in the
stack trace (I have never seen that before).
But anyway, it seems like both version 1.3.171 and 1.3.169 are in the
classpath.

Hi,
When I get the map with store.openMap(name map) I see that all the
objects are built, auto vivification, like in Perl.
Opening the map will not read all entries of the map from disk. It might
read a few entries (the root page of the b-tree), but that's about it. Even
if you call map.get()
