Developers of hypersonic promise increase of performance?
But I'm afraid problems with administrating and other aspects of using hsqlDB.
Are anybody using this in production? Is it good idea?
回答1:
Many companies are using HSQL in production.
Among those not on the list, a certain well-known (though not necessarily well liked) company that makes an antivirus product (whose name rhymes with "Horton") is using HSQL-based software for their update server management. I know because I wrote it :-)
I'm not sure what "problems with administrating" you're referring to. They have both command-line and (somewhat simplistic) GUI clients plus pretty much everything is doable over JDBC so
you can take your pick from lots of tools / IDE plugins.
That said, whether using it is a good idea for you depends on your requirements. It's certainly not a drop-in replacement for Oracle (Postgres / DB2 / MySQL / what have you). But it most definitely has its uses.

You may wish to look at H2, which is a more full featured DB, while still supporting most of the features of HSQLDB like memory only DBs.
