Default opts for BETA database, MVStore.
legacy-defaultsclj
Default opts for legacy database, PageStore: no MV_STORE, no MVCC.

legacy-specclj
(legacy-spec path)(legacy-spec path opts)Like spec, but merges legacy-defaults to disable BETA features.
Like spec, but merges legacy-defaults to disable BETA features.
specclj
(spec path)(spec path opts)Create H2 connection spec for given path String (only required argument).
Store depends on method parameter of opts:
- :raw sets :subname to given path verbose (best of luck!)
- :tcp uses server, port and path for :subname
- :mem sets database to in-memory storage, JVM runtime persistent
- :nio-mem-fs is the new in-memory storage, JVM runtime persistent
- :nio-mem-lzf for new in-memory compressing storage, JVM runtime persistent
- :raf sets database to embedded, RandomAccessFile local storage
- :async uses AsyncChannel instead of RandomAccessFile, may be faster
- :nio uses Java nio instead of RandomAccessFile, may be faster
- :nio-mapped uses nio over mem-mapped file, 2GB max size (split implied)
- :default or anything else means local embedded (nio) file storage.
Other opts are :user, :password, :server & :port. Self explanatory.
For split filesystem use :split? flag and (2 ** :part) bytes for size. This mode can be stacked with some filesystem modes.
For :nio-mem-lzf the :part argument is used as percentage of blocks that should be kept uncompressed, so ideally it's between 1 and 99.
:flags should be a map of {String String}, like {COMPRESS TRUE}, it will overwrite all flags set by default so YMMV.
All in-memory stores are opened with DB_CLOSE_DELAY=-1, which means they will be available until JVM shuts down. You can close them with SHUTDOWN command.
