A
java library to manage java data
object persistence in file system transparently without using
database, do not need
to manage the field-by-field storage and retrieval to and from
the
file.
- easy to use
- guarantees all ACID properties
- object oriented, write your model, store it. Do not need
query language, juste navigate in your model.
- multi data access session (
multi-Thread, transactional data store )
- save all objects
of object graph starting from a root object to file system, one
heap file record by object instance
- lazy loading of object:
- make
able to not waste memory with large
object graph when only need to access to some of them.
- manage more object than
memory can contains
- manage enum state persistence
- crash safe, may accept JVM
stop at any time even if write in file
( only the last commit is lost)
- file corruption detection
- garbage collector for file
data record that will never be accessed
- The object that can
be persited are POJO that not needs to
implement Serializable, but there is some conditions
- Possibility to store serialization of instance of
class in
one data record. can be comprerssed or not
