PyDbLite is a small, fast, pure-Python, in-memory database management
program
The database object supports the iterator protocol, so that requests
can be expressed with list comprehensions or generator expressions
instead of SQL. The equivalent of :
cursor.execute("SELECT name FROM table WHERE age=30")
rows = cursor.fetchall()
is :
rows = [ row["name"] for row in table if row["age"] == 30 ]
Data is stored on disk in a single cPickled file. Records are indexed
by a unique record identifier, that can be used for direct access.
Since operations are processed in memory they are extremely fast,
nearly as fast as SQLite in the few tests I made. An index can be
created on a field to speed up selections
