[issue13299] namedtuple row factory for sqlite3

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

There is significant overhead. Microbenchmark results:

$ ./python -m timeit -s "import sqlite3; con = sqlite3.connect(':memory:')"  "con.execute('select 1 as a, 2 as b').fetchall()"
10000 loops, best of 3: 35.8 usec per loop

$ ./python -m timeit -s "import sqlite3; con = sqlite3.connect(':memory:'); con.row_factory = sqlite3.Row"  "con.execute('select 1 as a, 2 as b').fetchall()"
10000 loops, best of 3: 37.3 usec per loop

$ ./python -m timeit -s "import sqlite3; con = sqlite3.connect(':memory:'); con.row_factory = sqlite3.NamedTupleRow"  "con.execute('select 1 as a, 2 as b').fetchall()"
10000 loops, best of 3: 92.1 usec per loop

It would be easier to add __getattr__ to sqlite3.Row.
