Execution Time: Finding a File vs. Finding a Row in MySQL


Recommended Posts

What if I have 100,000 rows in a MySQL table, and a 100,000 files in a directory, each file representing a row in the MySQL table.... 


Which, in your experience, is faster to find? A file called 123456789.csv or a record where id='123456789'?


Any input is appreciated, thanks!

Table with over 180,000 records.

mysql> SELECT COUNT(*) FROM votes;
| COUNT(*) |
|   182685 |

Find 100,000th

mysql> SELECT * FROM test.votes
    -> WHERE id = 100000;
| id     | votes | type |
| 100000 |   647 |    7 |
1 row in set (0.00 sec)

Less than 1/100th of a second, so the question is "how long to find and read your file?"
