How to optimize MySQL for faster inserts?
Some optimizations don’t need any special tools, because the time difference will be significant. For example, when we switched between using single inserts to multiple inserts during data import, it took one task a few hours, and the other task didn’t complete within 24 hours.
Why does insert to table slow down MySQL?
Inserting to a table that has an index will degrade performance because MySQL has to calculate the index on every insert. In case there are multiple indexes, they will impact insert performance even more. Check every index if it’s needed, and try to use as few as possible.
Which is faster one INSERT statement or multiple inserts?
MYSQL 5.5 One sql insert statement took ~300 to ~450ms. while the below stats is for inline multiple insert statments. I just did a small benchmark and it appears that for a lot of line it’s not faster.
Why does MySQL support 50, 000 concurrent inserts per second?
The reason for that is that MySQL comes pre-configured to support web servers on VPS or modest servers. The assumption is that the users aren’t tech-savvy, and if you need 50,000 concurrent inserts per second, you will know how to configure the MySQL server.
How many inserts per query does MySQL do?
It takes around 1,000 inserts per query to reach the maximum throughput in both cases, but 40 inserts per query are enough to achieve 90% of this throughput on localhost, which could be a good tradeoff here. It’s also important to note that after a peak, the performance actually decreases as you throw in more inserts per query.
How to do an extended insert in MySQL?
Extended inserts. A typical SQL INSERTstatement looks like: INSERT INTO user (id, name) VALUES (1, ‘Ben’); An extended INSERTgroups several records into a single query: INSERT INTO user (id, name) VALUES (1, ‘Ben’), (2, ‘Bob’); The key here is to find the optimal number of inserts per query to send.
