And this is the tricky bit. Edorian was on the right way with his proposal, I will do some more Benchmark and I'm sure we can reach on a 2x Quad Core Server 50K Inserts/sec. The benchmark is sysbench-mariadb (sysbench trunk with a fix for a more scalable random number generator) OLTP simplified to do 1000 point selects per transaction. This limits insert speed to something like 100 rows per second (on HDD disks). Is there any fixed limit on how many inserts you can do in a database per second? HamsterDB, SQLite, MongoDB ...? This tells me nothing about whether these were concurrent inserts, if bulk operations were used, or what the state of the caches were. 1 minute. The default MySQL setting AUTOCOMMIT=1 can impose performance limitations on a busy database server. Use something like mysql but specify that the tables use the MEMORY storage engine, and then set up a slave server to replicate the memory tables to an un-indexed myisam table. with 100 concurrent connections on 10 tables (just some values). If it's for legal purposes: a text file on a CD/DVD will still be readable in 10 years (provided the disk itself isn't damaged) as well, are you sure your database dumps will be? In PostgreSQL everything is transaction safe, so you're 100% sure the data is on disk and is available. We have the same number of vCPUs and memory. I have also made changes to the MySQL server to optimise for large tables and bulk inserts etc. Understand the tradeoff. What you're missing is that multiple users can enqueue changes in each log flush. edit: You wrote that you want to have it in a database, and then i would also consider security issues with havening the data on line, what happens when your service gets compromised, do you want your attackers to be able to alter the history of what have been said? Another thing to consider is how to scale the service so that you can add more servers without having to coordinate the logs of each server and consolidate them manually. We know that fsync (2) takes 1 ms from earlier, which means we would naively expect that MySQL would be able to perform in the neighbourhood of: 1s … But no 24 hour period ever passes without a crash. What you might want to consider is the scaling issues, what happens when it's to slow to write the data to a flat file, will you invest in faster disk's, or something else. First and the foremost, instead of hardcoded scripts, now we have t… Assume your log disk has 10ms write latency and 100mB/s max write throughput (conservative numbers for a single spinning disk). Any proposals for a higher performance solution? It's surprising how many terrible answers there are on the internet. We have reproduced the problem with a simpler table on many different servers and MySQL versions (4.X). If you will ever need to do anything with data, you can use projections or do the transformations based on streams to populate any other datastore you wish. Read requests aren't the problem.

This value of 512 * 80000 is taken directly from the Javascript code, I'd normally inject it for the benchmark but didn't due to a lack of time. Stack Overflow for Teams is a private, secure spot for you and A complete in memory database, with amazing speed. There is no siginifcant overhead in Load Data. How much time do you want to spend optimizing for it, considering you might not even know the exact request? @Frank Heikens - The data is from a IM of a dating site, there is no need to store it transaction safe. Soon after, Alexey Kopytov took over its development. It's up to you. This is a reason more for a DB System, most of them will help to be able to scale them without troubles. So i have to agree with the above statement. PeterZaitsev 34 days ago. If each transaction requires 100kB of log space (big), you can flush 1000 transactions per second on the disk, so long as you have at least 10 users waiting to commit a transaction at any time.

You mention the NoSQL solutions, but these can't promise the data is realy stored on disk. Example: iiBench (INSERT Benchmark) •Main claim : • InnoDB is xN times slower vs Write-oriented Engine XXX • so, use XXX, as it’s better •Test Scenario : • x16 parallel iiBench processes running together during 1H • each process is using its own table • one test with SELECTs, another without.. •Key point : • during INSERT activity, B-Tree index in InnoDB growing quickly If MySQL was batching fsyncs, we’d expect something far lower. In my no-so-recent tests, I achieved 14K tps with MySQL/Innodb on the quad-core server and throughput was cpu-bound in python, not mysql.

Case 2: You need some event, but you did not plan ahead with the optimal INDEX. This problem is almost ENTIRELY dependent on I/O bandwidth. You could even point to SO for what's considered reasonable. Write caching helps, but only for bursts. There are Open Source solutions for logging that are free or low cost, but at your performance level writing the data to a flat-file, probably in a comma-delimited format, is the best option.

And this is the tricky bit. Edorian was on the right way with his proposal, I will do some more Benchmark and I'm sure we can reach on a 2x Quad Core Server 50K Inserts/sec. The benchmark is sysbench-mariadb (sysbench trunk with a fix for a more scalable random number generator) OLTP simplified to do 1000 point selects per transaction. This limits insert speed to something like 100 rows per second (on HDD disks). Is there any fixed limit on how many inserts you can do in a database per second? HamsterDB, SQLite, MongoDB ...? This tells me nothing about whether these were concurrent inserts, if bulk operations were used, or what the state of the caches were. 1 minute. The default MySQL setting AUTOCOMMIT=1 can impose performance limitations on a busy database server. Use something like mysql but specify that the tables use the MEMORY storage engine, and then set up a slave server to replicate the memory tables to an un-indexed myisam table. with 100 concurrent connections on 10 tables (just some values). If it's for legal purposes: a text file on a CD/DVD will still be readable in 10 years (provided the disk itself isn't damaged) as well, are you sure your database dumps will be? In PostgreSQL everything is transaction safe, so you're 100% sure the data is on disk and is available. We have the same number of vCPUs and memory. I have also made changes to the MySQL server to optimise for large tables and bulk inserts etc. Understand the tradeoff. What you're missing is that multiple users can enqueue changes in each log flush. edit: You wrote that you want to have it in a database, and then i would also consider security issues with havening the data on line, what happens when your service gets compromised, do you want your attackers to be able to alter the history of what have been said? Another thing to consider is how to scale the service so that you can add more servers without having to coordinate the logs of each server and consolidate them manually. We know that fsync (2) takes 1 ms from earlier, which means we would naively expect that MySQL would be able to perform in the neighbourhood of: 1s … But no 24 hour period ever passes without a crash. What you might want to consider is the scaling issues, what happens when it's to slow to write the data to a flat file, will you invest in faster disk's, or something else.
