MySQL - Percona Edition.

Full table scan is taking over 1 second and crashing our backend servers, the table has about 1.2 million records, if the IP is located then it returns very quickly and has no issues, eventually we hit max connections on the server if it can't find it as it does a full table scan. This server is beefy, 128GB of ram + 800GB SSD and dual hexacore processors

SELECT *
  FROM geoip_proxy_ipv4_09_2018
  WHERE INET_ATON('192.168.0.1') BETWEEN ip_from AND ip_to
  LIMIT 1

The table structure is this:

If we do 800 requests per second (lookups) our database server and our backend servers max out their connections waiting for response from backend server... thoughts?

Need to make our MySQL queries faster on a large table (1544980 total records)

SELECT id,sender,recipient,message,priority,flash_message
FROM movistar_mt3_saca_nic
WHERE process=0
ORDER BY priority DESC, id ASC
LIMIT 10

Open in new window


its a transactional table, we select 10 numbers and try to bill them within 1 second for services and then they get updated with the bill status so they dont get billed twice...
a timer then selects another set of 10 numbers... the query is taking 3.5seconds...

the structure of the table is this:

CREATE TABLE IF NOT EXISTS `movistar_mt3_saca_nic` (
  `id` bigint(14) NOT NULL AUTO_INCREMENT,
  `batch_id` varchar(20) NOT NULL,
  `sender` varchar(50) NOT NULL,
  `recipient` varchar(50) NOT NULL,
  `message` varchar(180) NOT NULL,
  `sequence_number` int(11) NOT NULL DEFAULT '0',
  `command_status` varchar(11) DEFAULT NULL,
  `message_id` varchar(255) DEFAULT NULL,
  `done_date` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `service` bigint(14) DEFAULT NULL,
  `send_time` datetime(3) DEFAULT NULL,
  `confirm_time` datetime(3) DEFAULT NULL,
  `sequence_sending` int(11) NOT NULL DEFAULT '1',
  `process` int(11) NOT NULL DEFAULT '0',
  `priority` int(11) NOT NULL DEFAULT '0',
  `flash_message` int(11) NOT NULL DEFAULT '0',
  `transaction_id` varchar(50) DEFAULT NULL,
  `delivery_number` int(11) DEFAULT '1',
  `part_number` int(11) DEFAULT '1',
  `qty_attempts` int(11) DEFAULT '0',
  `product_id` varchar(50) DEFAULT NULL,

We have to serve 50,000,000,000 requests per day, our app can handle that, but we're not sure if our database skills are there to pick this up. We have a database server with 256gb of ram and 512GB SSD RAID using percona edition. Some of the data needs to stay on the database for 30 days, the transaction table where all requests are stored. what approach do we need to scale this horizontally? each endpoint requests runs about 4 queries...

Task availableI have found that this Dell PowerEdge T110 II that has two disks with Raid 1 configuration seems that one of the disk has failed. I have screen shots that I took from OpenManage Server Configuration for you to review. I believe that Disk 0:1 is the one has failed and I must first assigned it to be Global Hot spare and then re create the Raid1. Please review the attached file and advise if this is how I have to do it either from here or from Raid Bios.

MySQL Hot backup for 60GB database.

First I've read that mysql dump is can be slower than another enterprise app so that is where I'm exploring now.  
Trying to find a solution for a hot backup of a 60GB database.  It needs to be encrypted because of sensitive data so looking for the software to use, commands, and tips.

MySQL Enterprise Backup - Is what I'm looking at 30 day free trial but cannot find how much it cost?
If I wanted this recoverable up to the closet time like 15 minutes/1hour how can that be acomplished?  Which command?

I've also seen Percona XtraBackup 2.4.8 but seems to be Linux based and I would have to spin up and pay for another Linux server.  I know the db is small but the nightly backups we take would be bad if I could recover 23 hours ago.  I need a smaller window.  

Also since the DB is so small is it faster to backup to same server and then have an ftp script send or copy it somewhere else.
The fear is with this application it says there are reasons for a table to become corrupt.  So  I also won't know the time it does become corrupt is backing up every hour or every change just going to overwrite that?  How do I achoomplish the simple goal of Daister Recovery up to the minute of incident.  If it is a corrupt table or an entire database that needs to be restored for some reasons.
