I have a MariaDB 10.2.13 server. This server contains a database called 'factory'. This database contains a table called 'client'. This is a large table.
client table structure:
CREATE TABLE `client` (
`id` varchar(250) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
`name` varchar(250) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
`lastname` longtext DEFAULT NULL,
`age` int(11) NOT NULL,
`address1` varchar(250) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
`time` bigint(20) NOT NULL,
`comment` longtext NOT NULL,
`address2` varchar(250) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
PRIMARY KEY (`id`),
KEY `product_idx1` (`address1`),
KEY `product_idx3` (`address2`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 ROW_FORMAT=COMPRESSED KEY_BLOCK_SIZE=4
I wanted to export the table by the mysqldump instruction as follows:
mysqldump factory --quick --complete-insert --no-create-db --no-create-info --skip-extended-insert --compact --tables client --max_allowed_packet="3G" > dump_client.sql
Then I got the error message as follows:
mysqldump: Error 2013: Lost connection to MySQL server during query when dumping table `client` at row: 1002046
I was trying to check the record by the SELECT Statement as follows:
SELECT * from client limit 1002046,1'
Even though, I didn't see anything irregular in data. I think it is happening when ROW_FORMAT is COMPRESSED. I can't change the ROW_FORMAT because it's a requeriment.
What can I do for this case?
