Hi,
Your INSEERquery status is Copying to tmp table,
this means fetching rows which has to be inserted is slow.
You should tune SELECT statement in your insert query.
Adding indexes and/or simplifying query and/or .. so on.

Hi,
Your query have to access all rows in `myTable`, thus MySQL optimizer
guesses reading sequentially is faster than working through an
index.

The case of not using index,
* Reading whole myTable.MYD sequentially
* Sorting 443k rows

Hi,
Christophe has already told,
The used MySQL version is 5.5.40 from Debian Wheezy package.
Maybe you missed *mysql command-line client's --local-infile option*
$ bin/mysql
mysql SELECT @@version;

| 5.5.40-log |

Hello,
If you use any *NOT InnoDB* storage engine, you're right.
mysqldump with --single-transaction doesn't have any consistent as you say.
If you use InnoDB all databases and tables, your dumping process is
protected by transaction isolation level REPEATABLE-READ.
* storage engine, say MyISAM, will this dump be
of any useful?

Records: 0 Duplicates: 0 Warnings: 0
mysql56 EXPLAIN SELECT e.id FROM masik m STRAIGHT_JOIN egyik e ON e.id=
m.id WHERE e.duma= 'aaa' ORDER BY m.szam
Hello,
I can see MyISAM stores BLOB column as same space as other data type
column,
but InnoDB doesn't. (If you mean same .ibd file it's true)

ROW_FORMAT= Compact holds first 768 bytes of BLOB column,

Hello,
mysqladmin and mysql command-line client is included in MySQL-client
package.
mysql_secure_installation is included in MySQL-server but it's a perl
script which calls mysql command-line client internally.
Thus, you should install MySQL-client-*.rpm and try again.

Hello,
It's because of binlog_checksum = crc32 setted default at 5.6.5.

binlog_checksum = none on 5.6.

Because of that, those queries don't use index.
log-queries-not-using-indexes works even if query time less than
long-query-time.
