![]() ![]() ROW_ID TEXT NOT NULL, // this is the primary key 324 column of these types : I want to create a table of 325 column: CREATE TABLE NAMESCHEMA. Parameters that I changed and works (after creating a new instance and initialized with the my.ini that is first modified with these settings): innodb_page_size = 64 kĪll the settings and descriptions in which I found the solution can be found here: ![]() The problem with this is that you have to create a new MySql instance, and migrate data to your new DataBase instance, from old one. innodb_log_buffer_size should be set to at least 16M (the default) when using 32k or 64k page sizes.įurthermore the innodb_buffer_pool_size should be increased from 128M to 512M at least, otherwise you will get an error on initialization of the instance (I do not have the exact error). For innodb_page_size=64k, extent size is 4MB. For innodb_page_size=32k, extent size is 2MB. ROW_FORMAT=COMPRESSED is not supported when innodb_page_size is set to 32KB or 64KB. Also if the ROW_FORMAT is set to COMPRESSED you cannot increase innodb_page_size to 32k, or 64K. If you increase the innodb_page_size, the innodb_log_buffer_size must be also increased. So if you do not change this value in my.ini before initialization, the default value will be 16K, which will have row size limit of ~8K. See Section 14.6.1, “InnoDB Startup Configuration”. If no value is specified, the instance is initialized using the default page size. Innodb_page_size can only be configured prior to initializing the MySQL instance and cannot be changed afterward. The trick is that this parameter can be only changed during the INITIALIZATION of the mysql service instance, so it does not have any affect if you change this parameter after the instance is already initialized (the very first run of the instance). For both 32k and 64k page sizes, the maximum row length is approximately 16000 bytes. Support for 32k and 64k page sizes was added in MySQL 5.7. In current row format, BLOB prefix of 0 bytes is stored inline.Īfter spending some hours reading the manual of MYSQL, found the solution! Changing some columns to TEXT or BLOB may help. I`ve ran into the same error on currently newest mysql server (5.7.21): MySQL: Error Code: 1118 Row size too large(> 8126). ![]()
