I’m using Mysql with INNODB Engine and the row_format is Barracuda.
Now I have a table which has a PK column and lots of(about one hundred and eighty) columns with Text data type.
My question is If the table’s data get large what will the main performance issue or any disadvantages?
If you just store data in those TEXT columns – it’s acceptable. If you have indexes on those columns – use dictionary encoding for them.
