Question

Here is my schema :

create_table "delayed_jobs", :force => true do |t|
    t.integer  "priority",   :default => 0
    t.integer  "attempts",   :default => 0
    t.text     "handler"
    t.text     "last_error"
    t.datetime "run_at"
    t.datetime "locked_at"
    t.datetime "failed_at"
    t.string   "locked_by"
    t.string   "queue"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

I am using delayed job for emails. One of my emails has a very long handler (50000+) characters and this happens to be cut off while it is saved in the handler text field. How many characters can a text field typically take and how should I increase it?

Answer 1

MySQL supports 4 TEXT field types

(TINYTEXT, TEXT, MEDIUMTEXT and LONGTEXT)

The limits for each type is

> TINYTEXT  256 bytes     TEXT  65,535 bytes     MEDIUMTEXT  16,777,215 bytes   
> LONGTEXT  4,294,967,295 bytes

You can change accordingly.
Note : Size in bytes is number of chars
