Greetings to all, and thanks for the excellent resource!
I have a question regarding indexing large tables (150M+ rows, 2.6G).
The tables in question have a format like this:
word_id mediumint unsigned
doc_id mediumint unsigned
Our indexes are as follows:
PRIMARY KEY (word_id, doc_id)
INDEX

Hello, everyone
I have the following situation:
After enjoying problems related to deleting a large portion of a table,
subsequent slow selects and such, I decided to do an alternate route when
removing data from a table:
The table had transactions for one year, and the table really only needs
Hi,
Instead of using separate CREATE INDEX statements, you can build all
your index at once with ALTER TABLE:
ALTER TABLE my_table
ADD INDEX ...,
ADD INDEX ... ,
ADD INDEX ... ;
Hope this helps,

Is there a way to change the directory used when mySQL
copies the table for creating indexes on large tables?
My tmp directory is partitioned for 509 megs and
adding an index via ATLER TABLE or CREATE TABLE yields

AFIAK, it is limitation of ext2 file sistem.
You can't create any file lager then 2GB on ext2.

Perhaps your index file (.MYI) is growing larger than 2GB, the file-size
limit on 2.2.x kernels?
Or, if you have moved the tables with symlinks, MySQL will put the new file
(most of the time?) in the configured data directory and not where the
symlink points.
