This doesn't look like a mysql problem per-se. It looks like the
problem lies with connection pooling somewhere in your Java stack;
it looks like Pentaho's connection pooling is misconfigured alloing
stale connections to remain in the pool. I suggest that you take this
query to a Pentaho support
I'm sorry Michael and list mysql ,

Hello,
I've been noticing a little lag in my application lately, it seems as
if 1 table in 1 database is getting slower to read from. Mind you,
that table is being accessed a LOT of times per second every hour of
every day, and then the application searches on this same table too.
In my

Take a look at the output of: iostate -xk 60
The output will update every 60 secs. Take a look at the value in the %util
column after a few updates, if it's around 90% you have become disk bound
and you'll need to figure out a way to decrease some load on the disk.

The behaviour of mixed reads/write o your system is heavily dependant
on what types of tables you are using. The fully ACID tables types,
most notably InnoDB support that model far better than MyISAM tables..
Not to discount the value of measuring your raw i/o performance, but
first we should

All,
I have a very large table. It has about 1 billion rows. Initially
everything was fine. But now the table is a bit slow. Loaded takes a lot
of time. I usually load in chunks of 22 million rows.
Is the size of the table any way related to the performance? I am not
sure about this.

What is the table type for Table?
Firstly check with queries and index if required. Check if queries using
this table can be fine tuned. Check if table getting locked.
If size of table is problem and if the table type is innodb check for
innodb_file_per_table options. Also have a look for
15 matches
