Sharding a database table before it has been optimized locally causes premature complexity. Sharding should be used only when all other options for optimization are inadequate. The introduced complexity of database sharding causes the following potential problems:
Increased complexity of SQL - Increased bugs because the developers have to write more complicated SQL to handle sharding logic.
Sharding introduces complexity - The sharding software that partitions, balances, coordinates, and ensures integrity can fail.
Single point of failure - Corruption of one shard due to network/hardware/systems problems causes failure of the entire table.
Failover servers more complex - Failover servers must themselves have copies of the fleets of database shards.
Backups more complex - Database backups of the individual shards must coordinated with the backups of the other shards.
Operational complexity added - Adding/removing indexes, adding/deleting columns, modifying the schema become much more difficult.

sharding 40 up, 14 down
Splitting a database into several pieces, usually to improve the speed and reliability of your application.
Sharding strictly speaking is a synonym for "horizontal partitioning" or dividing up a database table by its rows.
In common use, sharding refers to having some data for an app on one database server, and other data in another. Often this is done by having specific tables hosted on specific servers, with a function determining which server contains the information being requested.
Sharding is frequently discussed with regard to large web based applications, but is not limited to any particular industry.
As a practical example, a WordPress MultiSite installation hosting several hundred thousand blogs could have the tables for sites 1-100,000 running on one database server 100,001-200,000 on another or 200,001+ on a third. An alternative sharding implementation could be to have the 50 busiest blogs' tables split between the first two servers all remaining blog data on the third server. Likewise, data could be partitioned based upon the geographic location of the web servers delivering each blog.
When our site became so popular it kept overwhelming our database servers, we looked into sharding the database between five different data centers.
Oh. I see.[SIGPIC][/SIGPIC]0 -

It's probably the 3 eastern servers. They crash a lot, enough crashes later and they finally broke.[SIGPIC][/SIGPIC]0
