Database sharding vs partitioning

Question

I have been reading about scalable architectures recently. In that context, two words that keep on showing up with regards to databases are sharding and partitionin

Answer 1

Consider a Table in database with 1 Million rows and 100 columns In Partitioning you can divide the table into 2 or more table having property like:

1. 0.4 Million rows(table1), 0.6 million rows(table2)

2. 1 Million rows & 60 columns(table1) and 1 Million rows & 40 columns(table2)

   There could be multiple cases like that

This is general partitioning

But Sharding refer to 1st case only where we are dividing the data on the basis of rows. If we are dividing the table into multiple table we need to maintain multiple similar copies of schemas as now we have multiple tables.
