C-Store is a read-optimized relational DBMS that contrasts sharply
|
||
|
|
with most current systems, which are write-optimized. Among the many
|
||
|
|
differences in its design are:
|
||
|
|
|
||
|
|
+ storage of data by column rather than by row,
|
||
|
|
|
||
|
|
+ careful coding and packing of objects into storage including main
|
||
|
|
memory during query processing,
|
||
|
|
|
||
|
|
+ storing an overlapping collection of column-oriented projections,
|
||
|
|
rather than the current fare of tables and indexes,
|
||
|
|
|
||
|
|
+ a non-traditional implementation of transactions which includes high
|
||
|
|
availability and snapshot isolation for read-only transactions,
|
||
|
|
|
||
|
|
+ and the extensive use of bitmap indexes to complement B-tree
|
||
|
|
structures.
