A table in ClickHouse consists of data parts sorted by the user's specified primary key (by default, the ORDER BY clause on table creation but see Index Design for the details). When data is inserted in a table, separate data parts are created, and each of them is lexicographically sorted by primary key. For example, if the primary key is (CounterID, Date), the data in the part is sorted first by CounterID, and within each CounterID value by Date. In the background, ClickHouse merges data parts for more efficient storage, similar to a Log-structured merge tree.
