ClickHouse, as an open-source analysis database, is known for being fast. Is that true? Let’s test and verify it through comparative test. ClickHouse vs Oracle First of all, we conduct a comparative test on ClickHouse (CH for short) and Oracle database (ORA for short) under the same hardware and software environment, and use the internationally recognized TPC-H as the test benchmark. The test is to execute the calculation requirements (Q1 to Q22) defined with 22 SQL statements for 8 tables. The test is performed on one machine within 12 threads, and the total data amount is around 100G. Since the

The open-source analytical database ClickHouse (CH) is hot recently and is said to be exceptionally fast for performing OLAP analyses. Many users suffering from performance problems are eager to have a try. Does the DBMS really meet our expectations? The following performance test will tell us. Our subjects for comparisons are CH, Oracle (Ora in the following sections), and the open-source esProc SPL. The benchmark is the internationally acknowledged TPC-H. The test is based on 8 tables, tasked with achieving computations defined by 22 SQL statements (Q1-Q22), and compares times spent in finishing the computations with CH, Ora, and SPL
