The following table provides Apache Cassandra configuration settings, database build commands, and stress test commands:
Table 6. Apache Cassandra settings
Number of physical servers | 5 |
Replication factor (RF) | 3 (default) |
Read consistency level | Local quorum |
Write consistency level | Local quorum |
Compression type | LZ4 (default) |
Compression chunk size | 64 KB (default) |
Cassandra Query Language (CQL) schema | Schema built with cqlstress-insanity-example.yaml. This schema is approximately 1.1 KB per partition uncompressed, and approximately 700 bytes compressed. |
Compaction type | LeveledCompactionStrategy |
Total number of database entries | 2 billion entries for the cqlstress-insanity-example.yaml schema, which requires approximately 3.5 TB of disk space for one copy of the database on the cluster. With an RF of 3, the total database size is approximately 10.5 TB. |
Java version | Latest Java 1.8 version supported by the operating system |
Benchmark tool | cassandra-stress |
Storage device file system | XFS |
Benchmark workloads | - Scenario 1: Uniform random 90 percent reads/10 percent writes
- Scenario 2: Uniform random 10 percent reads/90 percent writes
- Scenario 3: Uniform mix of 50 reads/50 percent writes
|
SLA | Median value of all three clients at 99th percentile latency of 10 milliseconds |
Key metric | Total operations per second and median SLA for all clients |
Test time | 10 minutes per run |
