Cluster Configuration Options
number
default:3
This is the minimum number of gateway nodes that can be deployed. Note that the minimum number of gateway nodes is 3
number
default:5
This is the maximum number of gateway nodes that can be deployed.
number
default:3
This is the minimum number of database nodes that can be deployed.
number
default:5
This is the maximum number of database nodes that can be deployed.
milliseconds
default:200
Controls how often data is flushed from memory (memtable) to disk as SST files.
- Lower values: Better durability (less data loss on crash), but increased disk I/O
- Higher values: Better write throughput, but more data at risk in memory
bytes
Target size for SST files created at Level 0 during flush operations.
- Larger values: Fewer files created, reduced compaction overhead, but longer individual flush times
- Smaller values: More granular files, faster flushes, but more compaction work
milliseconds
default:50
How frequently the system checks for new data or events.
- Lower values: More responsive to changes, but higher CPU usage
- Higher values: Reduced CPU overhead, but increased latency for detecting changes
number
default:100
Maximum number of SST files allowed at Level 0 before compaction is triggered.
- Higher values: Better sustained write throughput, but slower read performance (more files to search)
- Lower values: Faster reads, but more frequent compaction and write amplification
number
default:100
Maximum L0 SST files for the vector index (separate from graph data).
- Higher values: Better vector ingestion throughput during bulk loads
- Lower values: Faster vector similarity searches, but more compaction during writes
bytes
Memory allocated for caching frequently accessed vectors.
- Higher values: Faster vector queries (more cache hits), reduced disk I/O
- Lower values: Lower memory footprint, but slower queries due to more disk reads
