The section [system] in risingwave.toml. All these fields are used to initialize the system parameters persisted in Meta store. Most fields are for testing purpose only and should not be documented.

Fields

barrier_interval_ms: Option<u32>

The interval of periodic barrier.

checkpoint_frequency: Option<u64>

There will be a checkpoint for every n barriers.

sstable_size_mb: Option<u32>

Target size of the Sstable.

parallel_compact_size_mb: Option<u32>

The size of parallel task for one compact/flush job.

block_size_kb: Option<u32>

Size of each block in bytes in SST.

bloom_false_positive: Option<f64>

DEPRECATED: Bloom filter is no longer a supported SST filter implementation. This field is kept for backward compatibility and no longer controls whether SST filters are emitted.

state_store: Option<String>

URL for the state store

data_directory: Option<String>

Remote directory for storing data and metadata objects.

backup_storage_url: Option<String>

Remote storage url for storing snapshots.

backup_storage_directory: Option<String>

Remote directory for storing snapshots.

max_concurrent_creating_streaming_jobs: Option<u32>

Max number of concurrent creating streaming jobs.

pause_on_next_bootstrap: Option<bool>

Whether to pause all data sources on next bootstrap.

enable_tracing: Option<bool>

Whether to enable distributed tracing.

use_new_object_prefix_strategy: Option<bool>

Whether to split object prefix.

license_key: Option<LicenseKey>

The license key to activate enterprise features.

time_travel_retention_ms: Option<u64>

The data retention period for time travel.

per_database_isolation: Option<bool>

Whether per database isolation is enabled

enforce_secret: Option<bool>

Whether to enforce secret on cloud.
