Expand description

The subsection [storage.data_file_cache] and [storage.meta_file_cache] in risingwave.toml.

It’s put at StorageConfig::data_file_cache and StorageConfig::meta_file_cache.

Fields§

§dir: String§capacity_mb: usize§file_capacity_mb: usize§flushers: usize§reclaimers: usize§recover_concurrency: usize§insert_rate_limit_mb: usize

Deprecated soon. Please use throttle to do I/O throttling instead.

§indexer_shards: usize§compression: Compression§flush_buffer_threshold_mb: Option<usize>§throttle: Throttle§fifo_probation_ratio: f64§blob_index_size_kb: usize

Set the blob index size for each blob.

A larger blob index size can hold more blob entries, but it will also increase the io size of each blob part write.

NOTE:

  • The size will be aligned up to a multiplier of 4K.
  • Modifying this configuration will invalidate all existing file cache data.

Default: 16 KiB

§recover_mode: RecoverMode

Recover mode.

Options:

  • “None”: Do not recover disk cache.
  • “Quiet”: Recover disk cache and skip errors.
  • “Strict”: Recover disk cache and panic on errors.

More details, see [RecoverMode::None], [RecoverMode::Quiet] and [RecoverMode::Strict],
