Fields

backend: StorageBackendConfig

cache_mib: Option<u64>

The maximum size of the in-memory storage cache, in MiB.

If set, the specified cache size is spread across all the foreground and background threads. If unset, each foreground or background thread cache is limited to 256 MiB.

compression: StorageCompression

min_step_storage_bytes: Option<u64>

For a batch of data passed through the pipeline during a single step, the minimum estimated number of bytes to write it to storage.

This is provided for debugging and fine-tuning and should ordinarily be left unset. A value of 0 will write even empty batches to storage, and nonzero values provide a threshold. usize::MAX, the default, effectively disables storage for such batches. If it is set to another value, it should ordinarily be greater than or equal to min_storage_bytes.

min_storage_bytes: Option<u64>

For a batch of data maintained as part of a persistent index during a pipeline run, the minimum estimated number of bytes to write it to storage.

This is provided for debugging and fine-tuning and should ordinarily be left unset.

A value of 0 will write even empty batches to storage, and nonzero values provide a threshold. usize::MAX would effectively disable storage for such batches. The default is 10,048,576 (10 MiB).
