Manifest syntax for Spicepods

About YAML syntax for Spicepod manifests (spicepod.yaml)​

Spicepod manifests use YAML syntax and must be named spicepod.yaml or spicepod.yml. If you're new to YAML and want to learn more, see "Learn YAML in Y minutes."

Spicepod manifest files are stored in the root directory of your application code.

version​

The version of the Spicepod manifest. The current version is v1beta1.

kind​

The kind of Spicepod manifest. The kind is Spicepod.

name​

The name of the Spicepod.

secrets​

The secrets section in the Spicepod manifest is optional and is used to configure how secrets are stored and accessed by the Spicepod. Learn more.

secrets.from​

The from field is a string that represents the Uniform Resource Identifier (URI) for the secret store. This URI is composed of two parts: a prefix indicating the Secret Store to use, and an optional selector that specifies the secret to retrieve.

The syntax for the from field is as follows:

from: <secret_store>:<selector>

Where:

  • <secret_store>: The Secret Store to use

    Currently supported secret stores:

    If no secret stores are explicitly specified, it defaults to env.

  • <selector>: The secret within the secret store to load.

The type of secret store for reading secrets.

Example

secrets:
  - from: env
    name: env

secrets.name​

The name of the secret store. This is used to reference the store in the secret replacement syntax, ${<secret_store_name>:<key_name>}.

runtime​

num_of_parallel_loading_at_start_up​

This configuration setting determines the maximum number of datasets that can be loaded in parallel during startup. This parallel loading capability accelerates Spice's startup process when multiple datasets are configured.

results_cache​

The results cache section specifies runtime cache configuration. Learn more.

runtime:
  results_cache:
    enabled: true
    cache_max_size: 128MiB
    eviction_policy: lru
    item_ttl: 1s
  • enabled - optional, true by default
  • cache_max_size - optional, maximum cache size. Default is 128MiB
  • eviction_policy - optional, cache replacement policy when the cached data reaches the cache_max_size. Default is lru - least-recently-used (LRU)
  • item_ttl - optional, cache entry expiration time, 1 second by default.

metadata​

An optional map of metadata.

Example

metadata:
  epoch_time: 1605312000
  period: 72h
  interval: 1m
  granularity: 10s
  episodes: 10

datasets​

A Spicepod can contain one or more datasets referenced by relative path.

Example

A datasets referenced by relative path.

datasets:
  - ref: datasets/uniswap_v2_eth_usdc

A dataset defined inline.

datasets:
  - from: spice.ai/eth.recent_blocks
    name: eth_blocks
    acceleration:
      enabled: true
      refresh_mode: full
      refresh_check_interval: 1h

models​

A Spicepod can contain one or more models referenced by relative path.

Example

A model referenced by path.

models:
  - from: models/drive_stats

A model defined inline.

models:
  - from: spiceai/lukekim/smart/models/drive_stats:latest
    name: drive_stats
    datasets:
      - drive_stats_inferencing

embeddings​

A Spicepod can contain one or more embeddings referenced by relative path.

Example

An embeddings model referenced by path.

embeddings:
  - from: embeddings/openai_text_embedding_3

An embedding defined inline.

embeddings:
  - name: hf_baai_bge
    from: huggingface:huggingface.co/BAAI/bge-small-en-v1.5
