zip Key-Value Store driver¶

The zip driver implements support for reading from ZIP format files on top of a base key-value store. (Not all ZIP features are supported.)

json kvstore/zip : object¶

Read-only adapter for the ZIP archive format.

JSON specification of the key-value store.

Extends:¶

• KvStore — Key-value store specification.

Required members:¶

driver : "zip"¶

base : KvStore¶

Underlying key-value store with path to a ZIP file.

Optional members:¶

path : string¶

Key prefix within the key-value store.

If the prefix is intended to correspond to a Unix-style directory path, it should end with "/".

context : Context¶

Specifies context resources that augment/override the parent context.

cache_pool : ContextResource = "cache_pool"¶

Specifies or references a previously defined Context.cache_pool. It is typically more convenient to specify a default cache_pool in the context.

data_copy_concurrency : ContextResource = "data_copy_concurrency"¶

Specifies or references a previously defined Context.data_copy_concurrency. It is typically more convenient to specify a default data_copy_concurrency in the context.

Example JSON specifications¶

{ "driver": "zip",
  "kvstore": "gs://my-bucket/path/to/file.zip" }

Limitations¶

Writing is not supported, nor are all ZIP compression formats.
