Installation
You can install DVC data via pip from PyPI:
$ pip install dvc-dataUsage
HashFile
HashFile
Based on dvc-object’s Object, this is an object that has a particular hash that can be used to verify its contents. Similar to git’s ShaFile.
from dvc_data.hashfile import HashFile
obj = HashFile("/path/to/file", fs, HashInfo("md5", "36eba1e1e343279857ea7f69a597324e")HashFileDB
Based on dvc-object’s ObjectDB, but stores HashFile objects and so is able to verify their contents by their hash_info. Similar to git’s ObjectStore.
from dvc_data.hashfile import HashFileDB
odb = HashFileDB(fs, "/path/to/odb")Index
Index
A trie-like structure that represents data files and directories.
from dvc_data.index import DataIndex, DataIndexEntry
index = DataIndex()
index[("foo",)] = DataIndexEntry(hash_info=hash_info, meta=meta)Storage
A mapping that describes where to find data contents for index entries. Can be either ObjectStorage for HashFileDB-based storage or FileStorage for backup-like plain file storage.
index.storage_map[("foo",)] = ObjectStorage(...)Contributing
