nodbi 0.10.1

CRAN release: 2024-02-04

Bug fix

nodbi 0.10.0

CRAN release: 2024-01-21

Deprecated

  • empty parameter query now triggers a warning as it should be a valid JSON string; change query = "" into query = "{}"

Changes

  • adapted to use new, faster JSONB functions in SQLite 3.45.0 (RSQLite >= 2.3.4.9005)
  • refactored parts of docdb_create() to speed up handling large data frames and lists
  • made Elasticsearch to immediately refresh index after docdb_create() and other functions
  • docdb_update() now reports which records failed to update and then continues
  • docdb_delete() now returns harmonised success logical value across backends

Potentially breaking change

docdb_query() reimplementation to have the same functionality across all databases (DuckDB, SQLite, PostgreSQL, MongoDB, Elasticsearch, CouchDB); even though the API and unit tests remained, user provisions may break e.g. to handle return values of databases that previously were incompletely implemented (in particular Elasticsearch and CouchDB). Details:

  • query can now be complex (nested, various operators) and is digested with a Javascript helper
  • fields can now be nested fields (e.g., friends.name) to directly return values lifted from the nested field
  • listfields parameter newly implemented to return dot paths for all fields of all or selected documents in collection
  • expanded use of jq via jqr for mangling parameters, selecting documents, filtering fields and lifting nested field values
  • if no data are found, returns NULL (previously some backends returned an empty data frame)
  • docdb_query(src, key, query = "{}", fields = "{}") now delegates to docdb_get(src, key)
  • _id is always returned, unless specified with "_id": 0 in parameter fields
  • for scr_postgres, only fewer than 50 fields if any can be specified in fields
  • for src_sqlite, minimise the use of the time-costly json_tree
  • workaround for path collisions of MongoDB
  • some acceleration of docdb_query()
  • factored out common code
  • expanded testing
  • updated docs
