uptasticsearch development version

uptasticsearch 0.4.0

Features

Added support for ES7.x

• #161 Added support for ES7.x. The biggest changes between that major version and 6.x were the removal of _all as a way to reference all indices, changing the response format of hits.total into an object like {"hits": {"total": 50}}, and restricting all indices to have a single type of document. More details can be found at https://www.elastic.co/guide/en/elasticsearch/reference/current/breaking-changes-7.0.html.

uptasticsearch 0.3.1

Bugfixes

Minor changes to unit tests to comply with CRAN

• #136 removed calls to closeAllConnections() in unit tests because they were superfluous and causing problems on certain operating systems in the CRAN check farm.

Changed strategy for removing duplicate records

• #138 changed our strategy for deduping records from unique(outDT) to unique(outDT, by = "_id"). This was prompted by Rdatatable/data.table#3332 (changes in data.table 1.12.0), but it’s actually faster and safer anyway!

uptasticsearch 0.3.0

Features

Full support for ES6.x

• #64 added support for ES6.x. The biggest change between that major version and v5.x is that as of ES6.x all requests issued to the ES HTTP API must pass an explicit Content-Type header. Previous versions of ES tried to guess the Content-Type when none was declared
• #66 completed support for ES6.x. ES6.x changed the supported strategy for issuing scrolling requests. uptasticsearch will now hit the cluster to try to figure out which version of ES it is running, then use the appropriate scrolling strategy.

Bugfixes

get_fields when your index has no aliases

• previously, get_fields broke on some legacy versions of Elasticsearch where no aliases had been created. The response on the _cat/aliases endpoint has changed from major version to major version. #66 fixed this for all major versions of ES from 1.0 to 6.2

get_fields when your index has multiple aliases

• previously, if you had multiple aliases pointing to the same physical index, get_fields would only return one of those. As of #73, mappings for the underlying physical index will now be duplicated once per alias in the table returned by get_fields.

bad parsing of ES major version

• as of #64, uptasticsearch attempts to query the ES host to figure out what major version of Elasticsearch is running there. Implementation errors in that PR led to versions being parsed incorrectly but silently passing tests. This was fixed in #66. NOTE: this only impacted the dev version of the library on Github.

ignore_scroll_restriction not being respected

• In previous versions of uptasticsearch, the value passed to es_search for ignore_scroll_restriction was not actually respected. This was possible because an internal function had defaults specified, so we never caught the fact that that value wasn’t getting passed through. #66 instituted the practice of not specifying defaults on function arguments in internal functions, so similar bugs won’t be able to silently get through testing in the future.

Deprecations and Removals

• #69 added a deprecation warning on get_counts. This function was outside the core mission of the package and exposed us unnecessarily to changes in the Elasticsearch DSL

uptasticsearch 0.2.0

Features

Faster unpack_nested_data

• #51 changed the parsing strategy for nested data and made it 9x faster than the previous implementation

Retry logic

• Functions that make HTTP calls will now use retry logic via httr::RETRY instead of one-shot POST or GET calls

uptasticsearch 0.1.0

Features

Elasticsearch metadata

• get_fields returns a data.table with the names and types of all indexed fields across one or more indices

Routing Temporary File Writing

• es_search now accepts an intermediates_dir parameter, giving users control over the directory used for temporary I/O at query time

Bugfixes

Empty Results

• Added logic to short-circuit and return early with an informative message if a query matches 0 documents

uptasticsearch 0.0.2

Features

Main function

• es_search executes an ES query and gets a data.table

Parse raw JSON into data.table

• chomp_aggs converts a raw aggs JSON to data.table
• chomp_hits converts a raw hits JSON to data.table

Utilities

• unpack_nested_data deals with nested Elasticsearch data not in a tabular format
• parse_date_time parses date-times from Elasticsearch records

Exploratory functions

• get_counts examines the distribution of distinct values for a field in Elasticsearch
