* Parallel bulk indexing of documents into Elasticsearch
* reduce memory consumption when building JSON requests
* no need to change type of column PROJECT_MEASURES.MEASURE_DATE as it is not used
* fix created_at/updated_at fields of manual_measure when saved from Rails
* remove usage of deprecated delete-by-query
