build_time_map_keys_parallel: Build time_map keys (in parallel)

In aarmiller/smallDB: This package provides functions for working with the small databases

Build time_map keys (in parallel)

Description

This function goes to the database and assembles all of the inpatient an outpatient visits (or just the visits specified by a collection table). It then assembles them into a logintudinal time_map of distinct visits (defined by admission/service date and stdplac). Finally, each visit is given a distinct visit key. The time_map and the distinct inpatient and outpatient visit keys are returned as a list. NOTE: This function should generally only be run once after the small DB is build, and it generally should not be called directly. Use the function 'add_time_map_keys()' to add the time_map keys to the database.

Usage

build_time_map_keys_parallel(
  collect_tab = collect_table(),
  db_path,
  db_con,
  num_cores = NULL
)

Arguments

collect_tab	a collection table to build time_map from. By default all years will be used
db_path	Path to the database
db_con	a connection to a database#'
num_cores	The number of worker cores to use. If not specified will use 10. If NULL is specified then it will determine the number of cores based on the which ever is the smallest value between number of rows in for collect_tab or detected number of cores - 1

Value

A list containing three tibbles (timemap, outpatient keys, and inpatient keys)
