sync_local_data_partitioned: Synchronize Monthly Partitioned Local Data

In investdatar: Investment Data Access and Preparation Toolkit

Synchronize Monthly Partitioned Local Data

Description

Upserts only monthly partitions touched by new_data. On the first partitioned sync, an existing monolithic RDS cache is copied into monthly partitions so callers can opt in without a separate migration step.

Usage

sync_local_data_partitioned(
  new_data,
  local_file_path,
  time_col,
  key_cols,
  order_cols = key_cols,
  source_utime = NULL,
  local_updated_at = Sys.time(),
  tz = "UTC"
)

Arguments

new_data	A data.table-compatible object.
local_file_path	Output .rds file path.
time_col	Name of the timestamp column used for monthly partitioning.
key_cols	Character vector of key columns used for de-duplication.
order_cols	Character vector used to sort the merged data.
source_utime	Optional upstream update time recorded in metadata.
local_updated_at	Optional local update time override.
tz	Time zone used to determine month boundaries.

Value

A sync result list. Its data element contains the touched rows, rather than the complete potentially large dataset.
