sync_local_data_batches: Synchronize Local Data From In-Memory Batches

In investdatar: Investment Data Access and Preparation Toolkit

Synchronize Local Data From In-Memory Batches

Description

Combines multiple freshly retrieved data batches in memory, de-duplicates them by key_cols, then calls sync_local_data() once. This is useful for gap repair workflows where calling sync_local_data() once per small page would repeatedly rewrite the same local .rds file.

Usage

sync_local_data_batches(
  batches,
  local_file_path,
  key_cols,
  order_cols = key_cols,
  source_utime = NULL,
  local_updated_at = Sys.time()
)

Arguments

batches	A list of data.table-compatible batches.
local_file_path	Output .rds file path.
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.

Value

A sync result list.
