two-way-sync

Two-Way Sync

Fetch records from two systems in parallel, compute differences via a shell script, and upsert each difference to the appropriate target system.

Inputs

Param	Type	Required	Description
system_a_url	string	yes	API endpoint to fetch records from system A
system_b_url	string	yes	API endpoint to fetch records from system B
upsert_a_url	string	yes	API endpoint to upsert records into system A
upsert_b_url	string	yes	API endpoint to upsert records into system B

Steps

fetch-both (parallel: fetch-a + fetch-b) -> compute-diff -> sync-diffs (loop) -> log-result

Features

• Parallel fetch from two systems simultaneously
• Shell script diff compares records and identifies mismatches
• Loop iterates over each difference and upserts to the correct target
• Retry with exponential backoff on fetches, linear on upserts
