Import from Redis

Before you beginCopy Anchor Link

Use a standalone Redis source reachable through public IPv4. The import service rejects private and reserved addresses. The source must allow PING, INFO, SCAN, EVAL, DUMP, and PTTL.

Stop source application writes and confirm the destination is empty. The importer copies a selected source database from 0–15 into destination database 0. Customer connections to the destination are temporarily unavailable during the import.

Run an importCopy Anchor Link

1. Open Import data on the destination memory database.
2. Enter the source host, port, username if required, password, and database number.
3. Configure TLS and an optional SNI server name. Keep certificate verification enabled for a verifiable source identity.
4. Confirm that writes are stopped and accept the destination connection interruption.
5. Submit the import and wait for completion.
6. Reconnect to the destination, verify expected keys and expiration behavior, and test the application before resuming normal traffic.

Enter the password literally, without URL encoding. The importer does not delete or modify source data.

Limits and recoveryCopy Anchor Link

Imports are limited to 100,000 keys, 512 MiB transferred, and 15 minutes. This is a one-time copy, not continuous replication.

A failed import can leave partial destination data. There is no automatic retry or rollback. Inspect the destination before deciding how to recover; do not repeatedly submit imports into a nonempty database.
