We’ve introduced two new features to improve connector reliability and support more database environments:

🔒 𝐑𝐞𝐚𝐝-𝐎𝐧𝐥𝐲 𝐒𝐧𝐚𝐩𝐬𝐡𝐨𝐭 𝐒𝐮𝐩𝐩𝐨𝐫𝐭

Connectors can now be configured to operate in read-only mode

✅ Zero-impact backups – avoids load and locks on the  primary.

💸 Cost efficiency – snapshot from cheaper or isolated infrastructure.

⚡ Faster test environments – quick cloning without write interference.

👉 Ideal for read replicas or any write-restricted database.

✔️ 𝐄𝐧𝐚𝐛𝐥𝐞𝐝 𝐯𝐢𝐚:

Set ʀᴇᴀᴅ ᴏɴʟʏ = ʏᴇs during connector setup

✔️ 𝐇𝐨𝐰 𝐢𝐭 𝐰𝐨𝐫𝐤𝐬:

‣ Snapshots are taken without modifying the source database

‣ No signal tables or locks required

‣ Safe to use in read-only or compliance-sensitive environments

🫀 𝐑𝐞𝐚𝐝-𝐎𝐧𝐥𝐲 𝐇𝐞𝐚𝐫𝐭𝐛𝐞𝐚𝐭 𝐄𝐯𝐞𝐧𝐭𝐬

❤️ Always responsive – connectors stay active even when source tables are quiet

🧠 Better visibility  – consistent health checks and status visibility

⚡ Faster issue detection – detect broken connections without waiting for data

👉 Ideal for low-activity sources or intermittent traffic

✔️ 𝐄𝐧𝐚𝐛𝐥𝐞𝐝 𝐯𝐢𝐚:

Toggle ʜᴇᴀʀᴛʙᴇᴀᴛ in the connector settings

✔️ 𝐇𝐨𝐰 𝐢𝐭 𝐰𝐨𝐫𝐤𝐬:

‣ Periodically emits a lightweight event from the connector

‣ Helps prevent replication lag or stuck offsets

These updates are available now across all connectors. Drop your feedback or questions—we’re listening!
