Release v0.11.0

v0.11.0

There is (1) breaking change in this release and it affects NATS users only.

(1) ⚠️ Breaking change for NATS users only

NATS subject pattern change

We changed the default NATS subject naming pattern to bring it in line with our other sinks.

The default NATS subject naming pattern has changed from:

Old pattern (v0.10.x and earlier):

sequin.changes.<database>.<schema>.<table>.<action>
sequin.rows.<database>.<schema>.<table>

New pattern (v0.11.0+):

sequin.<database>.<schema>.<table>.<action>

Example

If you were streaming changes from a products table in the public schema of a database called shop, subjects have changed from:

Before:

• sequin.changes.shop.public.products.insert
• sequin.changes.shop.public.products.update
• sequin.changes.shop.public.products.delete

After:

• sequin.shop.public.products.insert
• sequin.shop.public.products.update
• sequin.shop.public.products.delete

Migration for NATS users

Option 1: Update your NATS subscriptions

Update your NATS subscribers to use the new subject pattern:

# Old subscription
nats sub "sequin.changes.>"

# New subscription  
nats sub "sequin.>"

Option 2: Use a routing function to maintain the old pattern

If you prefer to keep the old subject pattern, you can use a routing function in your NATS sink:

def route(action, _record, _changes, metadata) do
  %{
    subject: "sequin.changes.#{metadata.database_name}.#{metadata.table_schema}.#{metadata.table_name}.#{action}",
  }
end

This allows you to customize the subject pattern to match your existing infrastructure without changing your NATS subscribers.

Features

• Add support for Routing functions to more sinks. They're now supported for Webhook, Redis String, and NATS sinks. The rest will be added shortly.
• Added metadata.database object to messages

Improvements

• Collate noisy logs into single, debounced log lines.
• Fixed logs around receiving first message from slot. Now, we will always only log one time.

Release v0.10.7

Release notes for v0.10.7

⚠️ Legacy webhook payloads are deprecated

For accounts created before 2024-11-06 and using Webhook sinks:

We have deprecated an older payload version which was active for webhook sinks in accounts created earlier than 2024-11-06. If this describes your webhook sink, the only change required to safely migrate is to set batch = false in the sink configuration card of your webhook sinks.

With batch = false set, you can safely migrate to v0.10.7 without changes to your delivered payloads.

IAC (YAML and API) changes

To support multiple tables in one sink the specification for YAML and API requests has changed.

schema: and table: are now source:

schema and table

sinks:
  - name: kafka-users-sink
    table: public.users
  - name: kafka-public-sink
     schema: public

And you want to maintain single schema or table functionality, you must change this to:

sinks:
  - name: kafka-users-sink
    source:
      include_tables: ["public.users"]
  - name: kafka-public-sink
    source:
      include_schemas: ["public"]

group_column_names is now under tables

Further, group_column_names is now specified per table and exists under the tables key:

sinks:
  - name: kafka-users-sink
    group_column_names: ["account_id"]

now becomes:

sinks:
  - name: kafka-users-sink
    tables:
      - name: users
        group_column_names: ["account_id"]

⚠️ Column filters are deprecated

Column filters are deprecated in v0.10.0 and you will be unable to migrate your Sequin instance from v0.9 or earlier to v0.10.0 or later if any of your sinks have column filters. Please replace your column filters with filter functions before upgrading your Sequin instance.

Migrating to filter functions

Let's say you have a column filter that compares a status column of type text to "active" like:

You can replace this column filter with the following filter function:

def filter(action, record, changes, metadata) do
  record["status"] == "active"
end

You can read more about filter functions in our docs.

Join our Discord or Slack communities if you would like the Sequin team to help with this migration.

Migration failure

If you attempt to migrate a Sequin instance that has column filters, you will receive an error such as:

** (Postgrex.Error) ERROR P0001 (raise_exception) Cannot migrate: Found 1 sink(s) with column filters that need to be removed first: products-sink
