Hi,
I am facing some issues syncing Materialized Views into Lakebase with triggered mode, and I actually wonder if this is actually possible.
create materialized view some_catalog.some_schema.some_table
tblproperties(
'delta.enableChangeDataFeed' = 'true',
'pipelines.channel'='PREVIEW')
as
select * from some_catalog_src.some_schema_src.some_table_src limit 100;
I've already added params that are needed, you can see below

when trying to create synced table, I get following error:
Incremental sync for table some_catalog_src.some_schema_src.some_table_src requires Auto CDF to identify changes, which is only available in the PREVIEW channel. Set pipeline_channel = PREVIEW to proceed.
This materialized view is created manually, but I have also tested on MV created via SDP (in PREVIEW channel).
this works with tables:
create table some_catalog.some_schema.some_table_tbl
tblproperties(
'delta.enableChangeDataFeed' = 'true')
as
select * from some_catalog_src.some_schema_src.some_table_tbl_src limit 100;
The source for triggered sync needs to have CDF enabled:

and I believe I have this enabled, but just noticed it's in Private Preview, so will need to double check:

while I wrote this, I will leave it and double check if I have enabled CDF on MVs
