Can a row filter be used in transactional replication?
Transactional replication allows you to replicate an indexed view as a view or as a table. If you replicate the view as a table, you cannot filter columns from the table. Row filters are not designed to work across databases.
What are the different types of filter in replication?
Replication offers four types of filters: Static row filters, which are available with all types of replication. Column filters, which are available with all types of replication. Parameterized row filters, which are available only with merge replication. Join filters, which are available only with merge replication.
How to use parameterized row filters in Merge Replication?
With merge replication, use parameterized row filters rather than creating multiple publications with static row filters. For more information, see Parameterized Row Filters. To define or modify a static row filter, see Define and Modify a Static Row Filter.
How to enable the Blackhole storage engine in MySQL?
To enable the BLACKHOLE storage engine if you build MySQL from source, invoke CMake with the -DWITH_BLACKHOLE_STORAGE_ENGINE option. To examine the source for the BLACKHOLE engine, look in the sql directory of a MySQL source distribution.
When to avoid row filters in transactional publications?
Row filters in transactional publications should be avoided if each replication node can support the full data load, and the overall data set is reasonably small. With merge replication, use parameterized row filters rather than creating multiple publications with static row filters. For more information, see Parameterized Row Filters.
When to use article filter in SQL Server?
Note: Row filters in transactional publications can add significant overhead, because the article filter clause is evaluated for each log row written for a published table to determine whether the row should be replicated. So this should be used with proper performance testing.
Why are transactional replication restrictions in SQL Server?
Suppose we have a centralized SQL Server OLTP database that stores data from transactions produced across the globe. For reporting purposes we need to segment the data only for a particular location as well as exclude any sensitive data. So the replication restrictions are based on the following:
Can a column filter be used in Merge Replication?
Column filters, which are available with all types of replication. Using column filters, you can choose a subset of columns to be published. For more information, see the section “Column Filters” in this topic. Parameterized row filters, which are available only with merge replication.
Who is the subscriber in transactional replication?
The Publisher or Subscriber is a non- SQL Server database, such as Oracle. By default, Subscribers to transactional publications should be treated as read-only, because changes are not propagated back to the Publisher. However, transactional replication does offer options that allow updates at the Subscriber.
