max_concurrent_merge

int

The maximum number of allowed concurrent merge processes. A value of 0 for this property means that there is no limit to the number of concurrent merge processes running at any given time. This property sets a limit as to the number of concurrent merge processes that can be run against a merge publication at one time. If there are more snapshot processes scheduled at the same time than the value allows to run, then the excess jobs will be put into a queue and wait until a currently-running merge process finishes.

int

The maximum number of allowed concurrent filtered data snapshot sessions that can be running against the merge publication. If 0, there is no limit to the maximum number of concurrent filtered data snapshot sessions that can run simultaneously against the publication at any given time. This property sets a limit as to the number of concurrent snapshot processes that can be run against a merge publication at one time. If there are more snapshot processes scheduled at the same time than the value allows to run, then the excess jobs will be put into a queue and wait until a currently-running merge process finishes.

replicate_ddl

int

Indicates whether schema replication is supported for the publication.

0 = DDL statements are not replicated.

1 = DDL statements executed at the publisher are replicated.

For more information, see Making Schema Changes on Publication Databases.

allow_subscriber_initiated_snapshot

bit

Indicates that Subscribers can initiate the process that generates the snapshot for a publication using parameterized filters. 1 indicates that Subscribers can initiate the snapshot process.

dynamic_snapshot_queue_timeout

int

Specifies how many minutes a Subscriber must wait in the queue for the snapshot generation process to begin when using parameterized filters.

dynamic_snapshot_ready_timeout

Specifies how many minutes a Subscriber waits for the snapshot generation process to be completed when using parameterized filters.

distributor

sysname

The name of the Distributor for the publication.

snapshot_jobid

binary(16)

Identifies the agent job that generates the snapshot when the Subscriber can initiate the snapshot generation process.

allow_web_synchronization

bit

Specifies whether the publication is enabled for Web synchronization, where 1 means that Web synchronization is enabled for the publication.

web_synchronization_url

nvarchar(500)

Specifies the default value of the Internet URL used for Web synchronization.

allow_partition_realignment

bit

Indicates whether deletes are sent to the subscriber when modification of the row on the publisher causes it to change its partition.

0 = Data from an old partition will be left on the subscriber, where changes made to this data on the publisher will not replicate to this Subscriber, but changes made on the Subscriber will replicate to the Publisher.

1 = Deletes to the Subscriber to reflect the results of a partition change by removing data that is not longer part of the Subscriber's partition.

For more information, see sp_addmergepublication (Transact-SQL).

Data that remains at the Subscriber when this value is 0 should be treated as if it were read-only; however, this is not strictly enforced by the replication system.

retention_period_unit

tinyint

Defines the unit used when defining retention, which can be one of these values:

0 = Day.

1 = Week.
