DB cluster parameters in Aurora PostgreSQL Limitless Database

You can use the following DB cluster parameters to configure Aurora PostgreSQL Limitless Database.

rds_aurora.limitless_adaptive_fetch_size

Enhances batch prefetching. When set to true, this parameter allows a self-adjusting (adaptive) fetch size for prefetching. When set to false, the fetch size is constant.

rds_aurora.limitless_auto_scale_options

Sets the options available for adding routers or splitting shards in a DB shard group. The value can be add_router, split_shard, or both.

For more information, see Adding a router to a DB shard group and Splitting a shard in a DB shard group.

rds_aurora.limitless_distributed_deadlock_timeout

The amount of time to wait on a lock before checking whether there is a distributed deadlock condition, in milliseconds. The default is 1000 (1 second).

For more information, see Distributed deadlocks in Aurora PostgreSQL Limitless Database.

rds_aurora.limitless_enable_auto_scale

Enables the adding of routers and splitting of shards in a DB shard group.

For more information, see Adding a router to a DB shard group and Splitting a shard in a DB shard group.

rds_aurora.limitless_finalize_split_shard_mode

Determines how system-initiated shard splits are finalized. For more information, see Splitting a shard in a DB shard group.

rds_aurora.limitless_maximum_adaptive_fetch_size

Sets the upper limit for the adaptive fetch size. The range is 1–INT_MAX. The default is 1000.
