Overview

Service that executes a standard (locking) REFRESH MATERIALIZED VIEW.

This is the safest option for simple or low-frequency updates where blocking reads during refresh is acceptable.

Options:

• row_count_strategy: (Symbol, default: :none) → one of :estimated, :exact, or :none or nil to control row count reporting

Returns a Smriti::ServiceResponse

Examples:

Direct usage

svc = Smriti::Services::RegularRefresh.new(definition, **options)
response = svc.call
response.success? # => true/false

via job, this is the typical usage and will create a run record in the DB

When definition.refresh_strategy == "concurrent"
Smriti::Jobs::Adapter.enqueue(Smriti::Services::RegularRefresh, definition.id, **options)

• ConcurrentRefresh
