Statistics per year (includes multiples edits made to one record, does not include record addition or deletion)

Modules	mod-oai-pmh, edge-oai-pmh
What is implemented	OAI-PMH protocol (repository side)
Processes	initial harvesting (one-time actions) selective harvesting (scheduled action, predominantly once a day)
Ideal response size	0.5 - 2 MB as per Best Practices for Resumption Token. 2 MB response equals roughly 400-500 MARC records. One batch should be processed not more than 10 seconds so that 20 000 records (approximate records creates/updates per day) were harvested less than an hour.
Simultaneous harvesting processes	1-5
Availability	Maintenance could be performed once a week, but before scheduled for selective harvesting hours.

Modules	mod-rtac, edge-rtac
What is implemented	Microservice to allow 3rd party discovery services to determine the availability of FOLIO inventory.
Processes	EDS real-time check on items associated with instance by instance UUID
Number of requested instances UUIDs per time	1-50
Number of holdings record in one instance	maximum - be greater than 300 average - less than 10
Expected response time	Faster than 30 seconds for a list of 50 instances Faster than 5 seconds for 1 UUID with up to 300 instances
How many users at any given time	1-10
Availability	TBD
