Refactored GetTruncatedSwitchList to:
- Only fetch switches in the requested range
- Fetch switch members in bulk rather than one switch at a time
This uses a new GetSwitchMembersList method that requires the following indexes:
CREATE INDEX ix_switches_system
ON public.switches USING btree
(system ASC NULLS LAST)
INCLUDE("timestamp")
TABLESPACE pg_default;
CREATE INDEX ix_switch_members_switch
ON public.switch_members USING btree
(switch ASC NULLS LAST)
INCLUDE(member)
TABLESPACE pg_default;
- ImportSystem builds a mapping of data file HID to current system HID
- Switches in a data file are reconciled with system members' actual IDs using this mapping
- SwitchStore provides a RegisterSwitches method to register multiple switches
- RegisterSwitches only imports a switch if one does not exist with the same timestamp
- The number of switches created is logged
Instead of acquiring a connection per service per request, we
acquire connections more often but at a more granular level, meaning
they're also disposed of more quickly instead of staying for a long time
in case of long-running commands or leaks.
