Evan Tschannen 866ccfe344 added the ability to allow the master to finish recovery before all storage servers in both regions have their mutations. This allows you to recover from scenarios where you lose all your tlogs in one dc. 2018-07-04 01:59:04 -04:00
Evan Tschannen a288d5b9a9 added a fallback satellite configuration, so that we can use two satellites if available, but do not have to failover to the remote datacenter if one satellite is down 2018-06-28 23:15:32 -07:00
Evan Tschannen a66eda8baa added the three_datacenter_fallback redundancy mode, which allows you to drop a down datacenter when configured in three_datacenter mode 2018-06-27 23:24:33 -07:00
Evan Tschannen 8a8914f046 re-added the ability to configure the number of log routers. Many log routers are needed to get a sufficient number of sockets involved in copying data across the WAN 2018-06-22 00:04:00 -07:00
Evan Tschannen 1ccfb3a0f4 fix: log_anti_quorum was always 0 in simulation
removed durableStorageQuorum, because it is no longer a useful configuration parameter

Evan Tschannen e8c462882b re-added remote_logs as a parameter, because it could be useful to have a different number of logs between when recruited as primary and remote 2018-06-18 10:22:34 -07:00
Evan Tschannen 0913368651 added usable_regions to specify if we will replicate into a remote region
remote replication defaults to the primary replication
removed remote_logs, because they should be specified as an override in the regions object

Evan Tschannen 0c6825eb43 allow multiple regions with the same priority
configurations must have at least one region with non-negative priority

Alex Miller 0042294566 MultiDC: Serialized JSON represents DC and Satellites in same array.
With a `"satellite": 1` property that differentiates them.  "satellite" will
likely also be deprecated in the future, but this is closer to what the final
serialized form will look like.

Alex Miller ac1fc3660d MultiDC: Regions JSON should represent datacenters as an array.
This is so that the serialized format released in 6.0 will already include a
required change, which is to support >1 DC per region.
