Release Release 2.1.1 (stateful failover) · tarantool/cartridge

[2.1.1] - 2020-04-20

Implement stateful failover mode. You can read more in "Failover
architecture" documentation topic (see failover.md).
Respect box.cfg options wal_dir, memtx_dir, vinyl_dir. They
can be either absolute or relative - in the later case it's calculated
relative to cartridge.workdir.
New option in cartridge.cfg({upgrade_schema=...})
to automatically upgrade schema to modern tarantool version
(only for leader). It also has been added for argparse.
Extend GraphQL issues API with various topics: replication,
failover, memory, clock. Make thresholds configurable via
argparse.

Make GraphQL validation stricter: scalar values can't have
sub-selections; composite types must have sub-selections; omitting
non-nullable arguments in variable list is forbidden. Your code may
be affected if it doesn't conform GraphQL specification.
GraphQL query auth_params returns "fullname" (if it was specified)
instead of "username".
Update errors dependency to 2.1.3.
Update ddl dependency to 1.1.0.

Lua API:

GraphQL API:

query {cluster {failover} } -> query {cluster {failover_params {...} } }
mutation {cluster {failover()} } -> mutation {cluster {failover_params() {...} } }

mutation($uuid: String!) {
  cluster { edit_topology(servers: [{uuid: $uuid ...}]) {} }
}
