v0.11.0 Release
Please upgrade your Cadence server to add the new default search attribute:
cadence admin cluster add-search-attr --search_attr_key BinaryChecksums --search_attr_type 1
Schema version check is enforced, please use the sql tool to add schema enforcing tables.
For MySQL:
./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql --db cadence setup-schema -v 0.3
./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql --db cadence_visibility setup-schema -v 0.1
NOTE: Assuming you are at 0.10.x right now, the cadence schema version should be 0.3 and visibility should be 0.1.
