I now use v5.0.0, and I find that the range of excluded tables is smaller
than v5.0.0-beta, v5.0.0 only excludes getAllActualTables
Therefore, 5.0.0 initialized more tables metadata and the project started
more slowly
In a database with many tables, only one table is used for sharding, and the
other tables are not used by shardingsphere at all. How can the project be
started more quickly?
Thanks.
SingleTableRule class:
private Collection<String> getExcludedTables(final
Collection<ShardingSphereRule> rules) {
return rules.stream().filter(each -> each instanceof
DataNodeContainedRule).flatMap(each -> ((DataNodeContainedRule)
each).getAllTables().stream()).collect(Collectors.toSet());
}
