Example 1 with TableSpaceSharding

use of org.nustaq.reallive.impl.tablespace.TableSpaceSharding in project kontraktor by RuedigerMoeller.

the class DataClient method connect.

public IPromise connect(DataCfg config, TableSpaceActor[] shards, ServiceActor hostingService) {
    this.config = config;
    this.hostingService = hostingService;
    this.shards = shards;
    syncTableAccess = new HashMap();
    tableSharding = new TableSpaceSharding(shards, key -> Math.abs(key.hashCode()) % shards.length);
    tableSharding.init().await();
    TableDescription[] schema = config.getSchema();
    return all(schema.length, i -> {
        Promise p = new Promise();
        tableSharding.createOrLoadTable(schema[i]).then((r, e) -> {
            if (r != null) {
                syncTableAccess.put(schema[i].getName(), r);
            }
            p.complete(r, e);
        });
        return p;
    });
