Example 1 with AllJobFinishedListener

use of io.mycat.sqlengine.AllJobFinishedListener in project Mycat-Server by MyCATApache.

the class ShareRowOutPutDataHandler method processSQL.

public void processSQL(String sql, EngineCtx ctx) {
    String ssql = joinParser.getSql();
    getRoute(ssql);
    RouteResultsetNode[] nodes = rrs.getNodes();
    if (nodes == null || nodes.length == 0 || nodes[0].getName() == null || nodes[0].getName().equals("")) {
        ctx.getSession().getSource().writeErrMessage(ErrorCode.ER_NO_DB_ERROR, "No dataNode found ,please check tables defined in schema:" + ctx.getSession().getSource().getSchema());
        return;
    }
    this.ctx = ctx;
    String[] dataNodes = getDataNodes();
    maxjob = dataNodes.length;
    ShareDBJoinHandler joinHandler = new ShareDBJoinHandler(this, joinParser.getJoinLkey());
    ctx.executeNativeSQLSequnceJob(dataNodes, ssql, joinHandler);
    EngineCtx.LOGGER.info("Catlet exec:" + getDataNode(getDataNodes()) + " sql:" + ssql);
    ctx.setAllJobFinishedListener(new AllJobFinishedListener() {
