Example 10 with Entry

use of com.alibaba.otter.canal.protocol.CanalEntry.Entry in project canal by alibaba.

the class CanalServerWithEmbedded method getWithoutAck.

/**
     * 不指定 position 获取事件。canal 会记住此 client 最新的 position。 <br/>
     * 如果是第一次 fetch，则会从 canal 中保存的最老一条数据开始输出。
     * 
     * <pre>
     * 几种case:
     * a. 如果timeout为null，则采用tryGet方式，即时获取
     * b. 如果timeout不为null
     *    1. timeout为0，则采用get阻塞方式，获取数据，不设置超时，直到有足够的batchSize数据才返回
     *    2. timeout不为0，则采用get+timeout方式，获取数据，超时还没有batchSize足够的数据，有多少返回多少
     *    
     * 注意： meta获取和数据的获取需要保证顺序性，优先拿到meta的，一定也会是优先拿到数据，所以需要加同步. (不能出现先拿到meta，拿到第二批数据，这样就会导致数据顺序性出现问题)
