我在Aerospike(v3.5.12)中用作一个节点的内存键值存储。
还使用Java客户端(v3.1.7)来检索和写入数据。
我注意到在某些QPS(3K)读取(批处理)和写入。
有些数据检索无效。
[INFO] [24/11/2015 14:43:38.782] Write Data
[ERROR] [24/11/2015 14:43:38.937] Read Data - Not Found
有人遇到类似问题吗?
更新
我更新了Aerospike 3.7.1。
我在以下问题中使用异步操作:
public void store() {
WritePolicy expirationWritePolicy = new WritePolicy();
expirationWritePolicy.sendKey = true;
expirationWritePolicy.priority = Priority.HIGH;
expirationWritePolicy.expiration = 10;
Key key = new Key(namespace, SET_NAME, requestId);
Bin bin = new Bin(BIN_NAME, serializer.toBinary(budgetCommit));
Bin extra = new Bin("extra", "data");
client.put(expirationWritePolicy, new WriteListener() {
@Override
public void onSuccess(Key key) {
logger.info("Succeed to store {}", requestId());
}
@Override
public void onFailure(AerospikeException exception) {
logger.error(exception, "Fail to store {}", key);
}
}, key, extra, bin);
}
public void retrieve() {
WritePolicy defaultWritePolicy = new WritePolicy();
defaultWritePolicy.priority = Priority.LOW;
defaultWritePolicy.sendKey = true;
Key key = new Key(namespace, SET_NAME, requestId);
Bin closeExtra = new Bin("extra", "_closed");
client.operate(defaultWritePolicy, new RecordListener() {
@Override
public void onSuccess(Key key, Record record) {
if (record.getValue(BIN_NAME) == null){
logger.error("Fail to retrieve {}", requestId);
}
}
@Override
public void onFailure(AerospikeException exception) {
logger.error("Fail to retrieve {} : {}", requestId, exception.getMessage());
}
}, key,
Operation.append(closeExtra), Operation.get());
}

当Aerospike有Ack时,会调用onSuccess回调。
在主写入时开始失败大约8k QPS。
答案 0 :(得分:3)
可能会发生重新平衡轮次。批处理进入该版本不会代理到其他节点。
Aerospike Server 3.6.4有一个可以代理的新批处理实现。
