        Database sync per bytes for transactional mode. This parameter will impact the sync frequency of database after batch push. For BDB-JE transactional mode, it won't matter since BDB-JE will persist every update in the database right away; For RocksDB transactional mode, it will impact the flush frequency of memtable to SST file, and normally we would like to have this config to be comparable to the memtable size; Negative value will disable this threshold.

For BDB-JE deferred-write mode, it will impact the sync frequency, but BDB-JE will do auto-flush if the memory is full; For RocksDB deferred-write mode, it will decide the file size of each SST file since every sync invocation will generate a new SST file; Negative value will disable this threshold.

      • SERVER_PARTITION_GRACEFUL_DROP_DELAY_IN_SECONDS

        public static final java.lang.String SERVER_PARTITION_GRACEFUL_DROP_DELAY_IN_SECONDS
        When load balance happens, a replica could be moved to another storage node. When dropping the existing replica through Helix state transition: 'ONLINE' -> 'OFFLINE' and 'OFFLINE' -> 'DROPPED', a race condition could happen since Router in-memory partition assignment update through Zookeeper is independent from database drop in storage node, so Router could possibly forward the request to the storage node, which has just dropped the partition. To mitigate this issue, we will add a delay in state transition: 'OFFLINE' -> 'DROPPED' to drain all the incoming requests to the to-drop partition, and we will enable error-retry on Router as well.

        public static final java.lang.String SERVER_LEAKED_RESOURCE_CLEAN_UP_INTERVAL_IN_MINUTES
        When a BDB partition is dropped, the disk space is not released immediately; a checkpoint is needed to release the disk space; so a cleaner thread is spawned for the entire storage service; the cleaner thread will wake up every few hours and check whether it needs to do a checkpoint; if so, clean up each store sequentially.

        public static final java.lang.String SERVER_KAFKA_MAX_POLL_RECORDS
        This config is used to control the maximum records returned by every poll request. So far, Store Ingestion is throttling per poll, so if the configured value is too big, the throttling could be inaccurate and it may impact GC as well.

        public static final java.lang.String SERVER_DISK_HEALTH_CHECK_TIMEOUT_IN_SECONDS
        When there is an actual disk failure, health check operation would hang, so this config decides how fast the servers will start reporting unhealthy after the health check stop updating status; however, in order to reduce the possibility of false alerts (for example, the health check updates can be delayed by GC), we couldn't set the timeout too small. Currently by default, the timeout is 30 seconds.

        This config is used to control how much time we should wait before cleaning up the corresponding ingestion task when an non-existing topic is discovered. The reason to introduce this config is that `consumer#listTopics` could only guarantee eventual consistency, so `consumer#listTopics` not returning the topic doesn't mean the topic doesn't exist in Kafka. If `consumer#listTopics` still doesn't return the topic after the configured delay, Venice SN will unsubscribe the topic, and fail the corresponding ingestion job.

        After this amount of time, DDS Router will retry once for the slow storage node request. The configured format will be like this way: "1-10:20,11-50:50,51-200:80,201-:1000" Let me explain the config by taking one example: If the request key count for a batch-get request is '32', and it fails into this key range: [11-50], so the retry threshold for this batch-get request is 50ms. That is a limitation here: The retry threshold is actually for each scatter-gather request, but this config is not strictly with the actual key count inside each scatter-gather request, which means even if there is only one key in a scatter-gather request with the above example, Router will wait for 50ms to retry this scatter-gather request. For now, it is not big issue since for now we mostly want to use this config to skip the storage node, which is experiencing long GC pause. So coarse-grained config should be good enough.

      • ROUTER_SMART_LONG_TAIL_RETRY_ENABLED

        public static final java.lang.String ROUTER_SMART_LONG_TAIL_RETRY_ENABLED
        Whether to enable smart long tail retry logic, and this logic is only useful for batch-get retry currently. This feature is used to avoid the unnecessary retries in the following scenarios: 1. Router is suffering long GC pause, no matter whether Storage Node is fast or not; 2. The retried Storage Node is slow according to the original request; For case 1, unnecessary retries will make Router GC behavior even worse; For case 2, unnecessary retries to the slow Storage Node will make the slow Storage Node even slower, and the overall latency won't be improved; For case 1, here is how smart retry works: 1. When the delay between the retry request and the original request is over ROUTER_LONG_TAIL_RETRY_FOR_BATCH_GET_THRESHOLD_MS + ROUTER_SMART_LONG_TAIL_RETRY_ABORT_THRESHOLD_MS, smart retry logic will treat the current Router to be in bad state (long GC pause or too busy), the retry request will be aborted; 2.ROUTER_SMART_LONG_TAIL_RETRY_ABORT_THRESHOLD_MS is the way to measure whether Router is in good state or not, and need to be tuned in prod; For case 2, the retry request will be aborted if the original request to the same storage node hasn't returned, and the slowness measurement is inside one request when scatter-gathering.

        public static final java.lang.String ROUTER_LONG_TAIL_RETRY_MAX_ROUTE_FOR_MULTI_KEYS_REQ
        This config is used to limit the maximum retries in route unit. In large batch-get/compute cluster, when enabling long-tail retry, in the worst scenarios, Router could trigger a retry storm since each route could retry independently. This config is used to specify the maximum retry in route unit. If the configured value is 1, it means the current request will at most one route. This could mitigate the latency issue in most of the case since the chance to have multiple slow storage nodes is low, also even with unlimited retries, it won't help since multiple replicas for the same partition are in a degraded state.

        This is the minimum number of Kafka topics that are guaranteed to be preserved by the leaky topic clean up routine. The topics with the highest version numbers will be favored by this preservative behavior. All other topics (i.e.: those with smaller version numbers) which Venice does not otherwise know about from its metadata will be considered leaked resources and thus be eligible for clean up. A value greater than zero is recommended for Storage Node to not run into UNKNOWN_TOPIC_OR_PARTITION issues N.B.: A known limitation of this preservation setting is that during store deletion, if a topic has been leaked recently due to an aborted push, then there is an edge case where that topic may leak forever. This leak does not happen if the latest store-versions are successful pushes, rather than failed ones. Furthermore, if a store with the same name is ever re-created, then the clean up routine would resume and clean up the older leaky topics successfully. This edge case is deemed a small enough concern for now, though it could be addressed with a more significant redesign of the replication pipeline.

Old state clearing is disabled if this config is set to -1.
