Each chart dimension gets its own page to store -consecutive values generated from the data collectors. Those pages comprise the **Page Cache**. - -When those pages fill up, they are slowly compressed and flushed to disk. It can -take `4096 / 4 = 1024 seconds = 17 minutes`, for a chart dimension that is being collected every 1 second, to fill a -page. Pages can be cut short when we stop Netdata or the DB engine instance so as to not lose the data. When we query -the DB engine for data we trigger disk read I/O requests that fill the Page Cache with the requested pages and -potentially evict cold (not recently used) -pages. - -When the disk quota is exceeded the oldest values are removed from the DB engine at real time, by automatically deleting -the oldest datafile and journalfile pair. Any corresponding pages residing in the Page Cache will also be invalidated -and removed. The DB engine logic will try to maintain between 10 and 20 file pairs at any point in time. - -The Database Engine uses direct I/O to avoid polluting the OS filesystem caches and does not generate excessive I/O -traffic so as to create the minimum possible interference with other applications. - -## Evaluation - -We have evaluated the performance of the `dbengine` API that the netdata daemon uses internally. This is **not** the web -API of netdata. Our benchmarks ran on a **single** `dbengine` instance, multiple of which can be running in a Netdata -parent node. We used a server with an AMD Ryzen Threadripper 2950X 16-Core Processor and 2 disk drives, a Seagate -Constellation ES.3 2TB magnetic HDD and a SAMSUNG MZQLB960HAJR-00007 960GB NAND Flash SSD. - -For our workload, we defined 32 charts with 128 metrics each, giving us a total of 4096 metrics. We defined 1 worker -thread per chart (32 threads) that generates new data points with a data generation interval of 1 second. The time axis -of the time-series is emulated and accelerated so that the worker threads can generate as many data points as possible -without delays. - -We also defined 32 worker threads that perform queries on random metrics with semi-random time ranges. The starting time -of the query is randomly selected between the beginning of the time-series and the time of the latest data point. The -ending time is randomly selected between 1 second and 1 hour after the starting time. The pseudo-random numbers are -generated with a uniform distribution. - -The data are written to the database at the same time as they are read from it. This is a concurrent read/write mixed -workload with a duration of 60 seconds. The faster `dbengine` runs, the bigger the dataset size becomes since more data -points will be generated. We set a page cache size of 64MiB for the two disk-bound scenarios. This way, the dataset size -of the metric data is much bigger than the RAM that is being used for caching so as to trigger I/O requests most of the -time. In our final scenario, we set the page cache size to 16 GiB. That way, the dataset fits in the page cache so as to -avoid all disk bottlenecks. - -The reported numbers are the following: - -| device | page cache | dataset | reads/sec | writes/sec | -|:------:|:----------:|--------:|----------:|-----------:| -| HDD | 64 MiB | 4.1 GiB | 813K | 18.0M | -| SSD | 64 MiB | 9.8 GiB | 1.7M | 43.0M | -| N/A | 16 GiB | 6.8 GiB | 118.2M | 30.2M | - -where "reads/sec" is the number of metric data points being read from the database via its API per second and -"writes/sec" is the number of metric data points being written to the database per second. - -Notice that the HDD numbers are pretty high and not much slower than the SSD numbers. This is thanks to the database -engine design being optimized for rotating media. In the database engine disk I/O requests are: -- asynchronous to mask the high I/O latency of HDDs. -- mostly large to reduce the amount of HDD seeking time. -- mostly sequential to reduce the amount of HDD seeking time. -- compressed to reduce the amount of required throughput. -As a result, the HDD is not thousands of times slower than the SSD, which is typical for other workloads. -An interesting observation to make is that the CPU-bound run (16 GiB page cache) generates fewer data than the SSD run -(6.8 GiB vs 9.8 GiB). The reason is that the 32 reader threads in the SSD scenario are more frequently blocked by I/O, -and generate a read load of 1.7M/sec, whereas in the CPU-bound scenario the read load is 70 times higher at 118M/sec. -Consequently, there is a significant degree of interference by the reader threads, that slow down the writer threads. -This is also possible because the interference effects are greater than the SSD impact on data generation throughput. diff --git a/database/engine/cache.c b/database/engine/cache.c index 4091684b..bc3ba6b6 100644 --- a/database/engine/cache.c +++ b/database/engine/cache.c @@ -1189,6 +1189,9 @@ premature_exit: } static PGC_PAGE *page_add(PGC *cache, PGC_ENTRY *entry, bool *added) { + internal_fatal(entry->start_time_s < 0 || entry->end_time_s < 0, + "DBENGINE CACHE: timestamps are negative"); + __atomic_add_fetch(&cache->stats.workers_add, 1, __ATOMIC_RELAXED); size_t partition = pgc_indexing_partition(cache, entry->metric_id); @@ -1199,6 +1202,12 @@ static PGC_PAGE *page_add(PGC *cache, PGC_ENTRY *entry, bool *added) { PGC_PAGE *page; size_t spins = 0; + if(unlikely(entry->start_time_s < 0)) + entry->start_time_s = 0; + + if(unlikely(entry->end_time_s < 0)) + entry->end_time_s = 0; + do { if(++spins > 1) __atomic_add_fetch(&cache->stats.insert_spins, 1, __ATOMIC_RELAXED); @@ -1755,7 +1764,7 @@ PGC *pgc_create(const char *name, cache->config.max_dirty_pages_per_call = max_dirty_pages_per_flush; cache->config.pgc_save_init_cb = pgc_save_init_cb; cache->config.pgc_save_dirty_cb = pgc_save_dirty_cb; - cache->config.max_pages_per_inline_eviction = (max_pages_per_inline_eviction < 2) ? 2 : max_pages_per_inline_eviction; + cache->config.max_pages_per_inline_eviction = max_pages_per_inline_eviction; cache->config.max_skip_pages_per_inline_eviction = (max_skip_pages_per_inline_eviction < 2) ? 2 : max_skip_pages_per_inline_eviction; cache->config.max_flushes_inline = (max_flushes_inline < 1) ? 1 : max_flushes_inline; cache->config.partitions = partitions < 1 ?
