Top Ten Time Series DBs
- bglusman 9y agoI submitted this mostly hoping to see if there were already any comments on it, but I guess maybe now there will be if anyone has thoughts! I'd never heard of Dalmatiner before, and they admit bias because authors maintain, but they seem somewhat balanced in that I notice their spreadsheet here[1] acknowledges a fair number of advantages InfluxDB has over them.

- Licenser 9y agoI helped to create that spreadsheet we tried to be as fair as possible and whenever possible link reproducible, verifiable benchmarks (but then again all benchmarks are lies ;).

- sceadu 9y agoIt may also be worthwhile to take a look at the CMU Time Series Database lecture series: https://www.youtube.com/watch?v=2SUBRE6wGiA&list=PLSE8ODhjZXjY0GMWN4X8FIkYNfiu8_Wl9 https://www.youtube.com/watch?v=2SUBRE6wGiA&list=PLSE8ODhjZX...
- jordan_ 9y agoI would also suggest checking out Timescale (http://www.timescale.com/ http://www.timescale.com/) - It's a extension for postgres and does a phenomenal job
- vthriller 9y ago> Could you do it all in MySQL or Postgres? Possibly, but you'd have to write a lot of code to add the functionality many of these databases already provide. Or you can throw in something like [0], I guess. (This thing is still in my todo list though, so I can't tell anything beside the fact that this thing also exists.)

- manigandham 9y agoAny distributed relational database, especially with compressed columnstores, will be better than any existing timeseries specific database. Timescale, Citus, PipelineDB = postgres based but no columnstores. MemSQL, MariaDB, ClickHouse = with columnstores.
- saosebastiao 9y agoTime series databases have many many uses, not all of which require or even benefit from column stores. Some uses may even be hurt by column stores.
- manigandham 9y agoLike what? All those use cases are easily covered and better done by scalable relational systems. Time series is just a narrow subset application.
- saosebastiao 9y agoTime series is not even close to a narrow subset. There are tons of relevant use cases for time series databases that conflict with the cost/benefit positioning of column storage. What is someone to do if they need moving window queries (thereby requiring a ts db), but also have to deal with heavy mvcc transactions, lots of updates, weakly ordered inserts? These aren’t uncommon conditions to deal with, even in time series data. Examples: * Event sourcing collects events but also often has a notion of a “current” record, meaning inserting a new event requires updating a previous event to invalidate it. * Financial transactions may involve many append-only tables, but which are linked with data in heavily updated tables, often requiring transactional mvcc. * Logging events asynchronously or across several nodes often produces events that are emitted out of order which can sometimes span several time partitions, making insertion costly for column stores.

- jwatte 9y agoWe ran into performance problems with graphite that github.com/imvu-open/istatd doesn't have. I'd much rather run the latter for production and application monitoring! It has, like, 10x the per machine performance of the others. (See also: COST)
- kalmar 9y agoHonest question: how do people use influxdb for monitoring and alerting? Our metrics feed into influx, and I cannot get answers to simple questions like “what is the failure rate” because arithmetic across measurements isn't possible [0]. I could shoehorn things into a schema to make it work, but in the limit I end up with one mega measurement.

- zaarn 9y agoI've had similar problems. I feed analytics from my webpage into InfluxDB and it is impossible to compute a histogram of pageload times of the last 10k hits.
- agnivade 9y agoRight. You would have to approximate the last 10k hits to the time period. Also, check out the grafana histogram plugin. Works great for these scenarios.
- zaarn 9y agoI've tried the grafana histogram plugin but it doesn't work; simply get a 404 error on load and makes the entire row unusuable.
- agnivade 9y ago> Honest question: how do people use influxdb for monitoring and alerting? In our case, influx+grafana+alert notifications work well. Yes, the query language needs a lot of work. It doesn't support anything beyond simple queries.
- aequitas 9y agoMaybe try to use Graphite as additional query API for influx. We switched to Influx from Graphite but some queries where unable or cumbersome to translate into Influx query language (especially inside Grafana). In our case we use Graphite-api with a Influx plugin instead of Graphite's own frontend. https://github.com/InfluxGraph/influxgraph https://github.com/InfluxGraph/influxgraph

- mattb314 9y agoI'm a little confused about the columnar database comment: > Performing queries across billions of metrics looking for labels that only match a few of them (a common scenario with time series data at scale) is really slow in Cassandra. This is because of the way it stores data in columns. This extends to any columnar database including Google's BigQuery which all have a natural disadvantage with time series data. I've pretty much only heard "columnar database" used as opposed to row store database, and it seems like storing time series data in columns makes much more sense. Could someone clear up exactly how "labels" (which I probably don't understand) are so much harder for column stores to deal with?
- Licenser 9y agoBecause labels or dimensions are not stored in as a value but as a row identifier in most implementations. That results in having to scan the entire row space and look at every row name and see if it matches the lookup. Storing labels in a row based system (like SQL) allows querying by value, not column name which takes advantage of all optimizations and indexes making it a lot faster. That said there is nothing forbidding someone to do both, DalmatinerDB, for example, uses a column-based format for metric values but a row-based format (PostgreSQL) for dimensions.
- manigandham 9y agoCassandra is a wide-column or column-family database, which I just refer to as advanced or nested key/value. Unfortunately it's commonly mixed up with column-oriented or columnar tables and database. https://en.wikipedia.org/wiki/Column_family https://en.wikipedia.org/wiki/Column_family
- leetbulb 9y agoMentioned on this list, Druid is #1 is my book. Imply[0] has a very nice system built around Druid. [0] https://imply.io/ https://imply.io/
- mikepurvis 9y agoI'd be interested to see more commentary on the graphical front end side of things. I loathe how slow and overcomplicated Kibana is, but it does provide a very nice kickstart to the business of exploring data and pulling together dashboards— if, of course, you're using Elastic. My killer tool for this would be able to talk to PostgreSQL, have a charting backend based on Canvas/WebGL (so able to handle thousands of points rather than dozens), and be easily pluggable to add in new kinds of visualizations.
- azylman 9y agoHave you seen Grafana? I've had very good experiences with it. I've never used it with Postgres, but it supports it: http://docs.grafana.org/features/datasources/postgres/ http://docs.grafana.org/features/datasources/postgres/
- deepsun 9y agoNo ClickHouse, no PipelineDB?
- Gepsens 9y agoOf course author would compare apples and oranges. Druid is a Time series oriented bucketed OLAP database, not a two dimensional metrics db like dalmatiner or influx. While I like all of these databases they don't cover the same spaces. This blog post is useless
- jmcgough 9y agoThis seems more like an ad for DalmatinerDB. It's just weird to come up with a ranking and then (of course) give your DB first place. It does seem like an interesting tsdb though, love that it's built on riak.
- Licenser 9y agoOutlyr has not build DalmatinerDB they've used it and contributed a bit to it.
- frik 9y agoPlease add also relational databases incl MySQL and Postgres (both work great for time series) and Cassandra itself. While also kairosdb, heroic, blueblood, hawkula are based on Cassandra, it can be used for time series as well.
- gaius 9y agoA comparison of timeseries DBs without KDB? I call shenanigans. Also others have mentioned Timescale. This article is pure clickbait from someone who isn't a serious practitioner in the field.
- SifJar 9y ago> I set some rules to attempt to limit the scope, otherwise this blog post would never end. > Only free and open source time series databases and their features have been compared. Therefore if someone asks “have you tried Kdb+ or Informix?” the answer will be no. They are probably awesome though. would be nice to see how KDB compares though
- gaius 9y ago32-bit KDB is free
- pritambaral 9y agoFree as in beer though, not speech; which is what the author intended, I believe.
- SifJar 9y agofree, but not open source. author specified both as criteria
- Redoubts 9y agoAre any of these embeddable like SQLite?
