Elasticsearch is more efficient when used with storage tiering, which decreases the total cost of ownership for Elasticsearch, plus you get the added benefits of writing data to MinIO that is immutable, versioned and protected by erasure coding. MinIO is frequently used to store Elasticsearch snapshots and if you use MinIO to store your Elasticsearch frozen tier, you can use the same MinIO API you already know and love to search these snapshots. But as the data gets older, it becomes less useful for immediate troubleshooting and doesn’t need to be searched as quickly as the rest.Īs a DevOps engineer, you might tier off your data as follows: Generally data from the last few weeks is probably the most searched by folks in the organization so that is stored on the fastest hardware. However, storing 2 years worth of searchable data on fast storage (such as NVMe) can take up a lot of costly drive space. If you have a service that misbehaves seemingly at random, you would want to go back as far as possible to identify a pattern and uncover the cause. By examining historical data, you will be able to see trends, find patterns and act accordingly. As a DevOps engineer, one of the most important things at your disposal is the amount of logs and metrics you have on hand for correlation purposes. The short answer is that we deploy Elasticsearch to help us troubleshoot systems, so we need to design systems that mirror our workflow and enable rapid diagnosis and correction. Why is it important to design your Elasticsearch deployment to around multiple tiers? Why not have a single tier and keep adding new and removing old data? Once data is stored in the MinIO object store, you can use ElasticSearch Mount API to partially mount the frozen tier data to make it searchable. All the data in this tier is completely stored in an object store such as MinIO. The frozen tier differs from the other three tiers because it doesn’t store any data locally. Besides the above tiers, ElasticSearch also supports the frozen tier. What is common between Hot, Warm and Cold tiers is that there is at least one local copy of the data on each of these configurations. Cold storage is generally local storage used to house single replicas where data doesn’t need to be accessed as often, which conserves storage capacity by avoiding storing multiple copies of the same file. Warm tier is used for cost conscious data where speed and performance are sacrificed a little and the data is put on slower hardware, perhaps HDD. Hot tier holds data that is actively used and is the latest and greatest data available at high speed, perhaps from NVMe. In order to balance performance, capacity and cost, ElasticSearch has historically supported several types of tiers: Hot, Warm and Cold.
