System Requirements

Network Flexibility

Firehose is extremely elastic and can support networks of varied sizes and shapes.

Ensure to gain a solid understanding of the different data stores, artifacts, and databases required for operation.

Deployment efforts will match the size of history, and the density of the blockchain being consumed.

Network shapes

Requirements for different shapes of networks are as follows.

Persistent chains

In order to scale easily, components that run in a single process need to be decoupled.

The storage requirements will vary depending on the following metrics.

  • History length - The status of whether or not all the blocks are serving through Firehose.

  • Throughput in transactions and calls - Calls on Ethereum are the smallest units of execution to produce meaningful data, transaction overhead becomes negligible once you have two or three calls in a transaction. A simple ERC20 transfer generally has one call, or two calls when there is a proxy contract involved. Uniswap swap transactions, for instance, are usually composed of a few dozen of calls.

Limiting Factors

The CPU/RAM requirements will depend on these factors:

  • High Availability - Highly available deployments will require two, or more times the resources listed in the following examples, as a general rule.

  • Throughput of queries - Firehose is built for horizontal scalability. As the need for requests per second increase the deployment increases in size and more CPU/RAM is required in the deployment cluster.

Instrumented Chain's Native Binary

Firehose requires native instrumentation of the binary of the chain you want to sync with, a vanilla binary of the chain without Firehose support built in it is not going to work. So you can only today synchronize with Firehose enabled chains.

Other blockchains beyond the ones currently supported can be used with Firehose through the process of instrumentation. Information is provided for the instrumentation process of new blockchains
