Naming Conventions
StreamingFast Firehose naming conventions
Each Firehose setup has unique naming conventions depending on versioning and the blockchain being targeted.
Note: This page serves as a resource to provide a unified experience for developers working between the Firehose versions.
Each Firehose setup uses two forms of naming. The naming is taken from the target blockchain's protocol name. The two forms establish a long and a short form of the protocol name.
The short form will be the shortest abbreviation of the chain name possible. For Ethereum, the long form would be
ethereum and the short form would be eth.Important: These naming forms will be referenced throughout the Firehose naming conventions documentation.
For line-based Firehose instrumentations, each line of output should start with the word
FIRE followed by a simple word defining what data to expect on each line.Code used for instrumentation within the native node should be bundled together using
firehose as the name of the module/crate/package is preferable.Important: The top-level flag
--firehose-enabled can be used for quickly dumping massive quantities of data to standard output from Firehose.Replace
acme with the chain you are instrumenting for the following items.In a sample scenario instrumenting the Tezos blockchain acme would be replaced by the two forms of Tezos; something similar to
tezos and tez.If the target blockchain were Tezos the name would be
firehose-tezos.The binary name will be the first half of the Firehose product name "fire" combined with the short form of the target blockchain. If the target blockchain were Tezos, the name of the binary would be something similar to
firetez.The top-level Block protobuf definition convention for a new chain is
sf.[chain].type.v1.Block.
\ For Tezos it would be sf.tezos.type.v1.BlockProto Directory -
/protoThe proto directory contains properly namespaced protobuf definitions for the target chain.
For example
proto/sf/acme/type/v1/type.proto as the first, and often only, file.
For Tezos it would be proto/sf/tezos/type/v1/type.proto\Types Directory -
/typesThe types directory contains rendered protobuf types and some helpers.
For example:
/types/pb/sf/acme/type/v1;pbacme, using the short form package name prefixed with pb.
For Tezos it would be something similar to:
/types/pb/sf/acme/type/v1;pbtezos\/types/go.mod: to be able to import github.com/streamingfast/firehose-acme/types and pull only a limited number of dependencies.Codec Directory -
/codecThe
codec directory contains all of the coding and decoding methods used to manipulate the stream of data coming from the Firehose-enabled Blockchain Node. Note, t_his library is concerned only with the data wrangling, and not the management of nodes._Last modified 3mo ago
