Architecture

Firehose for Injective uses an RPC poller approach. The poller fetches blocks from Injective RPC endpoints and converts them to Firehose format.

Reader Node Configuration

Injective Mainnet

firecore start reader-node <apps> \
  --advertise-chain-name="injective-mainnet" \
  --common-first-streamable-block=<start-block> \
  --reader-node-path="fireinjective" \
  --reader-node-arguments="fetch rpc {first-streamable-block} --state-dir={node-data-dir}/poller/states --block-fetch-batch-size=4 --endpoints=<rpc-endpoint>" \
  <other_flags...>

Injective Testnet

firecore start reader-node <apps> \
  --reader-node-path="fireinjective" \
  --reader-node-arguments="fetch rpc {first-streamable-block} --state-dir={node-data-dir}/poller/states --block-fetch-batch-size=1 --endpoints=<rpc-endpoint>" \
  --common-first-streamable-block=<start-block> \
  --advertise-chain-name="injective-testnet" \
  <other_flags...>

Key Poller Flags

Flag	Description
fetch rpc	Subcommand to run the RPC poller
{first-streamable-block}	Variable substituted from --common-first-streamable-block
--state-dir	Directory to store poller state
--block-fetch-batch-size	Number of blocks to fetch in parallel
--endpoints	Injective RPC endpoint URL(s), can be specified multiple times
