Firehose chart spec

[calinah]

Simple setup (non-HA)
Firehose single binary that does :

• reader - will spun geth by itself (polygon as target to read data):
• merger - merge blocks into chunks (reader outputs 1 block at the time - merge block gets rid of duplicates). Every merge block in Ethereum has 100 blocks
• relayer -
• firehose - does substreams calculations. Tier 1 firehose config is the main config, tier 2 config is needed for running substreams.

Storage:
*1st version store on local filesystem

• GCS or S3
• ext4 might not work that well

If blocks are missing rewind.

Firehose HA
Firehose single binary that does :

• 2 reader - will spun geth by itself (polygon as target to read data):
• 1 merger - merge blocks into chunks (reader outputs 1 block at the time - merge block gets rid of duplicates). Every merge block in Ethereum has 100 blocks
• 2 relayer -
• 2 or more replicas firehose - based on number of users and subgraphs (1000 subgraphs per firehose)

Storage:

• Object storage or shared filesystem or both
