Example	Description	Topics
extrinsic-finalized-block (opens new window)	Indexes extrinsics so they can be queried by their hash	The simplest example with a block handler function
block-timestamp (opens new window)	Indexes timestamp of each finalized block	Another simple call handler function
validator-threshold (opens new window)	Indexes the least staking amount required for a validator to be elected.	More complicated block handler function that makes external calls to the @polkadot/api for additional on-chain data

entity-relation (opens new window)	Indexes balance transfers between accounts, also indexes utility batchAll to find out the content of the extrinsic calls	One-to-many and many-to-many relationships and complicated extrinsic handling
kitty (opens new window)	Indexes birth info of kitties.	Complex call handlers and event handlers, with data indexed from a custom chain
