Problem

When looking at these types:

graph-tooling/packages/ts/chain/ethereum.ts

Lines 626 to 627 in 4b4ad3e

	public logIndex: BigInt,
	public transactionLogIndex: BigInt,

It's not obvious that the logIndex is the index of the event in the entire block, whereas transactionLogIndex is the index of the event in the transaction.

Confused Users

• What is the `index` field in the `Transaction` type provided by The Graph? #2035

Solution

• Rename Event.logIndex to Event.blockLogIndex.
• For backward-compatibility, maintain Event.logIndex, but annotate it as deprecated.
