Wormhole event BigTable schema

Row Keys

Row keys contain the MessageID, delimited by colons, like so: EmitterChain:EmitterAddress:Sequence.

  • EmitterAddress left padded with 0s to 32 bytes, then hex encoded.

  • Sequence left padded with 0s to 16 characters, so rows are ordered in the sequence they occured. BigTable Rows are sorted lexicographically by row key.

BigTable can only be queried for data in the row key. Only row key data is indexed. You cannot query based on the value of a column; however you may filter based on column value.

Column Families

BigTable requires that columns are within a "Column family". Families group columns that store related data. Grouping columns is useful for efficient reads, as you may specify which families you want returned.

The column families listed below represent data unique to a phase of the attestation lifecycle.

  • MessagePublication holds data about a user's interaction with a Wormhole contract. Contains data from the Guardian's VAA struct.

  • QuorumState stores the signed VAA once quorum is reached.

  • TokenTransferPayload stores the decoded payload of transfer messages.

  • AssetMetaPayload stores the decoded payload of asset metadata messages.

  • NFTTransferPayload stores the decoded payload of NFT transfer messages.

  • TokenTransferDetails stores information about the transfer.

  • ChainDetails stores chain-native data supplimented from external source(s).

Column Qualifiers

Each column qualifier below is prefixed with its column family.

MessagePublication

  • MessagePublication:Version Version of the VAA schema.
  • MessagePublication:GuardianSetIndex The index of the active Guardian set.
  • MessagePublication:Timestamp Timestamp when the VAA was created by the Guardian.
  • MessagePublication:Nonce Nonce of the user's transaction.
  • MessagePublication:Sequence Sequence from the interaction with the Wormhole contract.
  • MessagePublication:EmitterChain The chain the message was emitted on.
  • MessagePublication:EmitterAddress The address of the contract that emitted the message.
  • MessagePublication:InitiatingTxID The transaction identifier of the user's interaction with the contract.
  • MessagePublication:Payload The payload of the user's message.
