## Wormhole event BigTable schema
|
||
|
|
|
||
|
|
### Row Keys
|
||
|
|
|
||
|
|
Row keys contain the MessageID, delimited by colons, like so: `EmitterChain:EmitterAddress:Sequence`.
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
### Column Qualifiers
|
||
|
|
|
||
|
|
Each column qualifier below is prefixed with its column family.
|
||
|
|
|
||
|
|
- `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.
|
||
|
|
|
||
|
|
- `QuorumState:SignedVAA` the VAA with the signatures that contributed to quorum.
