Aggregate Collection

Collections is an analytics API (not real-time, though it may look like one).
Not all filters and sortings are working now. Data is provided only for the past 7 days.

When you may need aggregate of collections?

If you want to apply some aggregators like COUNT, MAX, MIN, SUM, AVERAGE on some blockchain data.


const aggregationFunctionsResults = result =
collection: 'accounts',
fields: [
field: "balance",
fn: "MIN"
field: "balance",
fn: "MAX"
}, {
field: "balance",
}, {
field: "balance",
fn: "SUM"
field: "balance",
fn: "COUNT"
console.log("Minimum account balance: " + aggregationFunctionsResults[0]);
console.log("Maximum account balance: " + aggregationFunctionsResults[1]);
console.log("Average balance: " + aggregationFunctionsResults[2]);
console.log("Total balance of all accounts: " + aggregationFunctionsResults[3]);
console.log("Number of accounts: " + aggregationFunctionsResults[4] + '\n');

About collections

There are a few collections with blockchain data:
  • accounts: blockchain account data;
  • transactions: transactions related to accounts;
  • messages: input and output messages related to transactions;
  • blocks: blockchain blocks.
  • block_signatures : validator block signatures
