Configuration

Glasnost now requires a PostgreSQL database.

You need to configure the following Postgres database parameters using the Docker ENV variables:

• GLASNOST_DB
• GLASNOST_DB_HOST
• GLASNOST_DB_PORT
• GLASNOST_DB_USERNAME
• GLASNOST_DB_PASSWORD

Other parameters, such as PORT, STEEM_URL and GOLOS_URL, can be configured in the Docker file.

Changelog

• golos_blocks and steem_blocks tables, indexes and schemas were added
• blockchain synchronization subsystem and events handling has been improved and now handles block events
• sync speed and perfomance was improved
• various minor improvements and bugfixes
• updated docker image

Examples of GraphQL queries

{
  comments(blockchain:"steem", author: "ontofractal", isPost: true, category: "steemdev"){
    id,
    title,
    author,
    permlink,
    parentAuthor,
    parentPermlink,
    body
    tags,
    category,
    created,
    totalPayoutValue,
    pendingPayoutValue
  }
}

{
  comment(blockchain:"steem", author: "ontofractal", permlink: "glasnost-v0-12-released-now-with-postgresql-realtime-and-7-day-lookback-comments-data-sync-open-source-app-server-for-steem"){
