# Scenarios: Backfill topic indexes - 1, Backfill topic indexes - 2, Backfill topic indexes - 3
|
|
#
|
|
# The topic backfill utility builds topicSummaries and topicRecency from the
|
|
# existing rooms store so the read side can serve /topics by recency without
|
|
# scanning posts. Rooms with posts get postCount and lastHeight; follow-only
|
|
# rooms get postCount 0 and lastHeight 0. Running the backfill twice is
|
|
# idempotent.
|
|
#
|
|
# Fixture "rooms-with-topics-and-follows":
|
|
# rooms store:
|
|
# bitcoin:post-100 { room: bitcoin, txid: post-100, type: post, blockHeight: 600100 }
|
|
# bitcoin:post-200 { room: bitcoin, txid: post-200, type: post, blockHeight: 600200 }
|
|
# bitcoin:addr-f { room: bitcoin, addr: addr-f, type: follow, unfollow: false }
|
|
# cash:post-250 { room: cash, txid: post-250, type: post, blockHeight: 600250 }
|
|
# lone:addr-f { room: lone, addr: addr-f, type: follow, unfollow: false }

Feature: Backfill topic indexes
|
|
|
|
Background:
|
|
Given a psf-memo-db instance with rooms, topicSummaries, and topicRecency stores
|
|
Given the fixture "rooms-with-topics-and-follows" is loaded into the rooms store
|
|
|
|
Scenario Outline: Backfill topic indexes - 1 backfill summarizes every room
|
|
When the topic backfill utility is run
|
|
Then the topicSummaries store contains the room "<room>" with postCount <postCount> and lastHeight <height>
|
|
|
|
Examples:
|
|
| room | postCount | height |
|
|
| bitcoin | 2 | 600200 |
|
|
| cash | 1 | 600250 |
|
|
| lone | 0 | 0 |
|
|
|
|
Scenario Outline: Backfill topic indexes - 2 backfill builds the recency index
|
|
When the topic backfill utility is run
|
|
Then the topicRecency store records the room "<room>" at block height <height>
|
|
|
|
Examples:
|
|
| room | height |
|
|
| bitcoin | 600200 |
|
|
| cash | 600250 |
|
|
| lone | 0 |
|
|
|
|
Scenario Outline: Backfill topic indexes - 3 backfill is idempotent
|
|
When the topic backfill utility is run
|
|
And the topic backfill utility is run again
|
|
Then the topicSummaries store contains the room "<room>" with postCount <postCount> and lastHeight <height>
|
|
And the topicRecency store records the room "<room>" at block height <height>
|
|
|
|
Examples:
|
|
| room | postCount | height |
|
|
| bitcoin | 2 | 600200 |
|
|
| cash | 1 | 600250 |
