CLI entry point for continuous live replication.

Run with:

clj -X:replicate \
  :source-client-config '{:server-type :cloud :region "us-east-1" :system "prod" :endpoint "https://..."}' \
  :source-db-name '"my-database"' \
  :target-client-config '{:server-type :cloud :region "us-west-2" :system "dr" :endpoint "https://..."}' \
  :target-db-name '"my-database-replica"'

continuous-replicate clj

(continuous-replicate {:keys [source-client-config source-db-name
                              target-client-config target-db-name segment-size

                              max-retry-delay-ms log-level blacklist verify?]
                       :or {segment-size 1000
                            poll-interval-ms 5000
                            prefetch-buffer 5
                            max-retry-delay-ms 300000
                            log-level :info
                            blacklist #{}
                            verify? true}})

Entry point for clj -X. Runs continuous live replication from source to target database.

Required parameters:

• :source-client-config - Map for d/client (source Datomic system)
• :source-db-name - Database name on source (string)
• :target-client-config - Map for d/client (target Datomic system)
• :target-db-name - Database name on target (string)

Optional parameters:

• :segment-size - Transactions per segment (default 1000)
• :poll-interval-ms - Polling interval when idle (default 5000)
• :prefetch-buffer - Pre-fetch buffer size (default 5)
• :max-retry-delay-ms - Maximum backoff delay on errors (default 300000)
• :log-level - Timbre log level keyword (default :info)
• :blacklist - Set of attribute keywords to exclude from restore
• :verify? - Enable ID verification (default true)

Example:

clj -X:replicate \
  :source-client-config '{:server-type :cloud :region "us-east-1" :system "prod" :endpoint "https://..."}' \
  :source-db-name '"production-db"' \
  :target-client-config '{:server-type :cloud :region "us-west-2" :system "backup" :endpoint "https://..."}' \
  :target-db-name '"production-db-replica"' \
  :segment-size 1000 \
  :poll-interval-ms 5000

The replication will:

1. Connect to source and target databases
2. Create target database if it doesn't exist
3. Start continuous restore from source to target
4. Run until interrupted (SIGTERM/SIGINT)
