Evaluation checklist
Questions to ask in any Qlik Replicate evaluation
Here is how TwinCommit answers each one. Put the same questions to every vendor on your shortlist.
| Question | TwinCommit |
|---|---|
| What has to be installed or enabled inside the source database? | ✓Nothing beyond standard logging settings. No triggers, capture tables, shadow tables or stored procedures. |
| How is exactly-once delivery guaranteed after a crash? | ✓The checkpoint is committed in the same target transaction as the data, so a restart never loses or repeats a transaction. |
| Are transactions applied in source commit order? | ✓Yes. Changes are buffered per transaction and applied at commit, in commit order. Rolled-back work never reaches the target. |
| What runs on the replication host? | ✓One static binary. No JVM, no application server, no separate manager process. |
| Does one product cover relational, NoSQL, warehouse and streaming targets? | ✓Yes. Oracle, MySQL, SQL Server, PostgreSQL, MongoDB, Cassandra, Redis, Elasticsearch, Snowflake, Databricks, Synapse, BigQuery, Redshift, S3/ADLS/GCS data lakes, Spark, Hive and Kafka all use the same pipeline format. |
| How do operators manage it day to day? | ✓CLI, Prometheus metrics and a built-in MCP server, so you can check lag, restart pipelines and re-snapshot tables from Claude, Copilot or Cursor. |
| How is it licensed? | ✓Flat per source database. Not per core, not per row, and not per target. |
| How long to the first replicated row? | ✓Minutes: twincommit check, twincommit snapshot, twincommit run. |
