Does your current solution
suffer from these limitations?

Current comparable commercial products
have some or all of the following limitations:
Lack of support and inherent technology limitations for RDS instances
Lack or limited support for DDL operations
High system lag during logical standby data recovery or Disaster Recovery System planning (high availability configuration)
Poor forensic analysis functionality
Challenges inherent in zero downtime upgrade/migration scenarios
High running costs (particularly licensing)
High set up complexity (including support and maintenance during the startup phase)
Complexity and limitation in using replication for real-time database warehousing and real-time reporting systems (due to the inability to extract any reports from the target DB without interfering with normal DB operations)
Lack of cloud-ready capabilities (poor deployment, integration and monitoring functionality), inability to easily integrate with cloud native applications/infrastructures
Lack of data/objects transformation, implementation of complex data processing logic resulting in the inability to integrate with business intelligence systems
Poor implementation of data replication into Data warehouse technologies such as Redshift and Snowflake

Why Repstance?

Repstance is an entirely new, innovative and highly advanced real-time data replication tool based on change data capture (CDC) functionality, which makes database upgrades, migrations and daily operations seamless and nearly instantaneous, while providing continuous or near-continuous operational stability, with zero downtime for rapidly changing databases especially important for mission critical business applications with zero downtime tolerance.

Repstance gives a 360 view into the intricacies of the database replication process with the highest granular health check, with reporting of - replication lags (with cause/consequences analysis), detailed DB replication statistics (including, but not limited to transactions count, objects modification count, DDLs count, average transaction rate calculation, etc.).
