MySQL Database Development Company

Through InnoDB, MySQL's default storage engine. Transactions are atomic and durable: each commit is written to the redo log before it is acknowledged, and crash recovery replays it after a failure. Isolation defaults to REPEATABLE READ, with READ COMMITTED and SERIALIZABLE available per session, while foreign keys and CHECK constraints keep invalid rows out. Miracuves keeps every table on InnoDB, wraps money and stock changes in short explicit transactions, and keeps innodb_flush_log_at_trx_commit at 1 wherever losing the last second of commits is not acceptable.

If your scope matches a catalogue product, its price is fixed: the ready-made platform - web app, admin panel and mobile apps, on its own stack rather than a MySQL build - starts from $2,199 and ships in 6 working days. Custom MySQL work starts from $3,699, depending on the work, and runs 2-8 weeks; larger scopes are quoted in writing before work starts. Where it lands depends on how many tables, services and applications touch the database, data volume, the replication and failover design, any migration from another database or an old MySQL version, and compliance requirements. A MySQL retainer for continuing work starts from $2,299/month. Your cloud provider bills the database hosting to you directly, separate from our fee. Every quote is written before payment, with no surprise invoices after kickoff.

Three patterns cover most products. A managed standby - Amazon RDS Multi-AZ, Aurora, Cloud SQL or Azure Database for MySQL high availability - is promoted by the provider automatically, under the provider's own SLA. InnoDB Cluster runs Group Replication across three or more servers, with MySQL Router sending traffic to the current primary. Classic source-and-replica replication with ProxySQL in front suits read-heavy products that can accept a scripted failover. Galera-based clusters are an option on MariaDB and Percona XtraDB Cluster rather than Oracle MySQL. We choose from your recovery targets and rehearse the failover before launch.

Asynchronous replication with GTIDs is the default: replicas apply the primary's binary log, serve reads and can be promoted. Semi-synchronous replication makes the primary wait until at least one replica has received each transaction, trading a little write latency for less data at risk in a failover. Group Replication, the basis of InnoDB Cluster, has the members agree on each transaction before it commits. For analytics we add change data capture - Debezium reading the binary log into Kafka - so reports never run on the primary, and we alert on replica lag.

Partitioning splits one large table into pieces inside a single server - usually by date range - so old data can be dropped in an instant and queries that filter on the partition key read fewer pieces. It adds no capacity: every partition shares one server's CPU, memory and disk, and partitioned InnoDB tables cannot have foreign keys. Sharding spreads rows across several MySQL servers by a key such as tenant or customer. That does add capacity, but cross-shard joins and transactions become the application's job, or a layer such as Vitess. We exhaust indexing, read replicas and partitioning first, and shard only when one primary can no longer take the writes.

Backups are automated and proven by restoring them. On a managed service we set the retention period and point-in-time recovery, which replays binary logs to a chosen moment inside that window, and copy snapshots to a second region where the business needs it. On self-managed MySQL we use Percona XtraBackup or MySQL Shell dump utilities plus archived binary logs. A backup that has never been restored does not count: we restore to a scratch instance on a schedule, check row counts and checksums, and record the recovery time in the runbook you receive at handoff.

We start from evidence. The slow query log and Performance Schema digests rank statements by total time, and EXPLAIN ANALYZE shows how each one reads rows. Typical fixes are composite indexes ordered to match the WHERE and ORDER BY, rewriting ORM code that runs one query per row, keyset pagination instead of large OFFSETs, shorter transactions, and an InnoDB buffer pool sized to the working set. Connection pooling in the application or ProxySQL stops connection storms, and Redis absorbs repeated hot reads. Every change is measured before and after on production-sized data.

Each application and service connects with its own MySQL user holding only the privileges it needs, and no application connects as root. Roles group privileges for people, connections require TLS, data at rest is encrypted with the cloud provider's storage encryption or InnoDB tablespace encryption, and passwords live in a secrets manager rather than the repository. Changes are recorded through the managed service's audit logging or an audit table the application writes. We build to the controls SOC 2, PCI DSS, HIPAA or GDPR require; audits and attestations belong to your organization.

We start with an assessment of the source: every table, data type, stored procedure and query pattern, and what has no direct MySQL equivalent - PostgreSQL arrays and custom types, SQL Server T-SQL procedures, or MongoDB documents that have to become tables. Schema conversion is written as migrations, data moves with AWS DMS or a scripted bulk load plus change capture to keep it in sync, and validation compares row counts and checksums table by table. The application runs against MySQL in staging before a planned cutover that keeps a way back.

Miracuves is based in Mumbai and delivers remotely; we have no US office. Overlap hours with your time zone are agreed at kickoff, and first responses come within 2 hours, Mon-Sat 10:00-19:00 IST. You contract with Miracuves as a company - a MySQL engineer, a backend engineer and QA on a written scope - rather than hiring individual developers, and the database runs in your own cloud account, in whichever region you choose, including US regions.

Scope is agreed in writing before any payment, and the first commit follows within 24 hours of sign-off. Custom MySQL work runs 2-8 weeks; larger scopes are quoted in writing before work starts. A catalogue product that already fits goes live in 6 working days on its own stack. Everything we write - schema, migrations, stored routines, scripts, infrastructure code and runbooks - is 100% yours, and the database runs in your cloud account, under your billing, from day one.

MySQL Community Edition is free under the GPL and runs the backend of a great many commercial web and mobile products. Licensing questions come up mainly when you distribute MySQL inside software you sell to others, which may need a commercial license from Oracle. Oracle's paid Enterprise Edition adds tools such as enterprise backup, audit and firewall, and managed cloud services include the database license in their price. We confirm which applies to your product before recommending a setup.
