Migrate to
Supabase

Supabase is PostgreSQL with instant REST/GraphQL APIs and auth built on top, so migrating NoSQL data here means every document becomes a queryable row your existing Supabase client can use immediately. NoSQLSync connects with your Supabase connection string and applies the standard PostgreSQL type mapping.

Supabase is PostgreSQL. Connect it as a PostgreSQL target using the connection string from your project's database settings — every PostgreSQL type mapping below applies unchanged.

How NoSQL types map to Supabase

Source typeSupabase typeNote
ObjectId / String IDVARCHAR(24)Stored as the 24-character hex string; _id becomes the primary key
StringTEXT / VARCHAR(n)Configurable max length or unlimited TEXT
Number / IntegerINTEGER / BIGINTNumeric types mapped to appropriate integer types
Double / DecimalDOUBLE PRECISION / NUMERICFloating point or arbitrary-precision
Date / TimestampTIMESTAMP WITH TIME ZONEFull timezone-aware timestamps
BooleanBOOLEANStandard true/false
Array / ListJSONB / ARRAYNested arrays as JSONB or typed PostgreSQL arrays
Object / Map / Nested docJSONBFlexible schema fields with indexing support
Binary / BytesBYTEABinary data support
Null / MissingNULL (nullable column)Schema-less nulls become SQL-compliant NULL

Migrating to Supabase — FAQ

How long does a migration take?

A typical 100 GB dataset migrates in under 2 hours with bulk mode. With CDC enabled, ongoing writes sync in real time. Total time depends on data volume and network throughput.

Is my data secure during migration?

Yes. All data is encrypted in transit (TLS 1.3) and at rest (AES-256). Database credentials use short-lived tokens. Migration workers run in an isolated environment and never store data after the job completes.

Can I roll back if something goes wrong?

Yes. NoSQLSync only reads from your source — it is never modified, and CDC keeps running until you stop it. If you hit a problem after cutover, point your application's connection string back at the source.
