Simple example of Datahike with S3 backend

Usage

First, build the Lambda uberjar

bb run build

Then deploy infra. This will deploy two Lambda instances, one for writing and one for reading, along with a S3 bucket for data and S3 bucket for storing the Lambda uberjars.

The writer Lambda is configured to use reserved concurrency of 1, so that we would have a single writer only.

Both Lambdas are configured to be accessible via Lambda Function URL without authentication, so you can call them via HTTP.

bb run deploy

Then, migrate schema:

$ curl -X POST $(cat terraform/writer-url.txt) -H "content-type: application/json" -H "X-API-KEY: $(cat terraform/api-key.txt)" -d '{"command": "migrate"}'
"ok"

After this, you can do writes and reads by invoking the Lambdas.

$ curl -X POST $(cat terraform/writer-url.txt) -H "content-type: application/json" -H "X-API-KEY: $(cat terraform/api-key.txt)" -d '{"data": [{"name": "Alice", "age": 32}]}'
"ok"
0% curl $(cat terraform/reader-url.txt)
[[4,"Alice",32]]
