Can I run any script while starting server?

Can I run any script while starting server? or immediately after the started server?

TIA.

Eugeny.

Mmh,
that depends on what your architecture is? What are you trying to do?

Cheers,

I want to start my warmup script while starting server (for example, in my plugin).

[Peter Neubauer]

Mmh,
I don't think there is any explicit lifecycle detection, I think the
easiest way is to expose the endpoint, and call it from outside after
server startup and before you do the regular workload?

If it is for Neo4j server, look into the PluginInitializer SPI that we discussed here:

Perhaps with a plugin lifecycle.

Can you send me small example? TIA.

 in neo4j-server.properties I wrote:

org.neo4j.server.thirdparty_jaxrs_classes=ru.myCompany.neo4j.auto=/auto_warmup/warmup

And my class like as:

package ru.myCompany.neo4j.auto;

import org.neo4j.graphdb.*;

import org.neo4j.tooling.GlobalGraphOperations;

import java.util.Iterator;

import javax.ws.rs.GET;

import javax.ws.rs.Path;

import javax.ws.rs.core.Response;

import javax.ws.rs.core.Response.Status;

import javax.ws.rs.core.MediaType;

import javax.ws.rs.Produces;

@Path( "/auto_warmup" )

public class autoWarmUp {

   private final GraphDatabaseService graphDb;

   public autoWarmUp(final GraphDatabaseService gdb) {

    graphDb = gdb;

   }

   @GET

   @Produces( MediaType.TEXT_PLAIN )

   @Path( "/warmup" )

   public Response warmup()

   {

GlobalGraphOperations gg = GlobalGraphOperations.at(graphDb);

Iterator<Node> iter = gg.getAllNodes().iterator();

Node node;

int relCount = 0;

int nCount = 0;

while ( iter.hasNext() ) {

node = iter.next();

nCount++;

for ( Relationship rel: node.getRelationships() ) {

if ( rel.hasProperty("type") ) {

relCount++;

}

}

}

       return Response.status( Status.OK ).entity(

        ( "WARM UP: " + nCount + " nodes and " + relCount + " relationships." ).getBytes() ).build();

   }

}

Can I run this script automatically on starting server?
