### Using @cacheBy

Since v2.0.0 @cacheBy decorator introduced and helps simplify caching 
invalidation definition for those service methods which rely on a root sequelize
model output. In combination of passing the fields map to such service methods
it will also provide more efficient caching for the method calls.

Take a look at such example: 

~~~typescript
import { IMQService, expose } from '@imqueue/rpc';
import { PgCache, cacheBy } from '@imqueue/pg-cache';
import {
 FieldsInput,
 FindOptions,
 OrderByInput,
 PaginationInput,
 query,
} from '@imqueue/sequelize';
import { cacheConfig } from '../config';
import { MyDbEntity } from './orm/models';
import { MyDbEntityFilter } from './types';
import withRangeFilters = query.withRangeFilters;
import autoCountQuery = query.autoCountQuery;
import autoQuery = query.autoQuery;
import toWhereOptions = query.toWhereOptions;
import toLimitOptions = query.toLimitOptions;
import toOrderOptions = query.toOrderOptions;

@PgCache(cacheConfig)
class MyCoolService extends IMQService {
 @expose()
 @cacheBy(MyDbEntity, { fieldsArg: 1 })
 public async listEntities(
 filter?: MyDbEntityFilter,
 fields?: FieldsInput,
 pageOptions?: PaginationInput,
 orderBy?: OrderByInput,
 ): Promise<{ total: number, data: MyDbEntity[] }> {
 const where = toWhereOptions<MyDbEntityFilter>(
 withRangeFilters(filter),
 MyDbEntityFilter,
 );
 const countQuery = autoCountQuery(MyDbEntity, fields, where);
 const findQuery = autoQuery<FindOptions>(
 MyDbEntity, fields, where,
 toLimitOptions<MyDbEntity>(pageOptions),
 toOrderOptions(orderBy),
 );
 const [total, data] = await Promise.all([
 MyDbEntity.count(countQuery),
 MyDbEntity.findAll(findQuery),
 ]);

 return { total, data } as { total: number, data: MyDbEntity[] };
 }
}
~~~

By doing so, `@cacheBy` will take care of invalidating only those queries
which has selection of fields matching db changes events, so if the actual
query was not selecting some joined data, but there was a change only on that
joined data - cache won't invalidate, as far as real selection was not 
influenced by a data change. And yes, it will automatically monitor
all related to the root model entities for changes and match them with runtime
selections. This makes caching more efficient and more obvious for
developer.
